To get a full picture from a technical perspective, Cramer spoke with Larry Williams to figure out what could be in store for Costco's stock. Williams has traded stocks, commodities and futures for over 50 years, written 11 books, created various technical indicators used in the industry and teaches investors about the market on his website IReallyTrade.com.
When Williams looked at the charts for Costco, he couldn't help but notice the inter-market relationship with the dollar index. When the dollar is strong, Costco tends to perform well. The dollar index measures the value of the U.S. dollar versus a basket of the next six largest currencies.
"If you project this relationship forward given the recent strength in the dollar, Williams thinks that Costco could be on the verge of a significant rally," the "Mad Money" host said.
