1. Executive Summary
YM Macro Review for May 2026
During May 2026, the Dow Jones benchmark gained +2.86% while our YM strategy returned +1.12%, underperforming the index as equity markets rallied on expectations of Federal Reserve policy easing following softer-than-expected inflation data mid-month. The strategy's defensive positioning limited participation in the late-May risk-on rally, particularly as geopolitical tensions in Eastern Europe showed signs of de-escalation toward month-end, further boosting investor sentiment. Despite the relative underperformance, the strategy maintained lower volatility during the month's initial selloff early in May before markets reversed course on the shifting monetary policy outlook.
Signal Performance Overview for May 2026
Trailing 12-month Sharpe 0.89 and return 3.75% (through the period in Table 3 below). During the report month, the Dow Jones benchmark rose approximately 2.86%; the strategy returned +1.12% over the same window. The risk profile remained remarkably stable with maximum drawdown unchanged at -3.58% while the win rate showed modest improvement, increasing by 56 basis points to 53.48%. This period demonstrates consistent risk management with slightly enhanced trade execution efficiency compared to the previous 12-month window.

2. Trading Strategy
In order to produce the metrics below we use the signal in combination with the trading strategy below:
- Leverage: No leverage is applied for this strategy and metrics
- Positions:
- Entry positions: Every 5 minutes (between 09:45 and 15:30 ET) we decide to take a long, short or no position using 1/70 of our starting portfolio for the day (there are 70 possible openings per day). Each long/short position is then split into 5 parts and executed on each minute for the next 5 minutes following the decision. There is no sizing adjustment.
- Exit positions: We exit all positions at the end of the day. The exits are split over five minutes (15:55–16:00 ET).
- Costs: 1.5 bp round-turn assumption. Extra exchange/clearing fees not included.
- Contract series & roll: Front-month continuous. Switch at the open T–5 trading days before expiration; stop trading the expiring contract and start trading the next.
