Applied Materials Inc. (NASDAQ:AMAT) is the best-performing stock in the S&P 500 this month, surging about 54% in June.

It is a move with almost no precedent in the company’s history.

On Applied Materials’s monthly return record stretching back to the early 1970s, a single-month gain this large has happened only twice before — in January 1975 and May the same year.

That makes June 2026 the stock’s strongest month since 1975.
