An advance that sent stocks to record highs faded into the close as two major market events collided, spurring one of the year’s busiest trading days.

More than 10 billion shares changed hands on U.S. exchanges Friday, about 65 percent above the three-month average. The S&P 500 ended Friday little changed at 4 p.m. in New York, after initial gains failed to hold amid the quarterly event known as “quadruple witching” -- when futures and options on indexes and individual stocks expire.
