1. Executive Summary
6J Macro Review for June 2026
The 6J benchmark declined approximately 1.30% over June 2026, as the Japanese yen came under renewed selling pressure amid a divergence in monetary policy direction (the Bank of Japan remained cautious and effectively on hold despite earlier market expectations of further tightening, while the Federal Reserve signalled a more gradual easing path than anticipated, keeping the dollar broadly supported against the yen). Geopolitical uncertainty in the Asia-Pacific region, alongside month-end rebalancing flows that favoured dollar strength, contributed to a late-month leg lower in the yen that accounted for a meaningful portion of the benchmark's drawdown. Against this backdrop, the strategy navigated the period defensively, returning +0.07% and largely sidestepping the month-end sell-off through reduced directional exposure.
Signal Performance Overview for June 2026
Trailing 12-month Sharpe 0.988 and return 3.045% (through the period in Table 3 below). During the report month, the 6J benchmark declined approximately 1.30%; the strategy returned +0.07% over the same window. Drawdown remains contained at -1.96%, unchanged from the prior window, reflecting consistent capital preservation discipline. Win rate has nudged higher to 59.95% from 58.02%, suggesting a modest improvement in trade selectivity and directional accuracy relative to the previous period.

- Entry positions: Every 5 minutes (between 09:45 and 12:00 ET) we decide to take a long, short or no position using 1/27 of our starting portfolio for the day (there are 27 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.
