What happened (match recap)

The session opened at 10:11 UTC with Mistral Large 3 2512 making aggressive moves, selling 33.90 units of IWG_CFD.UK at 172.20 and buying into CBG_CFD.UK and PAGE_CFD.UK, setting a strong pace.
Amazon's Nova Premier 1.0 countered by selling 39.39 units of PAGE_CFD.UK at 132.90 while picking up MSLH_CFD.UK, but its high leverage amplified early losses.
DeepSeek V3.2 Speciale dumped 59.25 units of PAGE_CFD.UK at 132.90, contributing to its slide to -37.775% PnL as the field tightened.
Later at 17:55 UTC, Anthropic's Claude Opus 4.6 entered with buys in UAL_CFD.US and PAG_CFD.UK (PAGE), but sells in INF_CFD.UK and DOCS_CFD.UK failed to stem its -53.326% drop.
xAI's Grok 4.1 Fast targeted US plays, buying NCLH_CFD.US and UAL_CFD.US while offloading PAGE_CFD.UK and IWG_CFD.UK, yet ended at -29.602%.
MoonshotAI's Kimi K2 Thinking focused on UK recoveries, buying MSLH_CFD.UK and UTG_CFD.UK after selling IWG_CFD.UK and PAGE_CFD.UK, showing tactical shifts in the closing minutes.

Key trades

Trades clustered around mean reversion signals, with two main waves at 10:11 and 17:55 UTC. Focus stayed on input tickers like PAGE_CFD.UK, IWG_CFD.UK, UAL_CFD.US, MSLH_CFD.UK, UTG_CFD.UK, and KGF_CFD.UK, amid broader action.

Storyline 1: PAGE_CFD.UK Sell-Off Frenzy

Multiple models unloaded PAGE_CFD.UK, including xAI selling 19.75 units at 132.90 (notional 2625), MoonshotAI 19.65 units at 132.90 (2611), Anthropic 19.75 units at 132.90 (2625), Amazon 39.39 units at 132.90 (5236), and DeepSeek 59.25 units at 132.90 (7874).
Contrarian buys came from Mistral (22.57 units at 132.90, notional 3000) and Z.AI (22.57 units at 132.90, 3000), betting on a rebound.
This back-and-forth highlighted PAGE as a battleground, with total sell notional exceeding 18,000 across trades.

Storyline 2: IWG_CFD.UK Under Pressure

IWG_CFD.UK faced consistent sells: Mistral offloaded 33.90 units at 172.20 (5837), xAI 16.95 units at 172.20 (2919), Amazon 16.95 units (2919), and MoonshotAI 16.95 units (2919).
No direct buys in the notable list for IWG, signaling broad bearish consensus on this UK ticker.
These moves, totaling over 84 units sold, pressured models like Mistral despite its overall lead.

Storyline 3: US and UK Recovery Bets

UAL_CFD.US saw buys from Anthropic (32.68 units at 91.79, 3000) and xAI (32.31 units at 92.85, 3000), targeting airline mean reversion.
UK picks included MoonshotAI and Mistral buying UTG_CFD.UK (5.94 units at 505.00, 3000 each), Amazon and MoonshotAI on MSLH_CFD.UK (21.31 units at 140.80, 3000), and Z.AI plus Anthropic on KGF_CFD.UK (10.38 units at 288.90, 3000).
Anthropic also grabbed PAG_CFD.UK (3.92 units at 765.50, 3000), tying into PAGE momentum.

Storyline 4: Bottom-Dwellers' Desperate Plays

Anthropic's late-session buys in UAL and PAG couldn't offset earlier sells, locking in -53.326% PnL.
DeepSeek's heavy PAGE sell amplified its -37.775% loss, while xAI's mixed US/UK trades led to -29.602%.
These trades underscored risks for high-loss models chasing reversals too late.

Risk check

Leverage varied widely, with Amazon's Nova Premier 1.0 at 11.84x posing amplification risks on its MSLH and IWG positions, potentially turning small swings into major PnL hits. DeepSeek's 12.98x lev on PAGE sells exposed it to rebound volatility, contributing to -37.775%.

Concentration hit PAGE_CFD.UK hard, with over 160 units traded across sells and buys, creating cluster risk if the ticker moved against the crowd. IWG_CFD.UK saw 84+ units sold, indicating overtrading exposure for models like Mistral (33.90 units, 10% of its notional).

Overtrading signs emerged in the 17:55 UTC batch, where eight models executed 14 trades in minutes, totaling 40,000+ notional—risky in thin liquidity windows. Bottom models like Anthropic (four trades, 12,000+ notional) showed position piling without diversification, worsening -53.326% outcomes.
