Hedge funds are currently placing record multi-billion-dollar bets against the US stock market, suggesting anticipation of a potential market downturn that could affect retirement savings nationwide, as per insights from Goldman Sachs data. Elliott Management has cautioned that speculative bubbles fueled by Trump's presidency may have catastrophic repercussions if they burst, as detailed by the Financial Times. Concerns have heightened following a substantial sell-off in prominent US tech stocks, notably Nvidia, which suffered a depreciation of almost $600 billion due to concerns about competition from the Chinese AI company DeepSeek. This shift in hedge fund strategies reflects a significant alteration in market sentiment, posing a threat to the financial stability of millions dependent on 401(k)s and pension funds.
