This year through mid-September, the 76 companies in the Standard & Poor's 500-stock index that do expense options saw their share prices rise 15.9%. Those that didn't? Up 25.3%. The most honest defense for companies unwilling to deduct options expenses, Morgan Stanley concludes, "is that if analysts start recognizing options as a cost, earnings estimates will decline and [stock prices] will fall." Accounting authorities recently postponed rules mandating expensing of options -- a depressing, if perhaps pragmatic, signal to stay bullish on stocks. Ez-D DVDs have the same sound and picture quality as conventional dvds but without extras such as commentary. Oh, and another thing: They self-destruct in 48 hours. The disposable disks just became available in Austin, Tex., Charleston, S.C., Kansas City, Mo., and Bloomington/Peoria, Ill. Buy one or about $5 (the price of a rental), play it as much as you want for 48 hours, then send the disk to a recycling facility or throw it away. If you don't open the package, it has a shelf life of one year.
