Updated with additional information on previous news leaks.
NEW YORK (TheStreet) -- When shares of Twitter (TWTR) - Get Report dropped more than 5% immediately after Selerity tweeted the company's earnings ahead of its scheduled reporting time, the online investor service posted its own tweet asserting that there was "no leak" and "no hack" as the data was already available on Twitter's Web site.
Twitter was set to disclose its earnings after the market's close on Tuesday, but the Selerity tweet caused shares to tumble and volume to skyrocket. The stock lost 18% on the day and continued to fall in after-market trading.
Selerity posted that first-quarter earnings per share beat estimates at "$0.07 vs. $0.04 expected," and that average monthly users, at 241.6 million, missed estimates by more than 1 million.
Selerity's post is eerily familiar to the company's tweet last year that it had not "leaked" private payroll figures from Automatic Data Processing (ADP) - Get Report before they were set to go public. The incident followed another widely reported Selerity public disclosure of Microsoft's (MSFT) - Get Report quarterly earnings in January 2011.
