Wall Street is bailing on Twitter's stock.

Seven analysts downgraded the shares amid a seven-week period that saw the social networking company announce abysmal first-quarter results and replace its embattled CEO Dick Costolo.

The stock got a small pop Friday after Costolo stepped down, but it's down almost six percent to a 52-week low through trading midday Tuesday.
