Kyle Ash snapped up £2,000 ($2,615) worth of Twitter Inc. shares as soon as he heard that Elon Musk had become the social media company's largest shareholder.

The 25-year-old retail worker from Reading, Britain, bought into Twitter on Monday after shares surged 27% on news of Musk's investment in the San Francisco-based company.

Ash paid $49 per share on average, versus the $44 price target from analysts covering Twitter's stock. Bullish bets that go against Wall Street's conventional wisdom have been a hallmark of the "meme" stock trading frenzy that has swept many individual investors in the past 15 months.
