Why Did BSX, LI, BJ Stocks Hit 52-Week Lows Today?

• Boston Scientific CEO Michael Mahoney said standalone Watchman procedures weakened in 2026.
• Analysts expect Li Auto to post a quarterly loss as competition in China's EV market intensifies.
• BJ’s Wholesale Club faced pressure as investors worried about weaker near-term earnings and softer fuel profits.

Boston Scientific (BSX), Li Auto (LI) and BJ’s Wholesale Club Holdings (BJ) each tumbled to new 52-week lows on Wednesday as investors moved away from companies facing mounting spending demands and weaker near-term profitability.

The drop across healthcare, electric vehicles and retail showed investors are now favoring companies with steady profits and strong demand instead of businesses that need heavy spending to keep growing. 

While Boston Scientific stock plunged 12% on Wednesday, Li Auto and BJ’s Wholesale Club stocks finished the day 0.6% and 0.8% lower, respectively. 

BSX’s Implants Business Under Pressure 

Boston Scientific stock hit a two-year low of $50.04 as investors reacted negatively to CEO Michael Mahoney's acknowledgment of weaker usage trends for standalone Watchman procedures in 2026.

Speaking at Bernstein's annual conference on Wednesday, Mahoney explained that physicians are increasingly combining Watchman implants with other cardiac procedures during a single hospital visit instead of scheduling them separately. 

That shift in treatment patterns has reduced growth in standalone procedures, creating pressure on quarterly sales momentum.

Also, Stifel reduced its price target on the medical device company to $75 from $85 while maintaining a ‘Buy’ rating, noting that the company’s Watchman business continues to face pressure from slowing standalone procedures.

However, on Stocktwits, retail sentiment around the stock jumped to ‘extremely bullish’ from ‘bearish’ territory the previous day. 

LI Faces EV Margin Pressure

Li Auto’s stock reached a 52-week low of $15.3 ahead of its fiscal first-quarter (Q1) earnings on Thursday. The company is bracing for a quarterly loss, with analysts forecasting a RMB2.08 ($0.31) per-share loss, a reversal from last year’s profit as Li battles China’s competitive EV landscape. 

Ongoing price cuts in China’s EV market have hurt car prices and profits. Investors also said foreign tariffs and rising manufacturing costs have made Li Auto’s transition plans more difficult.

Also, the company delivered 34,085 vehicles in April, a 17% decline from March. Retail sentiment around the stock turned to ‘bullish’ from ‘bearish’ territory the previous day. 

BJ’s Wholesale Navigates Consumer Slowdown

BJ’s Wholesale Club also faced selling pressure after investors questioned the retailer’s near-term earnings outlook. The warehouse chain has been dealing with softer fuel-related profits while continuing to spend heavily on store expansion and digital investments.

On Tuesday, DA Davidson reduced its price target on BJ to $105 from $114 while maintaining a ‘Buy’ rating after the retailer’s fiscal first-quarter (Q1) earnings report sparked investor concerns about merchandise margins and pricing pressure.

BJ’s Q1 merchandise margins experienced a 10-basis-point decline. Retail sentiment around the stock remained in ‘extremely bullish’ territory. 

So far this year, LI and BJ stocks have tumbled over 6%, while BSX stock plunged 47%.
