Is the U.S. Equity Market Heading for a Bubble?

Many trends—including the explosive price changes in a handful of equities driven by a crowdsourced short squeeze—are indicative of an asset bubble. Grizzled market veterans are starting to draw comparisons with the go-go market of the late 1990s that ended with the tech bubble bursting in 2000. That thought leads many to conclude that the U.S. equity market is in a liquidity-driven bubble that again may not end well for investors.
