Wall Street Advances in Short Christmas Eve Session on Megacap Gains

WALL STREET - NEW YORK. Wall Street's main indexes advanced on Tuesday, as gains in a handful of megacap and growth stocks bolstered benchmarks in a truncated trading session before Christmas.

With megacap stocks having outsized influence on markets, their performance is often a key driver of indexes. When coupled with reduced trading volumes and few other catalysts, as many investors take time off for the holidays, this is even more pronounced.
