The seven largest US technology stocks — Microsoft, Nvidia, Alphabet, Apple, Meta, Tesla, and Amazon — collectively lost approximately $2 trillion in market capitalization during June, erasing year-to-date gains and leaving the group in the red for 2025. The selloff follows a period of extreme concentration risk in US equity markets, where the Mag 7 had accounted for a disproportionate share of S&P 500 returns since 2023.
The move is notable given that underlying fundamentals for the core names remain strong. Nvidia posted 65.5% revenue growth YoY with a 55.6% net margin and $4.90 diluted EPS. Microsoft grew revenues 14.9% YoY to $281.7B with a 68.8% gross margin. Alphabet expanded revenues 15.1% to $402.8B with a 32.8% net margin. These are not distressed businesses — the selloff is a multiple compression story, not an earnings deterioration story.
The bull case rests on the idea that the June decline is sentiment-driven and macro-driven (rates, rotation, geopolitical noise) rather than fundamental, making it a potential entry point for names with durable earnings power and above-market growth. Nvidia in particular remains the infrastructure backbone of the AI buildout, and any pullback in its multiple while its earnings trajectory accelerates creates a gap between price and intrinsic value.
The bear case is that even after the drawdown, valuations for most of these names remain elevated on a historical basis, and a sustained period of higher-for-longer rates or a deterioration in AI capex spending could push multiples lower still. Concentration risk cuts both ways: the same institutional crowding that inflated prices can amplify the unwind.
Key things to watch: the pace of AI infrastructure capex from hyperscalers in upcoming earnings calls, any guidance revisions from MSFT or GOOGL on cloud growth, and whether the June selloff was driven by mechanical rebalancing or genuine institutional rotation out of tech. The next quarterly earnings cycle will be the real test of whether fundamentals can re-anchor prices.
