Twitter is one of the most fascinating battleground stocks in the market.
The shares are down 14 percent this year through Tuesday's close. However, the stock is up 47 percent from an all-time low hit in August after finally naming co-founder Jack Dorsey as chief executive. The shares were also helped by votes of confidence from Saudi Prince Alwaleed and a former Microsoft CEO Steve Ballmer.
Despite the comeback, Wall Street analysts are increasingly negative on the social media darling punctuated by Morgan Stanley's Brian Nowak's downgrade Wednesday to "under weight" from "equal weight."
Nowak believes Twitter will miss Wall Street numbers materially in the future. His forecast for 2017 sales is 18 percent lower than consensus, and his earnings forecast is 25 percent lower than the rest of Wall Street.
