March 12 is likely to be added to every finance 101 textbook that's printed going forward, with both the S&P 500 and Dow Jones Industrials falling close to 10%, and the Nasdaq Composite barely missing that painful decline, losing "only" 9.4% on the day. Investors haven't suffered through a day this bad since the 1987 crash. Even during the worst of the global financial crisis just over a decade ago, stocks never came close to falling so sharply.
And as bad a day as it was for the entire market, some individual stocks had it even worse: Appian (NASDAQ: APPN), New Relic (NYSE: NEWR), Paycom Software (NYSE: PAYC), Pegasystems (NASDAQ: PEGA), and Upwork (NASDAQ: UPWK) all finished the day down between 12% and 14% in very heavy selling.
