Gopro (NASDAQ: $GPRO) is down 28% since hitting a peak in the first week of October. A lock up withdrawal of 5.8M to start a charity was a signal that more "downside" was to come. On December 23, just about every share remaining in the lock up (borrowed money) will be made public, thus flooding the market with supply; driving the price down even further. Lean into the Puts two months out. Once Earnings is over, there might be a valuation adjustment to set a fair market value on the market. I'll close when I see a peak gain at 100% in profits. But til then I'm Bearish with a Full House Of Puts, so far in my favor. Read the article in the Business Insider for an explanation on borrowing for shares.
