The official numbers are now in and more than 38 million shares of Tesla (Nasdaq: TSLA) were in the hands of short sellers as of April 13, 2018. That’s a whopping 10 million shares picked up by shorts in just one month’s time and a strong indication that TSLA short interest topped 40 million shares later in the month. To put the numbers in perspective, TSLA shares held by shorts during the past 12 months have previously ranged from 27 million shares to a bit over 31 million. Even with those lower numbers, TSLA managed to sometimes hold the title of the most shorted stock in the USA! Above 38 million shares, though, that means that more than 30% of Tesla’s tradable shares are in the hands of entities that are betting the stock will lose value. The track record of those who bet against Elon Musk is not good, particularly when the number of shares sold short reaches such epic heights.
