What the stocks did next

For each trade, the change in the stock's price from the week of the trade to the same window later, and the same change minus the S&P 500 (SPY). For sales, a fall afterward means the stock was sold before a drop.

Weekly prices from SEC fails-to-deliver data; the S&P 500 is measured with the SPY ETF. Exact trade prices and amounts are not disclosed, so these are the stocks' moves, not the member's profit. Dividends are not included, and windows with a likely stock split are skipped. A move after a trade does not mean the trade caused it. Past results do not predict future ones.

Most traded stocks, with each trade marked

Green markers worked out (a purchase that rose, or a sale before a fall), red went against them, and hollow markers are purchases still held. Hover or tap a marker for the numbers.
