The distance from MA50 is -18.6%).\n    *   Vol: 150%\n    *   *Analysis:* High volatility, big drop.

I have a mix of extreme oversold (Long) and extreme overbought (Short).\nThe strategy is \"Mean Reversion\".\nLet's pick the most extreme moves that aren't obviously broken (e.g., volatility > 1000% like IWG or HUBS is likely bad data or a corporate action/spinoff).\n\n*   **PAGE_CFD.UK:** -36% drop, -40% from MA200. Very strong signal.\n*   **OCDO_CFD.UK:** -27% drop, -25% from MA200. Strong signal.\n*   **CBG_CFD.UK:** -26% drop, -22% from MA50. Strong signal.\n*   **RS1_CFD.UK:** +24% rise, +26% from MA200. Strong signal.\n*   **BOY_CFD.UK:** +24% rise, +28% from MA200. Strong signal.\n\nLet's check sector concentration. Sectors are unknown, so I ignore it.\nLet's check binary events. Without news, I rely on the magnitude. A 36% drop in one day (PAGE) is huge, often binary (profit warning). However, the prompt says \"Avoid highly binary/event-driven moves (if known)\". Since it's not known (news is empty), I treat it as a statistical anomaly to trade. But 36% is extreme. Let's look for slightly less extreme but still significant moves to be safer, or stick to the top 5 extremes if the strategy implies catching falling knives.\n\nLet's look at the volatility.\nPAGE: 193%\nOCDO: 249%\nCBG: 169%\nRS1: 102%\nBOY: 103%\n\nThese are high but manageable compared to IWG (8127%) or HUBS (7372%).\n\nLet's refine the list to the top 5 based on combined distance from MA50/200 and 1-day change.\n\n1.  **PAGE_CFD.UK** (Long): -36.8% 1d, -40.6% MA200.\n2.  **OCDO_CFD.UK** (Long): -27.7% 1d, -25.4% MA200.\n3.  **CBG_CFD.UK** (Long): -26.6% 1d, -22.1% MA50.\n4.  **JUP_CFD.UK** (Short): +22.1% 1d, +57.7% MA200. (The MA200 deviation here is massive compared to RS1/BOY).\n5.  **RS1_CFD.UK** (Short): +23.9% 1d, +26.4% MA200.\n\nWait, let's look at **BOY_CFD.UK** vs **RS1_CFD.UK**.\nBOY: +24.2% 1d, +28.6% MA200.\nRS1: +23.9% 1d, +26.4% MA200.\nVery similar. BOY is slightly more extended on MA200.\n\nLet's look at **HAS_CFD.UK** vs **THG_CFD.UK**.\nTHG: -21.5% 1d, -18.6% MA50. (MA200 is positive, suggesting a recent high peak).\nHAS: -17.2% 1d, -26.5% MA200. (More consistent downtrend/breakdown).\nHAS seems like a cleaner mean reversion play (trend following the drop) vs THG (crashing from highs).\n\nSo the list:\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. BOY_CFD.UK (or RS1)\n\nLet's swap BOY for RS1? RS1 has slightly lower vol (102 vs 103). Negligible.\nLet's look at **PNN_CFD.UK** (Pennon): +16.6% 1d, +23.7% MA200. Less extreme than JUP/RS1/BOY.\n\nI will stick to the most extreme 5.\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short) - The MA200 deviation of +57% is huge.\n5. RS1_CFD.UK (Short) - +23.9% 1d.\n\nLet's check if I should include **HAS_CFD.UK** instead of one of the shorts?\nStrategy is \"Mean Reversion\". It can be Long or Short.\nI have 3 Longs and 2 Shorts. That's a balanced portfolio.\n\nLet's verify the \"Avoid highly binary/event-driven moves\" constraint again.\nPAGE dropped 36%. That is almost certainly a profit warning or major news. However, the instructions say \"if known\". News is empty. I must select based on technicals. The technicals scream \"oversold\".\n\nLet's check **CRST_CFD.UK**. -12.8% 1d, -28% MA200. Volatility is 236%. That's getting high.\n**ESNT_CFD.UK**: -10.6% 1d. Not as extreme.\n\nI will proceed with PAGE, OCDO, CBG, JUP, RS1.\n\n**Scoring (0-100):**\nI need to assign a `mean_reversion_score`.\nLogic: High deviation + High 1-day move = High score.\nPAGE: 36% drop + 40% MA200 dev. Score: 95.\nOCDO: 27% drop + 25% MA200 dev. Score: 90.\nCBG: 26% drop + 22% MA50 dev. Score: 88.\nJUP: 22% rise + 57% MA200 dev. Score: 92 (The MA200 dev is the key here).\nRS1: 24% rise + 26% MA200 dev. Score: 85.\n\n**Selection Reasons:**\nMust be \"short, concrete, indicator-based\".\ne.g., \"Extreme -36% 1d drop, -40% below MA200\".\n\n**Rejected Common Reasons:**\n\"Insufficient deviation from mean\", \"Low volatility\", \"Data quality issues (null MA)\", \"Region mismatch (US symbols)\".\n\nWait, I should check if I should reject US symbols.\nRegion: \"EU\".\nUniverse contains: HUBS_CFD.US, SMG_CFD.US, COTY_CFD.US, CABO_CFD.US.\nUsually, in these tasks, if the region is specified as EU, I should filter out US symbols unless the strategy explicitly allows global. The strategy rules say `universe_symbols_eu: []` and `universe_symbols_us: []`, implying the provided list is the *result* of a scan or the input universe. The input universe contains mixed. However, the task is `stage1_universe_scan` for `region: \"EU\"`. It is safer to stick to EU symbols (ending in .UK or .EU) to respect the region constraint.\nMy selected list (PAGE, OCDO, CBG, JUP, RS1) are all .UK. So this is consistent.\n\nLet's double check the list.\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. RS1_CFD.UK\n\nAre there any others?\n**BOY_CFD.UK**: +24.16% 1d. RS1 is +23.91%. BOY is slightly higher.\n**RSW_CFD.UK**: +18.15% 1d.\n**PNN_CFD.UK**: +16.5% 1d.\n\nBetween RS1 and BOY:\nRS1: Dist MA200 26.4%, Dist MA50 23.7%.\nBOY: Dist MA200 28.6%, Dist MA50 18.6%.\nBOY is more extended from MA200. RS1 is more extended from MA50.\nBOY's 1d change is slightly higher.\nI'll pick BOY over RS1 because the MA200 deviation is larger (28.6 vs 26.4), suggesting a stronger reversion potential on a longer timeframe, though the horizon is short term.\nActually, RS1's MA50 deviation is higher (23.7 vs 18.6). Short term mean reversion (2-10 days) relies more on MA50.\nLet's stick with RS1 or swap to BOY. It's a toss-up. I'll stick with RS1 for now as it appeared first in the list and the stats are very similar. Or I can use BOY. Let's look at the 1d change again. BOY 24.16 vs RS1 23.91. BOY is stronger.\nLet's look at **HAS_CFD.UK** again. -17% 1d.\n**CRST_CFD.UK**: -12.8% 1d.\n**THG_CFD.UK**: -21.5% 1d.\nTHG is -21.5%. CBG is -26.6%. OCDO is -27.7%. PAGE is -36.8%.\nTHG is a contender. Why did I exclude it?\nDist MA200: +2.7%. Dist MA50: -18.6%.\nCBG Dist MA200: -13.3%. Dist MA50: -22.1%.\nOCDO Dist MA200: -25.4%. Dist MA50: -16.5%.\nPAGE Dist MA200: -40.6%. Dist MA50: -31.7%.\nTHG is crashing from a higher level (MA200 positive). The others are in downtrends (MA200 negative). Mean reversion often works better when the price snaps back to a declining MA200 (short covering) or bounces off support. THG might be a \"falling knife\" with no support yet (MA200 is way above).\nI will stick to PAGE, OCDO, CBG as the longs.\n\nFor shorts:\nJUP (+22%, +57% MA200).\nBOY (+24%, +28% MA200).\nRS1 (+24%, +26% MA200).\nRSW (+18%, +36% MA200).\nPNN (+16%, +23% MA200).\n\nJUP is the clear #1 short due to the massive MA200 deviation.\nBetween BOY and RS1:\nBOY: 1d +24.2%, MA50 +18.6%.\nRS1: 1d +23.9%, MA50 +23.7%.\nRS1 is more extended from the MA50 (short term mean). BOY is more extended from MA200 (long term mean).\nGiven the 2-10 day horizon, MA50 is more relevant.\nI will select RS1 over BOY.\n\nFinal 5:\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short)\n5. RS1_CFD.UK (Short)\n\nLet's refine the scores.\nPAGE: 95\nOCDO: 90\nCBG: 88\nJUP: 92\nRS1: 85\n\nWait, I should check if I can find a 5th candidate that is better than RS1.\nWhat about **HBR_CFD.UK**? -2.3% 1d. No.\n**CNA_CFD.UK**? +8.4% 1d. No.\n**MAB_CFD.UK**? +14.3% 1d. No.\n**DLN_CFD.UK**? +10.4% 1d. No.\n\nRS1 seems the best of the remaining.\n\nLet's check **IPO_CFD",

Let's look for slightly less extreme but still significant moves to be safer, or stick to the top 5 extremes if the strategy implies catching falling knives.\n\nLet's look at the volatility.\nPAGE: 193%\nOCDO: 249%\nCBG: 169%\nRS1: 102%\nBOY: 103%\n\nThese are high but manageable compared to IWG (8127%) or HUBS (7372%).\n\nLet's refine the list to the top 5 based on combined distance from MA50/200 and 1-day change.\n\n1.  **PAGE_CFD.UK** (Long): -36.8% 1d, -40.6% MA200.\n2.  **OCDO_CFD.UK** (Long): -27.7% 1d, -25.4% MA200.\n3.  **CBG_CFD.UK** (Long): -26.6% 1d, -22.1% MA50.\n4.  **JUP_CFD.UK** (Short): +22.1% 1d, +57.7% MA200. (The MA200 deviation here is massive compared to RS1/BOY).\n5.  **RS1_CFD.UK** (Short): +23.9% 1d, +26.4% MA200.\n\nWait, let's look at **BOY_CFD.UK** vs **RS1_CFD.UK**.\nBOY: +24.2% 1d, +28.6% MA200.\nRS1: +23.9% 1d, +26.4% MA200.\nVery similar. BOY is slightly more extended on MA200.\n\nLet's look at **HAS_CFD.UK** vs **THG_CFD.UK**.\nTHG: -21.5% 1d, -18.6% MA50. (MA200 is positive, suggesting a recent high peak).\nHAS: -17.2% 1d, -26.5% MA200. (More consistent downtrend/breakdown).\nHAS seems like a cleaner mean reversion play (trend following the drop) vs THG (crashing from highs).\n\nSo the list:\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. BOY_CFD.UK (or RS1)\n\nLet's swap BOY for RS1? RS1 has slightly lower vol (102 vs 103). Negligible.\nLet's look at **PNN_CFD.UK** (Pennon): +16.6% 1d, +23.7% MA200. Less extreme than JUP/RS1/BOY.\n\nI will stick to the most extreme 5.\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short) - The MA200 deviation of +57% is huge.\n5. RS1_CFD.UK (Short) - +23.9% 1d.\n\nLet's check if I should include **HAS_CFD.UK** instead of one of the shorts?\nStrategy is \"Mean Reversion\". It can be Long or Short.\nI have 3 Longs and 2 Shorts. That's a balanced portfolio.\n\nLet's verify the \"Avoid highly binary/event-driven moves\" constraint again.\nPAGE dropped 36%. That is almost certainly a profit warning or major news. However, the instructions say \"if known\". News is empty. I must select based on technicals. The technicals scream \"oversold\".\n\nLet's check **CRST_CFD.UK**. -12.8% 1d, -28% MA200. Volatility is 236%. That's getting high.\n**ESNT_CFD.UK**: -10.6% 1d. Not as extreme.\n\nI will proceed with PAGE, OCDO, CBG, JUP, RS1.\n\n**Scoring (0-100):**\nI need to assign a `mean_reversion_score`.\nLogic: High deviation + High 1-day move = High score.\nPAGE: 36% drop + 40% MA200 dev. Score: 95.\nOCDO: 27% drop + 25% MA200 dev. Score: 90.\nCBG: 26% drop + 22% MA50 dev. Score: 88.\nJUP: 22% rise + 57% MA200 dev. Score: 92 (The MA200 dev is the key here).\nRS1: 24% rise + 26% MA200 dev. Score: 85.\n\n**Selection Reasons:**\nMust be \"short, concrete, indicator-based\".\ne.g., \"Extreme -36% 1d drop, -40% below MA200\".\n\n**Rejected Common Reasons:**\n\"Insufficient deviation from mean\", \"Low volatility\", \"Data quality issues (null MA)\", \"Region mismatch (US symbols)\".\n\nWait, I should check if I should reject US symbols.\nRegion: \"EU\".\nUniverse contains: HUBS_CFD.US, SMG_CFD.US, COTY_CFD.US, CABO_CFD.US.\nUsually, in these tasks, if the region is specified as EU, I should filter out US symbols unless the strategy explicitly allows global. The strategy rules say `universe_symbols_eu: []` and `universe_symbols_us: []`, implying the provided list is the *result* of a scan or the input universe. The input universe contains mixed. However, the task is `stage1_universe_scan` for `region: \"EU\"`. It is safer to stick to EU symbols (ending in .UK or .EU) to respect the region constraint.\nMy selected list (PAGE, OCDO, CBG, JUP, RS1) are all .UK. So this is consistent.\n\nLet's double check the list.\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. RS1_CFD.UK\n\nAre there any others?\n**BOY_CFD.UK**: +24.16% 1d. RS1 is +23.91%. BOY is slightly higher.\n**RSW_CFD.UK**: +18.15% 1d.\n**PNN_CFD.UK**: +16.5% 1d.\n\nBetween RS1 and BOY:\nRS1: Dist MA200 26.4%, Dist MA50 23.7%.\nBOY: Dist MA200 28.6%, Dist MA50 18.6%.\nBOY is more extended from MA200. RS1 is more extended from MA50.\nBOY's 1d change is slightly higher.\nI'll pick BOY over RS1 because the MA200 deviation is larger (28.6 vs 26.4), suggesting a stronger reversion potential on a longer timeframe, though the horizon is short term.\nActually, RS1's MA50 deviation is higher (23.7 vs 18.6). Short term mean reversion (2-10 days) relies more on MA50.\nLet's stick with RS1 or swap to BOY. It's a toss-up. I'll stick with RS1 for now as it appeared first in the list and the stats are very similar. Or I can use BOY. Let's look at the 1d change again. BOY 24.16 vs RS1 23.91. BOY is stronger.\nLet's look at **HAS_CFD.UK** again. -17% 1d.\n**CRST_CFD.UK**: -12.8% 1d.\n**THG_CFD.UK**: -21.5% 1d.\nTHG is -21.5%. CBG is -26.6%. OCDO is -27.7%. PAGE is -36.8%.\nTHG is a contender. Why did I exclude it?\nDist MA200: +2.7%. Dist MA50: -18.6%.\nCBG Dist MA200: -13.3%. Dist MA50: -22.1%.\nOCDO Dist MA200: -25.4%. Dist MA50: -16.5%.\nPAGE Dist MA200: -40.6%. Dist MA50: -31.7%.\nTHG is crashing from a higher level (MA200 positive). The others are in downtrends (MA200 negative). Mean reversion often works better when the price snaps back to a declining MA200 (short covering) or bounces off support. THG might be a \"falling knife\" with no support yet (MA200 is way above).\nI will stick to PAGE, OCDO, CBG as the longs.\n\nFor shorts:\nJUP (+22%, +57% MA200).\nBOY (+24%, +28% MA200).\nRS1 (+24%, +26% MA200).\nRSW (+18%, +36% MA200).\nPNN (+16%, +23% MA200).\n\nJUP is the clear #1 short due to the massive MA200 deviation.\nBetween BOY and RS1:\nBOY: 1d +24.2%, MA50 +18.6%.\nRS1: 1d +23.9%, MA50 +23.7%.\nRS1 is more extended from the MA50 (short term mean). BOY is more extended from MA200 (long term mean).\nGiven the 2-10 day horizon, MA50 is more relevant.\nI will select RS1 over BOY.\n\nFinal 5:\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short)\n5. RS1_CFD.UK (Short)\n\nLet's refine the scores.\nPAGE: 95\nOCDO: 90\nCBG: 88\nJUP: 92\nRS1: 85\n\nWait, I should check if I can find a 5th candidate that is better than RS1.\nWhat about **HBR_CFD.UK**? -2.3% 1d. No.\n**CNA_CFD.UK**? +8.4% 1d. No.\n**MAB_CFD.UK**? +14.3% 1d. No.\n**DLN_CFD.UK**? +10.4% 1d. No.\n\nRS1 seems the best of the remaining.\n\nLet's check **IPO_CFD",

Very strong signal.\n*   **OCDO_CFD.UK:** -27% drop, -25% from MA200. Strong signal.\n*   **CBG_CFD.UK:** -26% drop, -22% from MA50. Strong signal.\n*   **RS1_CFD.UK:** +24% rise, +26% from MA200. Strong signal.\n*   **BOY_CFD.UK:** +24% rise, +28% from MA200. Strong signal.\n\nLet's check sector concentration. Sectors are unknown, so I ignore it.\nLet's check binary events. Without news, I rely on the magnitude. A 36% drop in one day (PAGE) is huge, often binary (profit warning). However, the prompt says \"Avoid highly binary/event-driven moves (if known)\". Since it's not known (news is empty), I treat it as a statistical anomaly to trade. But 36% is extreme. Let's look for slightly less extreme but still significant moves to be safer, or stick to the top 5 extremes if the strategy implies catching falling knives.\n\nLet's look at the volatility.\nPAGE: 193%\nOCDO: 249%\nCBG: 169%\nRS1: 102%\nBOY: 103%\n\nThese are high but manageable compared to IWG (8127%) or HUBS (7372%).\n\nLet's refine the list to the top 5 based on combined distance from MA50/200 and 1-day change.\n\n1.  **PAGE_CFD.UK** (Long): -36.8% 1d, -40.6% MA200.\n2.  **OCDO_CFD.UK** (Long): -27.7% 1d, -25.4% MA200.\n3.  **CBG_CFD.UK** (Long): -26.6% 1d, -22.1% MA50.\n4.  **JUP_CFD.UK** (Short): +22.1% 1d, +57.7% MA200. (The MA200 deviation here is massive compared to RS1/BOY).\n5.  **RS1_CFD.UK** (Short): +23.9% 1d, +26.4% MA200.\n\nWait, let's look at **BOY_CFD.UK** vs **RS1_CFD.UK**.\nBOY: +24.2% 1d, +28.6% MA200.\nRS1: +23.9% 1d, +26.4% MA200.\nVery similar. BOY is slightly more extended on MA200.\n\nLet's look at **HAS_CFD.UK** vs **THG_CFD.UK**.\nTHG: -21.5% 1d, -18.6% MA50. (MA200 is positive, suggesting a recent high peak).\nHAS: -17.2% 1d, -26.5% MA200. (More consistent downtrend/breakdown).\nHAS seems like a cleaner mean reversion play (trend following the drop) vs THG (crashing from highs).\n\nSo the list:\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. BOY_CFD.UK (or RS1)\n\nLet's swap BOY for RS1? RS1 has slightly lower vol (102 vs 103). Negligible.\nLet's look at **PNN_CFD.UK** (Pennon): +16.6% 1d, +23.7% MA200. Less extreme than JUP/RS1/BOY.\n\nI will stick to the most extreme 5.\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short) - The MA200 deviation of +57% is huge.\n5. RS1_CFD.UK (Short) - +23.9% 1d.\n\nLet's check if I should include **HAS_CFD.UK** instead of one of the shorts?\nStrategy is \"Mean Reversion\". It can be Long or Short.\nI have 3 Longs and 2 Shorts. That's a balanced portfolio.\n\nLet's verify the \"Avoid highly binary/event-driven moves\" constraint again.\nPAGE dropped 36%. That is almost certainly a profit warning or major news. However, the instructions say \"if known\". News is empty. I must select based on technicals. The technicals scream \"oversold\".\n\nLet's check **CRST_CFD.UK**. -12.8% 1d, -28% MA200. Volatility is 236%. That's getting high.\n**ESNT_CFD.UK**: -10.6% 1d. Not as extreme.\n\nI will proceed with PAGE, OCDO, CBG, JUP, RS1.\n\n**Scoring (0-100):**\nI need to assign a `mean_reversion_score`.\nLogic: High deviation + High 1-day move = High score.\nPAGE: 36% drop + 40% MA200 dev. Score: 95.\nOCDO: 27% drop + 25% MA200 dev. Score: 90.\nCBG: 26% drop + 22% MA50 dev. Score: 88.\nJUP: 22% rise + 57% MA200 dev. Score: 92 (The MA200 dev is the key here).\nRS1: 24% rise + 26% MA200 dev. Score: 85.\n\n**Selection Reasons:**\nMust be \"short, concrete, indicator-based\".\ne.g., \"Extreme -36% 1d drop, -40% below MA200\".\n\n**Rejected Common Reasons:**\n\"Insufficient deviation from mean\", \"Low volatility\", \"Data quality issues (null MA)\", \"Region mismatch (US symbols)\".\n\nWait, I should check if I should reject US symbols.\nRegion: \"EU\".\nUniverse contains: HUBS_CFD.US, SMG_CFD.US, COTY_CFD.US, CABO_CFD.US.\nUsually, in these tasks, if the region is specified as EU, I should filter out US symbols unless the strategy explicitly allows global. The strategy rules say `universe_symbols_eu: []` and `universe_symbols_us: []`, implying the provided list is the *result* of a scan or the input universe. The input universe contains mixed. However, the task is `stage1_universe_scan` for `region: \"EU\"`. It is safer to stick to EU symbols (ending in .UK or .EU) to respect the region constraint.\nMy selected list (PAGE, OCDO, CBG, JUP, RS1) are all .UK. So this is consistent.\n\nLet's double check the list.\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. RS1_CFD.UK\n\nAre there any others?\n**BOY_CFD.UK**: +24.16% 1d. RS1 is +23.91%. BOY is slightly higher.\n**RSW_CFD.UK**: +18.15% 1d.\n**PNN_CFD.UK**: +16.5% 1d.\n\nBetween RS1 and BOY:\nRS1: Dist MA200 26.4%, Dist MA50 23.7%.\nBOY: Dist MA200 28.6%, Dist MA50 18.6%.\nBOY is more extended from MA200. RS1 is more extended from MA50.\nBOY's 1d change is slightly higher.\nI'll pick BOY over RS1 because the MA200 deviation is larger (28.6 vs 26.4), suggesting a stronger reversion potential on a longer timeframe, though the horizon is short term.\nActually, RS1's MA50 deviation is higher (23.7 vs 18.6). Short term mean reversion (2-10 days) relies more on MA50.\nLet's stick with RS1 or swap to BOY. It's a toss-up. I'll stick with RS1 for now as it appeared first in the list and the stats are very similar. Or I can use BOY. Let's look at the 1d change again. BOY 24.16 vs RS1 23.91. BOY is stronger.\nLet's look at **HAS_CFD.UK** again. -17% 1d.\n**CRST_CFD.UK**: -12.8% 1d.\n**THG_CFD.UK**: -21.5% 1d.\nTHG is -21.5%. CBG is -26.6%. OCDO is -27.7%. PAGE is -36.8%.\nTHG is a contender. Why did I exclude it?\nDist MA200: +2.7%. Dist MA50: -18.6%.\nCBG Dist MA200: -13.3%. Dist MA50: -22.1%.\nOCDO Dist MA200: -25.4%. Dist MA50: -16.5%.\nPAGE Dist MA200: -40.6%. Dist MA50: -31.7%.\nTHG is crashing from a higher level (MA200 positive). The others are in downtrends (MA200 negative). Mean reversion often works better when the price snaps back to a declining MA200 (short covering) or bounces off support. THG might be a \"falling knife\" with no support yet (MA200 is way above).\nI will stick to PAGE, OCDO, CBG as the longs.\n\nFor shorts:\nJUP (+22%, +57% MA200).\nBOY (+24%, +28% MA200).\nRS1 (+24%, +26% MA200).\nRSW (+18%, +36% MA200).\nPNN (+16%, +23% MA200).\n\nJUP is the clear #1 short due to the massive MA200 deviation.\nBetween BOY and RS1:\nBOY: 1d +24.2%, MA50 +18.6%.\nRS1: 1d +23.9%, MA50 +23.7%.\nRS1 is more extended from the MA50 (short term mean). BOY is more extended from MA200 (long term mean).\nGiven the 2-10 day horizon, MA50 is more relevant.\nI will select RS1 over BOY.\n\nFinal 5:\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short)\n5. RS1_CFD.UK (Short)\n\nLet's refine the scores.\nPAGE: 95\nOCDO: 90\nCBG: 88\nJUP: 92\nRS1: 85\n\nWait, I should check if I can find a 5th candidate that is better than RS1.\nWhat about **HBR_CFD.UK**? -2.3% 1d. No.\n**CNA_CFD.UK**? +8.4% 1d. No.\n**MAB_CFD.UK**? +14.3% 1d. No.\n**DLN_CFD.UK**? +10.4% 1d. No.\n\nRS1 seems the best of the remaining.\n\nLet's check **IPO_CFD",

However, the instructions say \"if known\". News is empty. I must select based on technicals. The technicals scream \"oversold\".\n\nLet's check **CRST_CFD.UK**. -12.8% 1d, -28% MA200. Volatility is 236%. That's getting high.\n**ESNT_CFD.UK**: -10.6% 1d. Not as extreme.\n\nI will proceed with PAGE, OCDO, CBG, JUP, RS1.\n\n**Scoring (0-100):**\nI need to assign a `mean_reversion_score`.\nLogic: High deviation + High 1-day move = High score.\nPAGE: 36% drop + 40% MA200 dev. Score: 95.\nOCDO: 27% drop + 25% MA200 dev. Score: 90.\nCBG: 26% drop + 22% MA50 dev. Score: 88.\nJUP: 22% rise + 57% MA200 dev. Score: 92 (The MA200 dev is the key here).\nRS1: 24% rise + 26% MA200 dev. Score: 85.\n\n**Selection Reasons:**\nMust be \"short, concrete, indicator-based\".\ne.g., \"Extreme -36% 1d drop, -40% below MA200\".\n\n**Rejected Common Reasons:**\n\"Insufficient deviation from mean\", \"Low volatility\", \"Data quality issues (null MA)\", \"Region mismatch (US symbols)\".\n\nWait, I should check if I should reject US symbols.\nRegion: \"EU\".\nUniverse contains: HUBS_CFD.US, SMG_CFD.US, COTY_CFD.US, CABO_CFD.US.\nUsually, in these tasks, if the region is specified as EU, I should filter out US symbols unless the strategy explicitly allows global. The strategy rules say `universe_symbols_eu: []` and `universe_symbols_us: []`, implying the provided list is the *result* of a scan or the input universe. The input universe contains mixed. However, the task is `stage1_universe_scan` for `region: \"EU\"`. It is safer to stick to EU symbols (ending in .UK or .EU) to respect the region constraint.\nMy selected list (PAGE, OCDO, CBG, JUP, RS1) are all .UK. So this is consistent.\n\nLet's double check the list.\n1. PAGE_CFD.UK\n2. OCDO_CFD.UK\n3. CBG_CFD.UK\n4. JUP_CFD.UK\n5. RS1_CFD.UK\n\nAre there any others?\n**BOY_CFD.UK**: +24.16% 1d. RS1 is +23.91%. BOY is slightly higher.\n**RSW_CFD.UK**: +18.15% 1d.\n**PNN_CFD.UK**: +16.5% 1d.\n\nBetween RS1 and BOY:\nRS1: Dist MA200 26.4%, Dist MA50 23.7%.\nBOY: Dist MA200 28.6%, Dist MA50 18.6%.\nBOY is more extended from MA200. RS1 is more extended from MA50.\nBOY's 1d change is slightly higher.\nI'll pick BOY over RS1 because the MA200 deviation is larger (28.6 vs 26.4), suggesting a stronger reversion potential on a longer timeframe, though the horizon is short term.\nActually, RS1's MA50 deviation is higher (23.7 vs 18.6). Short term mean reversion (2-10 days) relies more on MA50.\nLet's stick with RS1 or swap to BOY. It's a toss-up. I'll stick with RS1 for now as it appeared first in the list and the stats are very similar. Or I can use BOY. Let's look at the 1d change again. BOY 24.16 vs RS1 23.91. BOY is stronger.\nLet's look at **HAS_CFD.UK** again. -17% 1d.\n**CRST_CFD.UK**: -12.8% 1d.\n**THG_CFD.UK**: -21.5% 1d.\nTHG is -21.5%. CBG is -26.6%. OCDO is -27.7%. PAGE is -36.8%.\nTHG is a contender. Why did I exclude it?\nDist MA200: +2.7%. Dist MA50: -18.6%.\nCBG Dist MA200: -13.3%. Dist MA50: -22.1%.\nOCDO Dist MA200: -25.4%. Dist MA50: -16.5%.\nPAGE Dist MA200: -40.6%. Dist MA50: -31.7%.\nTHG is crashing from a higher level (MA200 positive). The others are in downtrends (MA200 negative). Mean reversion often works better when the price snaps back to a declining MA200 (short covering) or bounces off support. THG might be a \"falling knife\" with no support yet (MA200 is way above).\nI will stick to PAGE, OCDO, CBG as the longs.\n\nFor shorts:\nJUP (+22%, +57% MA200).\nBOY (+24%, +28% MA200).\nRS1 (+24%, +26% MA200).\nRSW (+18%, +36% MA200).\nPNN (+16%, +23% MA200).\n\nJUP is the clear #1 short due to the massive MA200 deviation.\nBetween BOY and RS1:\nBOY: 1d +24.2%, MA50 +18.6%.\nRS1: 1d +23.9%, MA50 +23.7%.\nRS1 is more extended from the MA50 (short term mean). BOY is more extended from MA200 (long term mean).\nGiven the 2-10 day horizon, MA50 is more relevant.\nI will select RS1 over BOY.\n\nFinal 5:\n1. PAGE_CFD.UK (Long)\n2. OCDO_CFD.UK (Long)\n3. CBG_CFD.UK (Long)\n4. JUP_CFD.UK (Short)\n5. RS1_CFD.UK (Short)\n\nLet's refine the scores.\nPAGE: 95\nOCDO: 90\nCBG: 88\nJUP: 92\nRS1: 85\n\nWait, I should check if I can find a 5th candidate that is better than RS1.\nWhat about **HBR_CFD.UK**? -2.3% 1d. No.\n**CNA_CFD.UK**? +8.4% 1d. No.\n**MAB_CFD.UK**? +14.3% 1d. No.\n**DLN_CFD.UK**? +10.4% 1d. No.\n\nRS1 seems the best of the remaining.\n\nLet's check **IPO_CFD",
