NEW YORK ( TheStreet) -- Today I preview ten companies in the retail wholesale sector who report quarterly results Thursday and premarket Friday. All 10 have buy ratings according to ValuEngine. The retail wholesale sector is 24.9% overvalued, but with more than 70% of all stocks in the sector rated buy, it's a sector that continues to have an overweight rating.Most of the retailers previewed today are in the malls around the country, and cater to folks of all ages for their casual apparel needs; from infants to preteens, teenagers and young adults. A few of these stores compete against each other. Once consumers buy the clothing and footwear of their choice, they can turn to a closeout retailer of merchandise and toys, and check out video and entertainment software. With any money left in their pockets they can also visit a discount variety store before ending their shopping spree. This morning the ValuEngine valuation warning continues with 75.8% of all stocks overvalued 43.2% by 20% or more. 15 of 16 sectors are overvalued, 12 by double-digit percentages, seven by more than 20%.
