Trader sentiment on Alibaba is surging

Chance Chan | Reuters

Bullish mentions of Alibaba's stock on Twitter dramatically increased in the past week after the company reported better-than-expected fiscal first quarter earnings.

Social Market Analytics, which scans posts on social networks to form predictive trading signals, found that Alibaba had the biggest jump in bullish mentions among major U.S. stocks in the last week.

Shares of the Chinese e-commerce giant, which announced its earnings on Thursday, were up 19 percent year to date as of Tuesday's close. If the data are any indication, traders are betting the run will continue.

"We're just killing it on mobile," Alibaba vice chairman Joe Tsai told CNBC's "Squawk on the Street" last Thursday. "We have just reported that our monetization of mobile users has exceeded the monetization of the users on PC."

Below are the top five stocks seeing the biggest one-week jump in bullish sentiment on Twitter, according to SMA.
