Stocks rose Monday, led by banks after Greece's parliament approved strict financial reforms needed to obtain an international bailout package.
The deal helps Greece avoid a potentially chaotic default, though the government remains under pressure to convince a skeptical euro zone that it will abide by the terms of the package.
