The Biggest Secret of 2025

As futures open Sunday night at 5:00 pm CST (6:00 pm EST), the “Sunday night trade” has quietly become the biggest secret of 2025.

Go long on Sunday, exit before the open on Monday and play golf the rest of the week!

Year-to-date, the Nasdaq 100 index has gained 1,768.43 points. Remarkably, going long the Nasdaq 100 futures at 6:01 pm EST Sunday and exiting at 9:00 am EST Monday has captured 1,648.50 points—93% of that advance—in just a 15-hour weekly window, with very little adverse excursion relative to overall volatility.

By contrast, in 2024 overnight sessions every night accounted for over 100% of the index’s gains. This year, however, that opportunity has contracted to Sunday nights—emphasizing the market’s concerted, stealth rallies when most traders are asleep or least expecting them.

These findings underscore how net gains are becoming concentrated into ever-smaller windows of time. Is this “time divergence” a precursor to a topping pattern and a complete contraction on the horizon? Or will fresh liquidity continue to broaden trading horizons and fuel sharp rallies across both day and night sessions?

This is an example of an extreme inefficiency that I anticipate will change.
