| QCOM S1 | +0.44% | -1.46% | The entry treated a "considering" headline as a repricing event, but speculative policy chatter with no concrete action rarely moves a name durably — QCOM never dropped meaningfully (max favorable move just +0.44%) and drifted against the short for a -1.46% worst drawdown before exiting at a loss. The rationale conflated headline severity with price impact; nothing in the trade confirmed the market was actually repricing. Concrete fix: require confirmation before assigning REPRICING to regulatory news — e.g., only trigger on enacted/announced actions (not "considering/weighing" language), or demand the stock already be down >1% on the headline before shorting; otherwise downgrade the verdict to WATCH. |
| QCOM S4 | +5.07% | -2.69% | Entry vs. outcome: The short thesis (China export-control headline risk) actually worked — the position was up as much as +5.07% while open — but the rigid "exit at next close" rule let the entire gain evaporate into a -$9 loss when the stock reversed. The failure here isn't the signal, it's the exit mechanics: headline-driven moves on speculative regulatory news ("is considering") tend to mean-revert fast once no concrete action follows. Concrete improvement: Add a take-profit override to the hold-to-close rule — e.g., exit intraday if unrealized gain exceeds +3%, or trail a stop at 50% of peak unrealized profit. Alternatively, tighten the entry verdict to require confirmed regulatory action rather than "considering" language, since vague headlines produce exactly this spike-and-fade pattern. |
