> The index gained 23% over that period, while 84% of its stocks remained at least 10% below their individual record highs.

The S&P 500 has gained 23% since its March 30 low, with 10 stocks supplying about 70% of the increase. Their contributions totaled 16 percentage points, while most index constituents remained well below their own record highs.

As of Oct. 15, Nvidia was the largest contributor, adding three percentage points, or 13% of the index’s total gain. Micron, Apple and Microsoft each added about two points. AMD contributed 8% of the advance, and Alphabet contributed 7%. The other 490 S&P 500 stocks together added seven percentage points, the remaining 30% of the gain.

The index’s rise contrasts with the distance many of its stocks remain from their individual peaks. Eighty-four percent of S&P 500 stocks were at least 10% below their own highs. Fifty-nine percent were at least 20% below those peaks, 41% were more than 30% below and 17% were more than 50% below. These figures compare each stock with its own high, while the 23% gain measures the index’s change since March 30.

The S&P 500 posted 52% blended earnings growth in Q2 2026, its fastest pace since Q2 2021. That earnings measure provides a separate view of corporate performance during the period; the return figures show how unevenly the index’s advance was distributed among its constituents.

Interest-rate expectations shifted over the same broader period. At the start of 2026, markets anticipated at least three rate cuts totaling 75 basis points. As of Oct. 15, 2026, the Federal Reserve had raised rates once during the year, and markets expected three more increases by June 2027. Including the September increase, the expected total tightening was 100 basis points, a 175-basis-point swing from the earlier cuts outlook.

Despite the narrow contribution to its rebound and the changed rate outlook, the S&P 500 remained about 2% below its record high. The figures put the index’s headline performance alongside the weaker readings across many of its individual stocks.
