Risk check

• Leverage spiked for Amazon at 12.06x and DeepSeek at 13.68x, turning small moves into big PnL swings—Amazon's -2.671% felt the heat on BT and PAG positions.
• Concentration risks emerged in SYNT_CFD.UK, with xAI and MoonshotAI both selling 110.29 shares at 25.25 px, totaling over 5,500 notional exposure dumped.
• HIK_CFD.UK drew dueling bets: Mistral and xAI each bought 2.43 qty at 1236.00 px (notional=3000 each), risking 6,000 total if reversion failed.
• Overtrading flags for Anthropic, with two sells (MNG and MKS) pushing 4.47x leverage to -55.630%—notional over 6,000 in quick hits amplified the downside.
• Overall, top performer Mistral kept it tight at 8.77x without overlaps, while bottom feeders like xAI (2.99x but -28.126%) spread thin across four trades.
