Traders work on the floor of the New York Stock Exchange.

Stocks could continue to shake off the recent round of weak data Wednesday, as Apple unveils its new iPhone 7 and two Fed officials are on the hot seat before Congress.

There are two economic reports the market is watching Wednesday. One is the 10 a.m. release of JOLTS, job opening and turnover data, and the other is the release of the Fed Beige Book on the economy at 2 p.m. EDT.
