Shares of Twitter (TWTR) - Get Report were higher in late afternoon trading on Tuesday, despite Sony Music's (SNE) - Get Report account being hacked and tweeting out a false claim that pop singer Britney Spears had died. The stock is down over 28% YTD. 

"We want to be positive on Twitter because we like the service, but it's just getting so hard to continue to defend this. I mean day after day," Monness Crespi Hardt analyst James Cakmak said on CNBC's "Power Lunch" on Tuesday afternoon. 

The hacking aside, Twitter said last week that it over-reported video ad views from its Android app, Cakmak noted. "When you talk with these advertisers and these advertising agencies, the confidence there is certainly eroding."

In addition, Twitter's management has a high turnover rate, its CEO Jack Dorsey is running both Twitter and Square (SQ) - Get Report at the same time, and there's no plan in place for verifying accounts, he noted. 

"Look we can keep going on and on about Twitter, but the user growth needs to come back," he said. "And over the near-term, I think fourth quarter for the December quarter could be the first ever revenue decline for Twitter. So stay tuned for that."
