NEW YORK ( TheStreet) -- Today's buy-and-trade earnings previews focus on 11 companies in nine sectors including Dow component Disney ( DIS) which reports in afterhours trading on Thursday and Priceline ( PCLN) which also reports afterhours Thursday. It will be interesting to see whether or not Priceline can stay above a grand a share.The eight sectors include two stocks from the consumer discretionary sector and two from the industrial products sector, and one each in these sectors; auto-tires-trucks, computer and technology, construction, consumer staples, medial, oils-energy and retail-wholesale. With the stock market near all-time -- multi-year highs, and with the yield on the 30-year Treasury bond rising to 3.75%, the ValuEngine valuation warning intensified to a year to date high with 83.3% of all stocks overvalued. The percent of all stocks overvalued by 20% or more is also at a 2013 high at 53.3%.
