Several leading stocks hit new highs Friday as the market rebounded for a second day. The new-highs list has been short and composed mostly of low-quality stocks since the market correction began Oct. 1. But the list’s composition has improved a tad in the past couple days. Regeneron Pharmaceuticals (REGN) soared 28.93 — 8% — to 369.64 in heavy volume, breaking out above a 369.41 buy point of a flat base-on-base.
