The number of bearish stocks on Twitter are approaching the level recorded at the January lows for the S&P 500 Index (SPX). They're now above their readings of last October. This is unusual given SPX is near all time highs so it's something you'll want to track carefully over the next few weeks. If the bearish stocks continue to rise it will warn of rising risk in the market. If Twitter Breadth falls below zero it will signal a change from bullish to bearish over the long term. You can see the current chart here. Here are some other things I'm watching that indicate weak stocks are being sold en masse.
