NEW YORK ( TheStreet) -- On Thursday, we get earnings reports from a sell-rated trucker, a strong sell-rated semiconductor company and a hold-rated food and drug retailer. More important in my judgment are earnings from two of the four "too big to fail" money-center regional banks.The computer and technology sector is 23.1% overvalued, but has an overweight rating with 43.8% of the 1,163 stocks in this sector rated buy or strong buy. The finance sector is 17.3% overvalued with an equal-weight rating. The retail-wholesale sector is 24.5% overvalued, but has an overweight rating with 79.4% of the 354 stocks in the sector rated buy or strong buy. The transportation sector is 24.4% overvalued with an "avoid-source-of-funds" rating with 74.3% of the 179 stocks in the sector rated sell or strong sell. One of the five stocks previewed today is undervalued by 7.8%, with the other four overvalued by 14% to 92.8%. Three stocks have hold ratings, one has a sell rating and one has a strong sell rating. All have gains over the last 12 months with one gaining 92.5% and another soaring by 216.2%. All are trading above their 200-day simple moving averages, which reflects the risk of reversion to the mean.
