华尔街已学会了“TACO交易”：特朗普发飙后做空美股，5天后反手做多

Group 1 - The core strategy known as "TACO trading" has emerged on Wall Street, where investors short S&P 500 futures immediately after trade threats from Trump and then go long five days later, yielding a 12% return since early February [1] - Other Wall Street institutions have developed similar strategies based on the cyclical pattern of Trump's trade policies, which oscillate between escalation and alleviation, creating opportunities to capitalize on investor panic [1][2] - The S&P 500 index experienced significant volatility, dropping over 10% after Trump's initial tariff announcements in March, but rebounded sharply when he eased some measures [2][3] Group 2 - Market reactions to volatility have changed, with investors now downplaying spikes in the VIX index rather than chasing them, indicating a shift in sentiment [4] - Despite ongoing tariff threats, the market has shown resilience, with the S&P 500 only declining about 3.4% from recent highs, suggesting a new normal in response to Trump's policies [4] - The options market reflects a lack of extreme bullish or bearish sentiment, indicating that Trump's tariff news no longer has the same shock effect as before, leading to a potential reshaping of trading strategies [5]
