New York | Nomura Instinet analyst Romit Shah downgraded Tesla on Tuesday from buy to neutral in a note titled "No Longer Investable". The note to clients starts by pointing out that previously he's been one of the biggest bulls on the Street since initiating coverage last October.

Shah slashed his price target on the company to $US300 ($421.60) from $US400 citing the "erratic behaviour of CEO Elon Musk". Among Shah's concerns: The increasing number of Musk tweets per day, his cave diver accusations, his outbursts on an earnings call, his taunts of short sellers and his appearance on Joe Rogan's podcast.
