Beyond Meat (BYND) is now probably the hottest stock in the world.

Its innovative “plant-based meat” is found in the frozen food section of thousands of grocery stores. Carl’s Jr., Del Taco, and a few other restaurant chains sell its products, too.

Supposedly, it tastes just like real meat but is better for animals and for the environment. Many investors expect plant-based meat to be the “next big thing.”

The chart below says it all.

Beyond Meat’s stock shot up 840% after going public on May 2! Today In: Money

I’ve never seen anything quite like this. It’s the top-performing IPO of the year and one of the best of all time.

Make no mistake, Beyond Meat’s crazy 840% gain in not even three months is an outlier. But it’s not all that uncommon for stocks to skyrocket shortly after going public. The average return for a US IPO last quarter was 30%.

Get into the right IPO or disruptor stock (find our top picks for 2019 here), and you can realistically make huge gains within weeks, sometimes days.

But with the giant early gains in Beyond Meat behind us, the question now is: Does the stock have staying power? Should you buy it now?

Let me explain why the answer is NO.

Do You Remember the LaCroix Craze?

LaCroix is a popular brand of flavored sparkling water.

You’ve probably seen it at the grocery store. Its “retro” packaging jumps off the shelf.

It tastes pretty good, but it’s nothing special. There are plenty of sparkling water brands that are just as good.

And yet, LaCroix became a cultural phenomenon a few years back. Young adults were obsessed with it.

Like Beyond Meat, people thought it was the “next big thing.” Investors loaded up on shares of National Beverage (FIZZ)—the parent company that owns LaCroix.
