In this piece, we discuss the 10 Tech Stocks to Sell According to Billionaires.
Tech stocks have driven the market to the point where the S&P 500 technology sector now accounts for more than 39% of the index’s total market capitalization, its highest share on record and above the level reached during the 2000 internet bubble, according to a June 3, 2026, Reuters report.
Since the market’s March 2026 low, the tech sector has surged nearly 47%, more than double the S&P 500’s overall gain in that span, led by semiconductor names. Micron shares jumped 230% over that period, while Intel and Advanced Micro Devices each gained more than 160%. Matthew Maley, chief market strategist at Miller Tabak, warned that if the small group of tech stocks leading the rally falters, the broader indexes will follow, and the resulting money flows would inevitably reverse.
That concentration has left the market increasingly dependent on a narrow set of winners.
About 60% of S&P 500 constituents were trading above their 200-day moving averages as of early June 2026, below the roughly 73% level historically seen when the index hits new highs, according to Adam Turnquist, chief technical strategist at LPL Financial. David Lefkowitz of UBS Global Wealth Management noted that the largest companies are generating far higher returns than the average stock, and cautioned that portfolios should not carry too much exposure to the AI trade’s recent winners.
Against that backdrop, billionaires have been trimming stakes in several prominent tech names. With that, let’s jump to the list of tech stocks to sell according to billionaires.
Our Methodology
To curate our list for this article, we used Insider Monkey’s billionaire database, which tracks 107 billionaires and their holdings as of Q1 2026. Next, we identified tech stocks whose billionaire stakes declined more than 15% quarter-over-quarter (QoQ). We ranked the stocks in ascending order based on the QoQ decline in billionaire holdings.
Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Insider Monkey’s quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 599.2% since May 2014, beating its benchmark by 372 percentage points (see more details here).
