BSX versus the market
BSX's typical 3-month return moves 1.6 times as much as the S&P 500's from one regime to another (BSX +1.2% to +7.9%, S&P 500 +1.7% to +6.0%).
Today's reading: 17th percentile (0 most Risk-Off, 100 most Risk-On), as of Friday's close, Oct 16.
Unlike the market, BSX's weakest regime has been Mildly On, not Mildly Off. BSX has historically shared the market's bounce from Risk-Off.
How to read this
Base rates, not forecasts. These describe what BSX did after past days in each market regime. They are not forecasts: any single period can land far from the typical return, and a pattern from the last two decades may not hold in the years ahead.
The numbers. The typical return is the median: the middle outcome, with half of past periods better and half worse. The usual range holds 8 in 10 of them, from the 10th to the 90th percentile. Past periods are counted only when they do not overlap. Limited history means 10 to 14 such periods, shown in italics; too little history means fewer than 10, shown as a dash. BSX history from January 3, 2006, data through October 16, 2026.
About the same. The sentence under the title sets BSX's typical return in today's regime against its typical return across all markets; figures within half a point, or within a tenth of the larger one, count as about the same. The section on BSX versus the market sets how far its typical return moves across regimes against the S&P 500's move, which says nothing about better or worse overall.
Single stocks. For one stock the regime is usually a small nudge, not the main driver; its own trend dominates. Use it as context, not a reason to act. Why the mild-stress Dead Zone has been the weakest place to be.
