Micron and Nvidia Are the 2 Biggest Drivers of S&P 500 Earnings Growth. Are Their Stocks Buys?

October 21, 2026 · by TPW Pipeline

Two chipmakers are carrying an unusual share of the market’s profit growth. In its Oct. 16 Earnings Insight report, FactSet listed Micron Technology (NASDAQ:MU) and Nvidia (NASDAQ:NVDA) as the two biggest contributors to year-over-year earnings growth for the S&P 500 (SNPINDEX:^GSPC) in the third quarter of 2026.

FactSet’s blended growth rate of the index, which mixes reported results with estimates for companies yet to report, is at 29%. Without Micron and Nvidia, it would drop to 20%. Said another way, two companies are providing about 9 percentage points of the growth in an index of 500.

Their stocks have been moving the other way. As of this writing, Nvidia shares are around $217 and have lost 9% since their Oct. 6 record close. Micron is near $905, about 25% below its June 25 record close of $1,213.56.
