"Wearable fitness device maker Fitbit Inc's (FIT.N) revenue forecast for the key-holiday shopping quarter fell well below of analysts' estimates, hurt by soft demand and production issues related to its new Flex 2 wristband.
Shares of the company, which also reported lower-than-expected quarterly revenue, plummeted more than 30 percent in extended trading on Wednesday and were set to hit record-low levels on Thursday."
