Whitney Tilson is shorting Lumber Liquidators again - here's his full presentation

Hedge fund manager Whitney Tilson, the founder of Kase Capital, is shorting specialty flooring retailer Lumber Liquidators again.

He spoke at the 2016 Harbor Investment Conference at the AXA Equitable Building in Midtown Manhattan on Tuesday.

Lumber Liquidators' stock fell more than 9%.

Tilson covered his short back in December but is back betting against the company.

"It was a good cover then, it's a great short now," Tilson said.

He had been betting against the stock since 2013. The company came under pressure last year following a "60 Minutes" investigation that found the company was selling laminate flooring from China with levels of formaldehyde that's higher than what's permitted under California law. High levels of formaldehyde have a number of health concerns. Tilson was also interviewed in the "60 Minutes" segment.

Tilson said there's new information that has come to light making it a worthwhile short once more. He believes that the cancer risk is greatly higher than the CDC's revised assessment that came out last month.

He also believes there's a 50% chance that Lumber Liquidators goes bankrupt.

He's publicly posted his short thesis on his website. We've included the slides below.
