Virgin Galactic's stock has more than tripled in the past three months, up 298% at the end of trading Wednesday.
Fidelity told CNBC that Virgin Galactic was bought more than any other stock on Tuesday — topping Apple, Tesla and others.
Virgin Galactic and Tesla have similarities that help explain why both are such popular speculative plays for investors.
Shares of Virgin Galactic shot up 23.3% in trading Wednesday to close at a new record high of $37.35, its highest ever finish and the stock's single best day of trading. This follows a 21% jump on Friday and 5% surge on Tuesday, daily trading spikes that resemble the speculative run in Tesla two weeks ago.
