Yes, nimrod CFO during earnings call made a comment that teen usage was decreasing on FB site, although never followed through with statement by saying teens were moving to Instagram, a company FB owns. The stock was up precisely 16 percent when he made that statement, I know because I was watching the level II screen after hours. That one comment cost me close to 14k. Hopefully he keeps his yap shut this time and let the earnings numbers do the talking!
