TESLA DISCLOSES $1.5B INVESTMENT IN BITCOIN

Tesla (TSLA) said in a Securities and Exchange Commission filing Monday that it bought $1.5B worth of bitcoin and that it plans to begin accepting it as a form of payment for its products in the near future. This comes amid a couple of positive messages about digital currencies by CEO Elon Musk on Twitter. Commenting on the investment, Wedbush analyst Daniel Ives called it a "major move" that will have a "ripple effect across corporations around the globe.”  The news formalizes the strategy of Musk and Tesla diving into the deep end of the pool of bitcoin and crypto, Ives added. From a stock perspective, the analyst believes this move could put more momentum into shares of Tesla as more investors start to value the company's bitcoin/crypto exposure as part of the overall valuation. Ives has a Neutral rating and a $950 price target on the shares, with $1,250 bull case.
