San Francisco Fed chief Mary Daly and her Chicago counterpart Austan Goolsbee stepped in. They pointed out two things: One, the data doesn't scream "recession." This is the USA, after all, the land of Chuck Norris. America doesn't do "backwards." Two, the conditions are ripe for the central bank to cut rates and avoid a financial mess. Plus, the ISM services index showed that the U.S. economy still has some pep in its step, which doesn't quite jive with the panic-induced nosedive we saw.

In corporate news, Construction and materials stocks led the rebound, with Keller Group surging 12%. Large banks were also among top gainers, and energy shares rose as oil prices rebounded.

InterContinental Hotels Group enjoyed a 2.5% boost after reporting a 3.2% rise in Q2 revenue per available room. On the downside, Travis Perkins dropped 2% after slashing its annual earnings forecast. As for the economic indicators to watch on Tuesday, keep an eye on German factory orders, UK construction PMI, and EU retail sales.
