Absolutely incredible. Just 10 stocks have driven 70% of the S&P 500’s gain since March 30th. These stocks have added +16 percentage points to the index’s +23% gain over this period.
Nvidia has contributed the most, accounting for 13% of the S&P 500's gain, or +3 percentage points.
This is followed by Micron, Apple, and Microsoft, each accounting for 9% of the S&P 500’s advance, adding +2 percentage points.
Return contributions of AMD and Alphabet have been 8% and 7%, respectively.
Meanwhile, the remaining 490 stocks have accounted for just 30% of the S&P 500's gain since March 30th, adding +7 percentage points.
Diversification is dead.
