Stocks knocked it out of the park in April.

Wall Street’s April rebound ended the month with a scoreboard that looks more like 2020 than 2026 — and some of the details look even more like the dot-com era.

The S&P 500 (^GSPC) surged over 10% during the month, its best showing since November 2020, while the Nasdaq Composite (^IXIC) jumped more than 15% for its best month since April 2020. The Nasdaq 100 (^NDX) gained nearly 16%, its best month since October 2002.

That was not the setup investors had in mind a month ago, with stocks still shaking off the shock of a major war and the bull market suddenly on defense.

The rally was broad enough to pull smaller stocks along, too. The Russell 2000 (^RUT) climbed more than 12%, also its best month since November 2020.

But the S&P 500 equal weight index rose less than 6%, barely more than half the gain in the cap-weighted S&P 500. That gap shows how much of April’s rally still came from the biggest stocks, not the average one.

Technology did most of the heavy lifting. The Technology Select Sector SPDR Fund (XLK) gained 20%, its best month since October 2002.

Chips were the biggest reason.

The PHLX Semiconductor Index (^SOX) surged more than 40%, and had its best month since February 2000 — extending the record-setting semiconductor run that has been driving the AI trade. It logged a record 18-day win streak and rose 13 straight days to record highs.

That strength ran straight through the stock leaderboard.

Intel (INTC) posted its best month ever, adding to the breakout above its dot-com-era ceiling after earnings. AMD (AMD) had its best month since January 2001, while Micron (MU) and Texas Instruments (TXN) had their best months since February 2000.

The same concentration showed up in market value.

Alphabet (GOOGL) added roughly $1.2 trillion in April — posting its best month since 2004 — while Amazon (AMZN) and Nvidia (NVDA) each added more than $600 billion. Broadcom (AVGO) tacked on more than $500 billion.

The laggards told the other side of the story.

Energy (XLE) and health care (XLV) finished lower in April, while the software comeback that briefly looked promising ended up fading against the semis. The iShares Expanded Tech-Software Sector ETF (IGV) rose less than 5% and is down more than 20% for the year.

April put bulls back in control. The test in May is whether the average stock can start carrying more of the load.
