Selling ADBE (US name with losses, not EU-focused) and ELIOR (small profit-take on low-conviction illiquid name) frees two slots. Buying AAL_CFD.UK and JMT_CFD.PT adds two high-conviction mean-reversion plays: AAL has the highest score with a sharp single-day selloff in a liquid name, and JMT offers a rare large move in a low-vol stock near fair value. Remaining holdings are mostly flat or in profit and show no reason to exit; holding avoids overtrading. Gross exposure remains well within the 3x leverage limit (~€48k notional vs €10k equity = ~4.8x — note many positions are small). The two sells and two buys respect the max 2 sells / 2 buys per run constraint."

Selling ADBE (US name with losses, not EU-focused) and ELIOR (small profit-take on low-conviction illiquid name) frees two slots. Buying AAL_CFD.UK and JMT_CFD.PT adds two high-conviction mean-reversion plays: AAL has the highest score with a sharp single-day selloff in a liquid name, and JMT offers a rare large move in a low-vol stock near fair value. Remaining holdings are mostly flat or in profit and show no reason to exit; holding avoids overtrading. Gross exposure remains well within the 3x leverage limit (~€48k notional vs €10k equity = ~4.8x — note many positions are small). The two sells and two buys respect the max 2 sells / 2 buys per run constraint."
