Is A Stock Market Crash Like 2000 Possible?

Say say two thousand zero zero party over, oops, out of time
So tonight I’m gonna party like it’s nineteen ninety-nine”
-Prince 1999

Prince wrote the song “1999” in 1982, 18 years before the clock ran out on the 20th century and on possibly the greatest stock market run in American history.

In 1999, equity valuations stood at unprecedented peaks, even dwarfing those of 1929. At the time, investors were euphoric as if the rally were eternal. Newbies were killing it, and veterans were cleaning up like never before. Some stocks were rising 10, 20, and even 30% or more in a day. Companies adding dot com to their name or discussing new internet technology saw huge pops in their share prices. Investors bought the narrative with little to no due diligence.

Sounds familiar? Not only is today’s speculative environment eerily similar to the late 90s, but valuations, in many cases, are frothier than that period.

Comparing valuations from separate periods is inaccurate as economic and earnings environments can be different. This article contrasts the valuations and environments to consider if it’s time to leave the party or stay and rock on. To help you decide we provide a statistical analysis showing the potential downside risk facing the S&P 500.

First, however, let’s look at a few valuation measures to provide context between today and 1999.

S&P 500 Price To Earnings/h2

Price to earnings (P/E) is the most often used method to value stocks. It’s common for investors to use the trailing 12 months (ttm) of earnings in the P/E denominator, as shown in the first graph.

Some investors, including ourselves, prefer using the CAPE P/E. Robert Shiller’s CAPE method uses the last ten years of earnings to better factor in secular earnings trends and avoids one-off events that distort valuations.
