A handful of stocks broke out to new highs, but they were in mostly light volume due to Friday’s half-day session. Constellation Brands (STZ) gapped up as it added 1.64, or 2%, to 96.40 in less than half its usual trade. The stock is now 2% above a 94.87 buy point of a flat base that it initially cleared Nov. 12 but hadn’t yet closed above the entry.
