NEW YORK (TheStreet) -- TheStreet Ratings released rating changes on 11 U.S. common stocks for June 21, 2010. Six stocks have been downgraded and five stocks have been upgraded by our stock model.

The largest company among the five upgrades is Limited Brands ( LTD) with a market capitalization of $7.85 billion. This specialty retailer of Victoria's Secret lingerie is busting free of the U.S. market with a planed store opening in London by 2012 and four Canadian stores this year.

Heading the other way, the model downgraded the $21.1 billion Yahoo ( YHOO) to 'Hold' from 'Buy'. The model found the stock performance to be disappointing as the shares test their 52-week low of $13.97 and considers the company's operating cash flow to be weak. Net operating cash flow has decreased to $143.6 million or 45.3% when compared to the same quarter last year.
