KEY POINTS
The S&P 500 closed at a record 7,022 on Wednesday as the Nasdaq extended its winning streak to 11 consecutive sessions, the longest run in history.
Fixed income ETFs captured 43% of all monthly inflows during the March selloff, showing investors rotated within the ETF structure rather than fleeing it.
AI-focused ETFs are recovering sharply as tech earnings validate the demand story, with TSMC's 35% revenue growth serving as the sector's clearest confirmation.
The S&P 500 closed at a fresh all-time high of 7,022.95 on Wednesday, and the Nasdaq Composite hit 24,016.02, surpassing its previous October 2025 record. For ETF investors watching the broader picture, the record close is only part of the story. The more important signal is what the flow data beneath it is revealing about where institutional conviction actually sits.
During the worst of the Iran conflict in March, US ETF assets fell 7% to $13.3 trillion on headline figures. But fixed income ETFs pulled in $50.8 billion in monthly inflows during that same period, capturing 43% of all flow despite the drawdown. Investors did not abandon the ETF structure under stress. They used it to rotate defensively into bonds, short-duration Treasuries, and energy-linked funds. That is exactly what the ETF wrapper is designed for, and it worked precisely as intended.
Now the rotation is reversing. As ceasefire optimism builds and the S&P 500 recovers its war-driven losses, AI and semiconductor-focused ETFs are seeing renewed inflows. The iShares Semiconductor ETF rose strongly following TSMC's blowout Q1 results reported Thursday, which showed a 58% jump in first-quarter profit and CEO C.C. Wei confirming that AI-related demand "continues to be extremely robust." When the world's largest contract chipmaker says conviction in the AI megatrend remains high, ETF flows into AI infrastructure funds tend to follow within days.
The energy sector ETFs that delivered above 35% returns in Q1 are now facing a different question: how much of the ceasefire-driven oil decline compresses their forward earnings expectations. The State Street SPDR Oil and Gas Exploration ETF entered the year trading at a forward PE of just 11, meaning the sector was cheap even before oil surged. At current oil prices near $95, earnings estimates remain elevated relative to historical norms. The unwinding of energy ETF gains will be gradual rather than immediate.
The broader structural story remains intact. VOO, Vanguard's S&P 500 ETF, is within striking distance of $1 trillion in assets, a milestone that would be the first in ETF history and a symbolic moment for a structure that has steadily displaced mutual funds as the vehicle of choice for both institutional and retail capital. The record market levels of this week put that milestone back within reach.
