NEW YORK (TheStreet) -- Shares of Fitbit  (FIT) were plummeting 30.60% to $8.89 in after-hours trading on Wednesday after reporting 2016 third-quarter revenue below analysts' expectations and guiding for fourth-quarter and full-year earnings and revenue well below consensus estimates. 

After the market close, the San Francisco-based maker of wearables said third-quarter revenue grew 23% year-over-year to $503.8 million, but missed analysts' estimates of $506.9 million.
