10 Hottest Mega-Cap Stocks So Far in 2025

5. Boston Scientific (BSX)

• YTD Total Return: 7.58%

Boston Scientific (NYSE:BSX) makes medical devices. One of their most notable achievements was the development of a special device used to open clogged arteries in the heart called “Taxus Stent.”

I’m broadly bullish on most big-cap medical companies in the long run due to demographic trends, and that bullishness extends here, though I do think you should be careful in the near term as BSX has been trading at nosebleed levels. The stock is up 59% in just the past year and trades at 39 times forward earnings.

Recently, Boston Scientific (NYSE:BSX) announced an agreement to fully acquire Bolt Medical, which develops a laser-based technology known as intravascular lithotripsy (IVL). This technology helps break up calcium deposits in arteries and restore healthy blood flow. The deal is valued at up to $664 million (including milestone payments) and is expected to be finalized in the first half of 2025.

On the financial side, the company reported strong third-quarter 2024 results, with net sales of $4.209 billion — a 19.4% increase year-over-year on a reported basis — driven by sales growth in both its MedSurg and Cardiovascular segments.
