Investors in Super Micro Computer, or Supermicro (SMCI), may have noticed that shares are trading lower today. No need to panic.

In other words, if Super Micro Computer shares were trading at $1,000 before the split, an investor holding one share before the split would hold 10 shares priced at $100 each after the split. (Companies can also hold reverse splits, as some have done lately .)

On Sept. 25, a group of 16 analysts had an average one-year price target on Supermicro stock of $729.19. That represents around 60% upside from the stock's closing price on Sept. 25, which was a day before a Wall Street Journa l article helped fuel a 12% drop.
