As investors cheer on the Magnificent 7, some football fans are forging new allegiances in hopes of rooting for the coming Super Bowl champion. The task isn’t easy.

Recent favorites like the Bills and Bengals are fighting to make the playoffs. Indeed, a few fans of those teams will jump on the recently popular Dolphins or Lions bandwagon. Others may stick with the dependable Eagles, Chiefs, and Forty Niners.

Stock market investors and football fans are not that different. As 2023 ends, professional and amateur investors start thinking about what stock or investment theme bandwagon to jump on for the coming year.

This year, the Magnificent 7 stocks are the odds-on favorites to win the stock market Super Bowl. While hats off to those profiting from the Magnificent 7, we must look ahead. To do so, we must appreciate the bandwagon bias harbored in our mindsets and not let it cloud our vision of the future.

Bandwagon Bias Of 2023/h2

Bandwagon bias is a psychological phenomenon that happens when people do something because others are doing it already. Often called following the herd in market parlance, the bandwagon bias forces many investors into decisions they ultimately regret.

This year’s most popular investment bandwagon is the Magnificent 7, comprised of Apple (NASDAQ:AAPL), Microsoft (NASDAQ:MSFT), Google (NASDAQ:GOOGL), Tesla (NASDAQ:TSLA), Nvidia (NASDAQ:NVDA), Amazon (NASDAQ:AMZN), and Meta (NASDAQ:META).

The graphs below, courtesy of Goldman Sachs (NYSE:GS), and our table show these 7 stocks gained 71% this year to date, while the remaining 493 stocks added a mere 6%. The outperformance pushed up their contribution to the S&P 500 to nearly 30%. Lastly, the sharp increase in stock prices led to even more extreme valuations for the group.
