From 3 p.m. to 5 p.m. ET today, the Motley Fool BIG Short team will be hosting a live chat -- click below to join us!

The S&P 500 index has skyrocketed nearly 70% from its 2009 lows.

Yet John Del Vecchio, CFA -- one of the nation's leading forensic accountants and shorting experts -- believes corporate earnings quality is at its lowest level in decades. Meaning that many of these gains weren't merited.

He's even gone so far as to question the sustainability of giants like General Electric and IBM.

Whether or not you currently short stocks, now's a great time to consider using this tactic both to hedge your long positions as well as to profit from corporate accounting shenanigans.

Today, you can chat live with Del Vecchio to learn more about his shorting strategy. You'll have free reign to ask him about the basics of shorting, particularly how to use them in a currently long-only portfolio, as well as specific accounting shenanigans he looks for.

Just keep in mind the following ground rules:

  • John and the rest of the Motley Fool BIG Short team are not permitted to provide personalized investment advice.
  • The Motley Fool's editorial staff will moderate the discussion to make sure it stays on track.
  • John and his team may own stocks that are being discussed during the live chat. To see the stocks they own, view John's and Matt's profile pages.
