GoPro appears to be ending the decline that has battered it since the August swing high, near $65. With the stock now near $30, down more than 53% in just a couple of months, it is at its most oversold since March. With prices at lower lows now vs. then, and stochastics at higher lows, a bullish divergence buy signal has been triggered. Another buy signal will be triggered as the price moves back above the lower two-standard-deviation band (now $31.63 on daily bar charts), which contains 95% of normality. The weekly bar chart above shows both of these indicators, along with a mature impulsive decline (labeled 1 through 5 off the August highs). The bold red vertical lines show theFibonacci relationship between waves A-circled and C-circled. The latter is Fibonacci 62% of the size of the former. This common symmetry is highly supportive of the decision support engine's forecast that now is the time for buying actions only. The blue arrows chart the path of the forecast for the next several months to quarters.
