Investors who got a midsummer haircut last week during the Dow’s 735-point drop from 14,000 probably aren’t singing Happy Birthday for the Sarbanes-Oxley Act, which is 5 years old today. But maybe they should be.

If you think last week’s sell-off was bad, recall the summer of 2002. Enron had imploded, WorldCom admitted to fabricating billions of dollars in earnings, and prosecutors were swirling around Tyco and Adelphia. From May 24 of that year to July 23, the Dow dropped from 10,104 to 7,702, a plunge of 24%.

That wasn’t a haircut, or a correction. It was a full-blown crisis. The public, and even the White House, demanded action.

In response, Congress passed the Sarbanes-Oxley Act on July 30, 2002. The law forced public companies to spend much more money having their books thoroughly audited, and it increased the penalties for executives who defrauded investors. Since the bill’s passage and implementation, nervous investors who had yanked trillions of dollars from the market have returned.

USA Today: Sarbanes-Oxley law has been a pretty clean sweep
