In Tuesday's edition of Mad Money, Jim Cramer went "Off the Charts" to check in with colleague Bob Lang over the charts of "FANG," his acronym for Facebook (FB) - Get Report , Amazon.com (AMZN) - Get Report , Netflix (NFLX) - Get Report and Alphabet (GOOGL) - Get Report , formerly Google.

Cramer noted that since introducing FANG in February 2013, the four high-growth stocks are up 250%, 81%, 246% and 83%, respectively. But recently FANG has also been in the grips of the bear, prompting a re-evaluation from Lang.

Using long-term monthly charts, Lang noted that Facebook has remained above its 20 and 30-day moving averages for almost nine years. The Chaikin money flow has also confirmed the uptrend. Google and Netflix displayed similar patterns, with pullbacks to the 20-month average but all part of a healthy uptrend.

Taking a shorter-term view with a daily chart, Lang saw Facebook's floor of support at its 200-day moving average, and the possibility of returning to its old highs if the 50-day average can be breached.

As for Alphabet, Lang called out the recent morning star pattern, which could take those shares back to their 50-day moving average.

Lang saw the daily chart of Amazon being problematic, however, as that stock has dipped below the 200-day moving average on high volume, making Amazon a tough chart to gauge. He was more bullish on Netflix, however, as that stock has a floor of support around $80 a share.

Cramer agreed with Lang's analysis that the long-term bullish thesis of FANG continues, but shorter term there may be more pain ahead before things start to get better.

At the time of publication, Cramer's Action Alerts PLUS had a position in FB and GOOGL.
