Is Boston Scientific Stock Riskier Than It Was A Year Ago?

Investors in Boston Scientific (BSX) hold stakes in a medical device maker that grew revenue 13.5% over the twelve months to June 2026. Yet the shares have lost 54.7% over the past year, trailing a 17.3% gain for the S&P 500. In August, a cyberattack disrupted the company's manufacturing and order shipments. So has the risk in holding Boston Scientific shares gone up or down over the past year.
