After a string of horrible days in the markets, you may be left wondering why it's even worth trying to pick stocks any more. But on Mad Money Tuesday night, Jim Cramer argues that even with the crazy days, the stock market remains an engine for wealth creation.

To get back on track he welcomed to his "Off the Charts" segment Bob Lang, founder of ExplosiveOptions.net, and contributor to TheStreet.com's Trifecta Stocks newsletter.

The past week has been rough for FANG, Lang's acronym for Facebook (FB) , Amazon (AMZN) , Netflix (NFLX) and Alphabet (GOOGL) .

Google parent Alphabet's results disappointed. Facebook reported and in comments confirmed the bearish narrative about the stock. And Amazon and Netflix were slammed Monday with the rest of the market.

Of course, if you'd bought the FANG names five years ago, you'd have average gains of 534%. Normally, you'd only expect to see such mammoth gains from tiny, small-cap stocks, but these are some of the largest companies on earth. To put their moves in perspective, the Nasdaq's up 102% over the same period, while the S&P 500's up 70%. That's not bad, but FANG leaves the averages in the dust.

As Lang argues, the group has incredible staying power thanks to the leadership of Mark Zuckerberg at Facebook, Jeff Bezos at Amazon, Reed Hastings at Netflix and Eric Schmidt and Larry Page at Alphabet.

The question is whether FANG can continue to perform this way.

They started by looking at daily chart of Facebook. Lang noted that Facebook has been making a nice consistent pattern of higher highs and higher lows for ages, and that's very bullish. But in Monday's breakdown, the stock pulled back to $180. Lang points out that Facebook has a nice floor of support right here at just under $180.

Since last fall, the stock has bounced from this level three times. Will it bounce again? Lang thinks so. He likes that the Chaiken Money Flow, which measures the level of buying and selling pressure in a stock, has remained positive, indicating that the big institutions still have an appetite for Facebook. Put it all together and he wouldn't be surprised if Facebook can make a move to $200 in the not too distant future.

Lang and Cramer looked at Amazon next. Amazon pulled back hard Monday. But as Cramer and Lang pointed out, a little more than three months ago, Amazon was a $970 stock. Now, even after Monday's slide, it's at $1,400. Lang likes that the Chaiken Money Flow has stayed strong here, and he also likes that the stock's recent rally happened on strong volume. Lang sees it making a run toward $1,500 before too long.

 

Two weeks ago, Netflix rocketed higher on a very strong quarter. Like the other FANG names, it pulled back in recent sessions. Lang likes that these declines happened on falling volume. Remember, volume is like a polygraph for technicians and weak volume suggests that a move is lying. Meanwhile, Netflix has a nice floor of support at its 20-day moving average, currently at $242, and the Chaiken Money Flow is still very high, meaning the big institutions continue to lap this stock up. Lang believes Netflix can go up to $300 in fairly short order.

 

Alphabet fell off a cliff after it reported Thursday and got slammed again Monday. This is the one FANG component that Lang's not feeling quite so sanguine about. The Moving Average Convergence Divergence, or MACD indicator, a tool that helps technicians detect changes in a stock's trajectory before they happen, just made a bearish crossover, where the black line goes under the red one. These MACD crossovers tend to be surprisingly reliable signals. On the other hand, the money flow is still very strong with this one.

Though Alphabet remains above its 200-day moving average, it's now back where it started the year. Lang could see Alphabet getting hammered down to $1000. At that level, though he thinks it would be a buying opportunity, and if the stock can settle down a bit, he wouldn't be surprised if it can head back towards $1,200. But it's probably going to $1000 first.
