This is a troubling trend. Many of you have been around the block and have seen the mistakes day traders and speculators made during the dotcom bubble. Based on Bloombergโ€™s reporting, it sounds like a new crop of investors is likely to learn that when you treat the stock market like a casino, the house usually wins. Sarah Ponczek writes:

Back on March 23, it seemed like stocks would never stop falling. Congress was struggling to pass stimulus, coronavirus cases were climbing, futuresย were pinnedย to their bottommost tick andย $10 trillionย in value had vanished.

Meanwhile in Northern Virginia, Nicole Kelleher was opening her very first brokerage account. Little did she know, the S&P 500 was about to surge 30%.

The romance novel writer and administrative aide at George Mason University spreadย $5,000 across Peloton Interactive Inc., Fitbit Inc., Trivago and Dropbox Inc., among others, on the Robinhood Financial app. Her husband, a restaurant executive, told her she needed some real estate. So Kelleher bought shares of MFA Financial Inc. Five weeks later, the portfolio is up almost 12%.

On their own, Kelleherโ€™s purchases donโ€™t amount to much. But combined with similar decisions by tiny investors around the country, the buying represents a formidable force that has helped the market claw back more than half the ground lost in its fastest bear-market drop. A trio of giant retail brokerages, E*Trade Financial Corp., TD Ameritrade Holding Corp., and Charles Schwab Corp., each saw record sign-ups in the three months ending in March, with much of it coming at the depths of the swoon.

โ€œIโ€™m a complete noob when it comes to stocks,โ€ the mother of high school senior twin boys said while sheltering at home. โ€œItโ€™s not thousands and thousands of dollars that I invested, but itโ€™s a start. Weโ€™ll see what happens. I hate to say it, but itโ€™s like gambling, isnโ€™t it?โ€

There may be something to that. โ€œWhen the casinos/sport betting closed down, some of that action when to stock markets,โ€ speculated Nicholas Colas, cofounder of DataTrek Research, in a note Wednesday. โ€œGoogle Trends data supports that idea.โ€
