NEW YORK (TheStreet) --Shares of Amazon.com (AMZN) are lower north of 5% over the past week after the e-commerce giant reported weaker-than-expected earnings last Thursday. In response, Ritholtz Wealth Management CEO Josh Brown explained the Amazon trade during CNBC's "Fast Money Halftime Report" today.

"I think the important level here for traders, people trying to get an edge on where they think the next stop is, is $800 that's the 50-day," Brown said. "The 50-day moving average on the way up was a very reliable area for support; that's where the buyers came in on every hiccup."

However, that previous level is starting to act as resistance, he noted.

"We saw the stock bounce back after the earnings slide, got right up to that level, and then was turned away," Brown explained.

He believes that is the level where the sellers have now "taken control."

"If you can get a close appreciably above $800 on good volume, maybe even on a weekly basis, maybe that's where you see the buyers become embolden," Brown added.

Until that level, however, he thinks this is a "tough" stock to be long in terms of a trader's perspective.

Separately, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.

The team rates Amazon.com as a Buy with a ratings score of B-. COM INC (AMZN) a BUY. The company's strengths can be seen in multiple areas, such as its impressive record of earnings per share growth, compelling growth in net income, robust revenue growth, expanding profit margins and good cash flow from operations. Although the company may harbor some minor weaknesses, the team feels they are unlikely to have a significant impact on results.
