Pharmaceutical company Valeant reported fourth quarter earnings this morning, and it did not go well.

The company cut its guidance in a statement, and then cut it again on a conference call. It missed big on revenues for its blockbuster drug Xifaxan. Wall Street analysts questioned the credibility of management.

The stock is down around 45% at the time of writing, hammering a group of hedge funds which have stood by the stock.

Bill Ackman, the billionaire investor and long-time Valeant supporter, is down more than $600 million on paper today alone. Trading in Pershing Square Holdings, his publicly traded vehicle, was halted for a period.

Ackman responded by publishing a letter to investors saying, among other things, that the “underlying business franchises that comprise Valeant are worth multiples of the current market price.”

In non-Valeant news, Jefferies published an ugly set of first quarter results which hinted at improved trading conditions in recent weeks.

One of the top hedge funds of 2016 is betting on a crisis that blindsides everyone, and these 10 short-sellers had ideas that crushed it.

Lastly, Grenson, a 150-year-old English shoemaker, just opened its first overseas shop in New York City.
