Applovin

Revenue hit 1.9 billion dollars this quarter, up 53 percent from a year ago. Profit grew even faster, jumping 55 percent to 1.27 billion dollars. When sales climb fast and profits climb faster, it usually means the business is getting stronger with size, not more expensive to run.

AppLovin keeps roughly 64 cents of every dollar it collects as profit, which is rare for any business. They also generated 863 million dollars of spare cash in a single quarter and used 551 million of it to buy back their own shares. That leaves fewer shares outstanding, so each remaining one owns a bigger slice.

The company is worth about 140 billion dollars, which builds in years of flawless execution. Their own forecast calls for around 2.07 billion dollars next quarter, so growth is expected to keep sprinting. Any quarter that merely meets expectations instead of crushing them can knock the stock down hard.

This stock swings roughly two and a half times harder than the overall market. Its research spending more than doubled to 100 million dollars this quarter, a sign they must keep sprinting to stay ahead of rivals and platform rule changes from Apple and Google. Expect big drops along with the big gains.
