Will the fifth 20-plus percent rally of this historic bear market be the charm? You got me. All I know is that one more new gut-wrenching low and the stock market runs the risk of becoming as popular as corncob art, and even less expensive. The Wall finally loses one worry, but simmering global political risks and ballooning deficit-funding needs in the U.S. and the U.K. loom large. Is this the bottom for the market? Yup, nope, maybe — whatever happens, it’s time to start buying your favorites for the long, long term.
