Tech Stocks Rebound Amid AI-Bubble Concerns, but Hidden Debt Looms

Investors recently pulled back from technology equities after worries that rapid AI-related spending could create a speculative bubble. The apprehension triggered a broad sell-off across U.S. and Asian tech indexes, pressuring even the sector’s heavyweight names.

In the ensuing weeks, chipmakers Samsung and Taiwan Semiconductor Manufacturing Co. (TSMC) posted strong price recoveries, lifting semiconductor-focused benchmarks in South Korea, Taiwan and China. While the exact percentage moves were not disclosed, the rally was described as “big gains” from comparative lows.

A separate concern emerged from financial disclosures by Alphabet, Amazon, Meta, Microsoft and Oracle. Nikkei reported that these firms collectively carry $1.65 trillion in off-balance-sheet debt—a figure that is eight times larger than four years earlier. The companies argue that projected earnings will eventually outpace these obligations, but the scale of the liability has drawn market attention.

Both Morgan Stanley and Moody’s issued reports flagging the swelling hidden debt as a risk factor for the sector. Their analyses note that while earnings growth may offset the liabilities over time, the sheer magnitude has begun to “show concern” among investors. The reports underscore the tension between optimistic revenue forecasts and the mounting financial commitments required to expand data-center capacity.

The juxtaposition of a price rebound with escalating hidden liabilities creates a nuanced outlook. Short-term optimism, driven by semiconductor demand, may be tempered by long-term balance-sheet pressures on the largest AI-focused firms. Analysts suggest that investors will monitor earnings trajectories closely, weighing the potential for continued upside against the risk that debt levels could constrain future profitability.
