Summary
Bill Ackman's Pershing Square Capital disclosed a significant shift in its technology sector exposure during the first quarter of 2026, exiting a Google position while establishing a $2.09 billion stake in Microsoft. The hedge fund acquired 5.65 million shares at an average price of $370 per share, making this one of Pershing Square's largest Q1 investments. The entry point reflected Ackman's assessment of compelling valuation following a period of share price weakness in the software giant.
Since the February initiation of the position, Microsoft shares have traded in a wide range. The stock appreciated to approximately $460 in June 2026—the peak of the investment's life cycle—generating unrealized gains of $508.5 million at that juncture. However, the position has since encountered headwinds as Microsoft entered a bearish phase in June, declining more than 10% or roughly 45 points from its highs. At current trading levels near $378 per share, Ackman's position carries an unrealized profit of $45 million, translating to an $8 per share gain and a 2.2% total return across approximately six months of holding.
Despite the recent pullback, Ackman has publicly indicated continued conviction in Microsoft's prospects. His thesis centers on the company's artificial intelligence initiatives, particularly its Azure cloud platform and broader AI ambitions. The billionaire manager expects Microsoft to reclaim its June peak and advance further, which would restore the position toward triple-digit percentage returns. Market participants have echoed this sentiment, with several commentators describing Microsoft stock at current sub-$400 levels as a bargain, noting that institutional accumulation is underway as traders capitalize on the temporary dislocation.
The timing of this investment aligns with broader institutional rebalancing in megacap technology stocks and reflects confidence in Microsoft's secular growth drivers amid near-term volatility. Pershing Square's position sizing—representing material capital deployment—underscores Ackman's conviction in the thesis and the fund's commitment to technology sector exposure at present valuations.
