Technical Methodology

The weekly chart shows a red line through the price bars, which is the key weekly moving average (a 5-week modified moving average). The green line is the 200-week simple moving average considered the "reversion to the mean".

The study in red along the bottom of the charts is weekly momentum (a 12x3x3 weekly slow stochastic), which scales between 00.00 and 100.00, where readings above 80.00 indicates overbought and readings below 20.00 indicates oversold.

A negative weekly chart shows the stock below its key weekly moving average with weekly momentum declining below 80.00 in a trend towards 20.00. A positive weekly chart shows the stock above its key weekly moving average with weekly momentum rising above 20.00 in a trend towards 80.00.
