The sale occurred near RMBS's 52-week high of $68.59 and $2.69 above the current price of $66.33, positioning this trade at an inflection point after a strong 21.7% 90-day run and 7.1% 30-day appreciation. Across his open-market history spanning multiple tickers, Fan's 6 prior sells averaged -12.2% 90-day returns with a 100.00% well-timed rate, and at RMBS specifically, 2 of 2 measurable prior sells posted negative 90-day outcomes (-14.9% and -9.5%).
