Leading stocks took their licks in the past week, with only a small clique of IBD 50 stocks posting weekly gains. Among those, China-based TAL Education (XRS) hauled in an 11% gain to end the week at a new high. That left the chain of tutoring centers for kindergarten through 12th grade well extended after its first test of 10-week support since a breakout from an undefined, late-stage base in June.
