Tesla (NASDAQ: TSLA) shares are under pressure again amid concerns about the 'go-private' deal and potential enforcement action following Elon Musk's tweet. JPMorgan slashed its price target on the stock 37% to $195 today, saying funding does not appear secure. Meanwhile, Tesla bulls are finding some solace in the fact that Musk unfollowed girlfriend Grimes on Instagram and Twitter - suggesting they may no longer be an item. This, bulls say, could allow Musk to get back on track mentally.
