NEW YORK ( TheStreet) -- The yield on the U.S. Treasury bond approached 4% this week, which caused stocks to become more overvalued of less undervalued.Friday, the ValuEngine valuation warning continues with 75.5% of all stocks overvalued 40% by 20% or more; 15 of 16 sectors are overvalued 13 by double-digit percentages. Six sectors are overvalued by more than 20% with the autos-tires-trucks the most overvalued by 26.4%. The auto-tires-trucks sector is rated underweight with only one buy-rated stock and with 36.6% of all stocks rated sell. The 14 stocks for this sector that I profile today have gained between 33.3% and 508.2% over the last 12 months, with four setting new multi-year or all-time highs this week. Eight of these stocks are rated hold and six are rated sell; 13 are overvalued by more than 20%, by 22.3% to 51.4%. All are above their 200-day simple moving average, which reflects the risk of a reversion to the mean.
