Jim Cramer's FANG stocks -- Facebook (FB) , Amazon (AMZN) , Netflix (NFLX)   and Google's parent Alphabet (GOOGL) -- are a group of tech stocks he has been watching. Let's check in on their technical charts.

Facebook, Amazon and Alphabet are showing overbought conditions with positive weekly charts, while Netflix has been the laggard and is not yet overbought.

Jim Cramer and Research Director Jack Mohr of Action Alerts PLUS wrote in their weekly roundup to investors that Alphabet "remains on the right track." They said they were reassured by reports of continued growth for YouTube, which Alphabet owns. They added that Alphabet's cloud services make it "a serious competitor to top-tier services like Amazon Web Services," a dominating cloud company.

Facebook and Alphabet are holdings in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio. Want to be alerted before Cramer buys or sells FB or GOOGL? Learn more now.

Here's today's FANG scorecard.

 

The weekly charts show 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.
