NEW YORK (Reuters) - Stock futures pointed to a modestly higher open on Friday, putting the S&P on track to extend its record high with a sixth straight day of gains, and a fourth weekly gain over the past five.
Investors may see a spike of volume and volatility at the open and towards the closing bell as Friday marks a "quadruple witching" day - the expiration of stock options, index options, index futures and single-stock futures - as traders close hedging positions or roll them over at the last minute.
