On Thursday, shares of electric-car maker Tesla (TSLA 0.08%) continued to rebound from their worst one-day sell-off on record earlier this week. The stock jumped as much as 8.9%, but as of 11:15 a.m. EDT today, it had settled to about a 6% gain.
The move higher on Thursday extends Wednesday's rally for the growth stock. Based on this two-day rebound, investors seem to believe that Tesla shares were oversold during a big sell-off on Tuesday, creating a buying opportunity.
Until Wednesday, Tesla was seeing significant selling pressure this month. The stock appeared to be taking a breather after a wild run higher. It had gained about 500% between the end of 2019 and Aug. 31 -- a move that seemed to persuade some shareholders that it was time to do some profit-taking.
But after the September sell-off worsened on Tuesday, when the stock slid about 21% in a single day, some investors appear to be aggressively buying shares.
While Tesla is still down 19% in September, investors should keep in mind that the growth stock certainly isn't cheap. The company trades at about 17 times sales, up from a multiple of about eight as recently as a few months ago and a multiple of three just last year. With the stock's valuation changing so quickly, continued volatility is almost inevitable.
