BSX
Underperforming without a clear catalyst yet
- BSX −1.46% on the last session vs SPY +0.74%: −2.2 pts of stock-specific move.
- Aftermath, 52-week low (Oct 2): After its 5 new 52-week lows in the past 5 years, BSX typically gained 1.1% over the next day (median) and was higher 60% of the time; half the outcomes fell between -0.6% and +1.1%. An ordinary day: +0.1%. Among S&P 500 stocks after new 52-week lows, that ranks #46 of 272. (Low confidence: few independent periods.)

- Market backdrop (Fri): Average Hourly Earnings m/m 0.1% vs 0.3% expected (cooler); Non-Farm Employment Change 29K vs 89K expected (weaker); S&P futures +0.41%, 10-year yield -5bp in the 30 minutes after.

The same event split by where BSX stood against its 200-, 50- and 20-day averages when it happened (a dip in an uptrend vs a falling knife); "vs" is the plain any-day median in that trend; "now" marks where it stands today. Splitting halves the evidence, so watch the confidence letters: H / M / L.

Aftermath: entry is the close of the first session the event was fully known (the same session for price moves, the reaction session for earnings, the next session for Reddit, analyst and insider events, which are dated by day). Repeats within a few sessions count as one event. Past performance after an event says nothing certain about the next one. Not advice.
