Full Analysis
Boston Scientific (BSX) stock has experienced significant volatility, losing over half its value in the past 12 months compared to the S&P 500's gains. Recent setbacks include a cyberattack in September that likely prevented the company from meeting its guidance, causing shares to drop an additional 8.8% while the broader market rose.

Management has reported slowing growth, with quarterly revenue growth falling from 20% three quarters earlier to 7.5% in the second quarter of 2026. On its July earnings call, leadership cut the 2026 organic revenue growth outlook to a range of 5% to 6%.
