Late-Stage Mania: “The Worst Thing Ever”

Learn more about this firm

Recently, we had dinner with some of our grandchildren and they ordered macaroni and cheese. The recent advertisement goes, “Kraft Mac and Cheese, the best thing ever!” For most investors in the stock market, the S&P 500 Index has been the best thing ever over the last 17 years and terrific since the bottom of the stock market in 1982. History would argue that investing in popular securities and heavily concentrated versions of the S&P 500 over history has been the worst thing ever for investors!

Here are some of the most concentrated markets in the past two centuries:

Some of the worst market declines in history have occurred in our 45 years in the stock market (1987, 2000-2003, 2007-2009 and 2020). However, the 1987 and 2020 declines lasted just 78 and 60 days and fully qualify as cases of fast death. The other two were 50% declines in the S&P and, in 2000-2003, included NASDAQ annihilation. Nobody survived the 85% decline in Amazon’s stock from December 27, 1999, to the bottom in 2003. Therefore, since 1981, when long-term Treasury interest rates peaked at 15%, the S&P 500 Index has had a massive tailwind from the reduction in the risk-free interest rates. Cheap stocks in 1982 and constantly declining interest rates were the BEST THING EVER!

Where are we now? Interest rates are rising, and probably the only thing that would bring those interest rates down would be a massive sell-off in the S&P 500 Index. Why do we say that? We say it because that is where the money is, and it won’t move to safety until the Index gets slaughtered. The Index will get slaughtered because it is massively over-weighted in technology and tech-related stocks to the tune of 50%.
