The Micron (MU) stock price bubble could best be explained — partially — by two simple numbers.
The quick analysis: Micron has become a major driver of the S&P 500’s (^GSPC) projected future earnings growth because of its strong outlook, Goldman Sachs strategists pointed out. It’s only second to AI chipmaker Nvidia (NVDA) in importance to the index.
Micron stands to represent 14% of the estimated 2026 EPS growth for the S&P 500 this year, based on Goldman’s analysis. That would be second to Nvidia’s 18%.

Alphabet (GOOG, GOOGL) is a distant third.
