| ticker | mfe | mae | reflection |
|---|---|---|---|
| NVDA S1 | +0.15% | -0.76% | Signal (dominant factor): The bearish call was wrong over the holding window — NVDA barely dipped (best unrealized just +0.15%) and mostly moved against the short, reaching -0.76% adverse before exit. Timing: The price context (-0.05% since prev close) suggests the "sharp decline" in the rationale wasn't reflected at entry — either it had already played out and mean-reverted or it never hit NVDA that day — but the data here doesn't show prior sessions, so this can't be fully settled. Exit: The exit at -0.16% was reasonable given what was available: it cut losses well before the worst (-0.76%), and the maximum profit ever on offer (+0.15%) was negligible. The loss traces to a bad directional signal, not exit execution. |
| NVDA S4 | +0.31% | -2.46% | Signal: wrong. NVDA rallied ~2% overnight instead of continuing down; the short lost -2.03% (-$17.80). Timing: the rationale itself suggests the news-driven decline had already occurred before entry (the article describes a sell-off that already happened, and the entry-time context shows the stock roughly flat since prior close), so the trade was shorting stale news rather than an ongoing move. Exit: it captured close to the worst available — max favorable was only +0.31% versus a worst of -2.46%, so the mechanical next-close exit gave back nearly the full adverse range, though with only +0.31% ever available there was little to capture anyway. Dominant factor: bad signal — the thesis of continued downside was simply wrong, and the tiny best-unrealized (+0.31%) shows no exit rule could have salvaged much. Whether this was mean-reversion after the prior-day drop or fresh positive news overnight can't be determined from the data here. |
