JPMorgan analyst Doug Anmuth upgraded Twitter (TWTR) to Overweight and raised his price target for the shares to $27 from $20.

The stock closed Friday down 35c to $22.23. The analyst calls Twitter one of his top mid-cap ideas for 2018. Both the company's investment story and financial results will strengthen in 2018 as Twitter builds on its "differentiated value proposition" for users and returns to revenue growth, Anmuth tells investors in a research note.

He believes the company's products are improving led by video and live streaming content while investor sentiment remains mixed.
