Ball's prior trades at SI showed negative 90-day outcomes (-20.0% on 2025-09-12 and -16.9% on 2025-09-11), and his cross-ticker track record across 2 prior buys averaged -2.1% over 90 days with a 0.00% win rate, offering no historical validation of buy-side timing accuracy. The current trading price of $14.45 is now 2.8% below Ball's blended purchase price of $14.86, suggesting the market has not yet validated this accumulation within days of execution.
