The Invesco QQQ ETF, which tracks the Nasdaq 100 index, has crashed this year and moved into a correction after falling by over 12.8% from its highest level this year. It plunged to a low of $471, its lowest level since September last year.

Wall Street is an emotional place, which is really what makes markets work. However, every so often, investors flow like lemmings in just one direction. That happens during bull markets and during bear markets.
