Beyond Meat's post-IPO boom earns its first big skeptic

A Burn Book hall of famer... Shares of Beyond Meat fell 4% Friday after getting the attention of famous hater Citron Research. The hedge fund's core business strategy is betting against a company's stock and making money if the price falls. Its latest target is the plant-based "meat" company that just IPO'd. The shade was summed up in Citron's tweet:

"Beyond Meat has become Beyond Stupid" — @CitronResearch

Fake meat, real blood... Citron thinks Beyond Meat is over-valued. So it borrowed stock of the company in order to sell it at today's high price. Then it hopes to buy it back cheaper when the price falls. The difference between those two prices = profit (that's called "shorting a stock"). Here's what Beyond Meat's stock has done so far:

• The IPO price on May 2 was $25.
• The pea-protein food-maker's stock surged 163% on Day #1 to $65.
• By Friday, shares had climbed all the way to $87.
• Citron thinks they'll fall back to $65 after Beyond's first earnings report, as hype from meat-minimizing reducetarian Millennial investors dies off.
