|---|---|---|---|
| AMZN S4 | +1.81% | -2.15% | Signal: wrong. The thesis was that the capex-guidance headline would push AMZN lower overnight, but the stock rose from the 247.98 fill to 251.53 at next close (+1.43% against the short), ending above the 249.24 prior close. Timing: the data is contradictory and doesn't settle it. At decision time the stock was ~251.8 (+1.03% from prev close), yet the fill printed at 247.98 — about 1.5% lower — so either the hoped-for drop occurred between decision and fill (meaning the short was entered after the move it was betting on) or something is off in the fill record; the journal doesn't say which. Exit: left the whole favorable move on the table. Best unrealized was +1.81% (~243.5) versus the realized -1.43%; the fixed next-close exit captured none of the intraday dip and closed near the worst (-2.15%). The dominant factor is the wrong direction over the holding window — the price did dip, but the strategy's close-to-close bet landed on the rebound. |
