Bullish market timer Tom McClellan turns bearish after NYSE sees over 1,000 net decliners.

Tom McClellan, editor of the McClellan Market Report, switched from a bullish to a bearish outlook after the NYSE recorded more than 1,000 net decliners on Monday, far exceeding his threshold of 241. This shift comes despite the S&P 500 and Nasdaq-100 recently hitting record highs. McClellan's change signals caution for investors as the market shows signs of potential weakness following a broad pullback in stocks.
