In Tuesday's Analysts' Actions, TheStreet highlights a positive note on Salesforce (CRM) as well as a couple of downgrades on Shake Shack (SHAK) and Tesla Motors (TSLA) by Wall Street firms. Analysts at Deutsche Bank lowered their rating on the electric car maker to HOLD from BUY, but still liked its battery systems technology. The firm increased its price target on shares of Tesla to $280 from $245. Analysts at Morgan downgraded burger joint Shake Shack to UNDERWEIGHT from EQUAL WEIGHT, while maintaining its $38 price target. Analysts believe the stock is 'expensive.’ And, Brean Capital analysts upgraded Salesforce to BUY from HOLD with an $85 price target. The firm sees the company’s growing opportunity to upsell customers on its cloud-based services. TheStreet's Kurumi Fukushima reports in New York.
