Goldman Sachs Downgrades Tesla, Stock Continues to Drop.

Goldman Sachs downgraded its recommendation on Tesla's shares from buy to neutral, citing the substantial surge in the shares as well as price declines for new cars. This marks at least the fourth downgrade in the past week, with analysts on average now expecting the stock to drop 18% in the next 12 months. Despite Tesla's more than doubling in value this year, Wall Street warns that the stock has become "overbought" and investors are too optimistic about its artificial intelligence credentials.
