shorting a stock before making public pronouncements which are likely to result in losses in that stock's value. Cuban insisted that the practice is legal in view of full disclosure.

As of May 2015, he has invested in 85 deals across 111 ''Shark Tank'' episodes, for a total of $19.9 million.
In 2022, Cuban stated that his portfolio of ''Shark Tank'' investments had made a net loss, saying "I've gotten beat".
The actual numbers may vary because the investment happens after the handshake deal on live television and after due diligence is performed to ensure the accuracy of the information presented in the pitch room.
For instance, Hy-Conn, a manufacturer of fire hose adapters, after agreeing to a deal of $1.25 million for 100% of the company with Cuban, did not go through with the deal.
Cuban's top three deals, all with at least $1 million invested, are

The lawsuit was dismissed in 2011, due in part to Cuban asserting proper management of the team due to its recent victory in the
2011 NBA Finals. In 2014, the
