According to The Kobeissi Letter, the Dow Jones Transportation Index experienced a significant drop of over 9% without the Volatility Index ($VIX) rising above 35, which is an unusual market behavior. Historically, such declines are typically accompanied by a spike in the VIX, suggesting potential market volatility. Traders should be cautious as this anomaly could indicate underlying market stress or impending volatility. Monitoring VIX and transportation sector performance is crucial for informed trading decisions.
