The weekly chart shows a red line through the price bars, marking the key weekly moving average (a five-week modified moving average). The green line is the 200-week simple moving average, the "reversion to the mean." The study in red along the bottom of the chart is weekly momentum (a 12x3x3 weekly slow stochastic), which scales between 00.00 and 100.00, where readings above 80.00 indicate overbought and readings below 20.00 indicate oversold. A negative weekly chart shows the stock below its key weekly moving average, with weekly momentum declining below 80.00 in a trend toward 20.00.

Remember that stochastic readings can help investors judge when to reduce long positions. The 12x3x3 weekly slow stochastic is based upon the last 12 weeks of data: each week's high, low and last prices. This measure of momentum rises as a new weekly high occurs, with the last price closer to the high. When this pattern changes and the weekly last price is closer to the low, the stochastic reading will begin to decline, providing an early warning to reduce holdings.

The weekly chart for J.B. Hunt will shift to positive if the stock ends the week above its key weekly moving average of $80.85. The stock is above its 200-week simple moving average of $77.23, last crossed during the week of Feb. 12, when this average was $72.46. The weekly momentum reading is projected to end the week at 40.30, up from 36.92 on Oct. 7.

Investors looking to buy J.B. Hunt should consider doing so on weakness to $78.52, which is a key level on technical charts until the end of this week only.

Investors looking to reduce holdings should consider selling strength to $86.32 and $89.94, which are key levels on technical charts until the end of 2016 and until the end of October, respectively.
