Elon Musk added 20% to Twitter’s worth in one day. Here are other assets he’s either sparked or sunk with his tweets

Twitter shares soared more than 20% on news that Elon Musk has bought a 9% stake in the company — the latest business entity to see its stock head for lunar orbit after the Tesla CEO has shown an interest.

Musk hasn’t tweeted about the purchase yet. News of the stake came via a filing with the Securities and Exchange Commission (SEC).

But Musk has had plenty to say about Twitter in the past, specifically about whether the company adheres to free speech patterns.

That has led some analysts to suspect he has more ambitious investment plans for Twitter.

“Musk could try to take a more aggressive stance here on Twitter,” Wedbush analyst Dan Ives told CNBC’s Squawk Box. “This eventually could lead to some sort of buyout.”
