GoPro, Inc. (GPRO​) shares fell more than 10% in early trading on Thursday despite the company reporting better-than-expected third quarter financial results. Revenue rose 37.1% to $329.81 million – beating consensus estimates by $16.71 million – and earnings per share of 15 cents beat consensus estimates by 13 cents per share. The problem was that full-year revenue guidance came in sharply lower than analysts were expecting at $1.305 billion to $1.325 billion.

Prior to the third quarter financial results, some analysts had been bullish on the company's prospects. Longbow upgraded the stock to Buy with a $13.00 price target on Oct. 18, saying that management had stabilized the business and improved execution. Interestingly, the analyst firm moved $30 million of its forecast fourth quarter sales to the first quarter due to planned inventory reductions, which could be the cause of the lower guidance.

Technical chart showing the performance of GoPro, Inc. (GPRO) stock

From a technical standpoint, the stock moved sharply lower and could break down from a head and shoulders pattern. The relative strength index (RSI) moved into slightly oversold levels at 41.18, while the moving average convergence divergence (MACD) could see a bearish crossover in the near term after experiencing a brief rally late last month. Traders should maintain a bearish bias on the stock given the full-year guidance and chart patterns.

Traders should watch for a breakdown from the shoulder line, S1 support and the 200-day moving average at around $9.06 to S2 support levels at $7.91. If the stock manages to hold these support levels, traders should watch for some consolidation around S1 support before a move in either direction. The crossover of the 50-day moving average above the 200-day moving average suggests a moderate bullish bias over the long-term, but the short-term bias is bearish.
