A few dents have appeared in the armor of some Sector Leaders this week. Autohome (ATHM) broke out of a flat base Monday with a 53.66 buy point, then reversed to finish slightly lower. Then, Tuesday, the stock tumbled 3.04 to close at 50.25, a 6% drop. UBS downgraded the stock from buy to neutral. Chinese stocks were generally weaker. Autohome, though volatile, has put up sterling numbers.
