The retail sales data in China came in at 10% growth in May, slightly below economists' expectations for 10.1% growth. Next up? The U.S. retail sales results for May.

On Tuesday, economists will be looking for growth of 0.3%. TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, will be keeping an eye on the results.

Retailers have continued to struggle mightily, with the exception being stores like Big Lots (BIG - Get Report) , TJX (TJX - Get Report) , Walmart (WMT - Get Report) , Dollar Tree (DLTR - Get Report) and Dollar General (DG - Get Report) , Cramer said.

But you know which retailer continues to gain traction? That's right, Amazon (AMZN - Get Report) .

"I just want the Amazon sales," Cramer said. "That's what tells me how things are going."

The stock prices tell a similar story. The SPDR S&P Retail ETF (XRT - Get Report) is down 4% on the year and 16% over the past 12 months, while shares of Amazon are up 6% in 2016 and up a whopping 67% over the past year.

At the time of publication, Cramer's Action Alerts PLUS had no position in companies mentioned.
