Since then, the stock has had a tremendous run, and Lang pointed out that whenever this stock pulls back, that is an amazing buying opportunity. Lang thinks the uptrend of the stock will continue, especially with Peltz putting the heat on management to produce additional value.  Next up is Dow Chemical, which recently spun off its commodity business so it could focus on higher-margin proprietary business. Lang pointed out that the stock has been consistently making higher highs and lower lows lately, which is exactly what a technician wants to see in a healthy chart.  The consistent call buying on Dow shows that Wall Street folks think that this stock is headed higher. Additionally, the Dow chart shows that it just finished a cup-and-handle pattern, which set the stock roaring. Lang added that Dow is his favorite stock to buy in the group right now.  LyondellBasell is another high-quality chemical company that has had some wild moves. Since 2011 this stock is up nearly tenfold. It pulled back 50 percent in 2012, which turned out to be an excellent time to buy it. In the past few months it has pulled back again, leading Lang to believe that this is a great time to buy it.  Last, there is Cramer-fave PPG.  ---------------------------------------------------------- Read more from Mad Money with Jim Cramer Cramer Remix: How to benefit off the Fed Cramer: Einhorn was dead wrong on EOG Cramer: Thanks for nothing, Janet Yellen! ----------------------------------------------------------  "I adore PPG, both the company and the stock, but according to Lang this is actually the weakest of the chemical charts," Cramer added.  PPG has been giving off a W-pattern since March, and the charts indicate it is about to have a bullish crossover. If that happens, then Lang thinks the stock will break out of its current patterns and go back to $237.  In the end, the market is confusing and at least investors can have some sense of comfort by looking at the charts to see what looks good. Lang sees that the chemical stocks are in a great position right now, especially Dow.
Jim Cramer sees the market is unpredictable, so he went off the charts to reveal one group that has all the stars aligned for success.
