A market research firm is warning that the S&P 500 could fall as much as 15% as persistent inflation pressures mount, potentially sending investors fleeing from stocks into bonds. Zweig-DiMenna Research issued the forecast Monday, saying the risk of a sharp correction is rising because the Federal Reserve may need to keep interest rates higher for longer than many expect.
The Warning
In a note to clients, the firm said the benchmark index could shed roughly 15% of its value if inflation doesn't cool fast enough. The drop would likely be driven by a reassessment of corporate earnings and valuations as borrowing costs stay elevated. Zweig-DiMenna did not specify a timeline, but flagged the scenario as a real possibility over the next several months.
A 15% decline would wipe out most of the S&P 500's gains over the past year. The index is currently trading near all-time highs, buoyed by artificial-intelligence hype and resilient consumer spending. But sticky inflation data has rattled bond markets, with the 10-year Treasury yield hovering near 4.5% in recent weeks. If yields climb further, stocks become less attractive relative to bonds, and the rotation out of equities could accelerate.
The firm noted that such a shift would hit asset valuations across the board, especially high-growth tech stocks that have led the rally. Companies with heavy debt loads could also feel the squeeze as refinancing costs rise.
Investors are now watching the next batch of inflation data, due out later this month, for clues on the Fed's next move. A hotter-than-expected reading would likely reinforce the bearish outlook from Zweig-DiMenna. The firm hasn't issued a revised forecast yet, but its warning adds to a growing chorus of analysts cautioning that the market may be priced for perfection.
