| META S1 | +2.76% | -0.21% | Signal was right and is the dominant factor. The short on the "$200B AI spend" headline predicted bearish, and META fell from 755.38 to 737.89 (–2.3%) while open, with worst drawdown only –0.21%, so the thesis played out almost immediately and cleanly. Timing was fine: at decision time the stock was only –0.36% from prev close, so the move had not yet happened; the fill at 755.38 (–0.93% vs. 762.50) means roughly half a percent leaked between decision and fill, but the bulk of the drop came after entry. Exit captured most of what was available: +2.32% realized against +2.76% best unrealized (~84%), leaving ~0.44% on the table — a minor give-back rather than a flaw. Whether the exit was a target, trail, or time stop isn't stated here, so I can't judge the exit mechanism itself, only that it was close to optimal. |
