Goldman said digital sales will drive the next leg of the stocks rally.

Starbucks – Shares of Starbucks dropped about 1% after J.P. Morgan said the stock’s “upside from here is limited” and cut its rating on the company to neutral from overweight. Starbucks stock has climbed more than 90% in the past 12 months.

Boeing – One of the laggards of the Dow Jones industrial average, Boeing’s stock fell almost 1% after analysts at credit agencies Standard & Poor’s, Moody’s and Fitch released ratings that gave a cautious outlook on the aerospace giant’s debt due to the prolonged 737 Max crisis.

UPS – Shares of UPS fell 1.6% following a downgrade from Stifel. The firm lowered its rating to hold and maintained its $118 per share price target, saying it does not feel comfortable pushing the valuation multiple up enough to continue to recommend a buy.
