4:30 pm : Stocks pushed higher in broad-based fashion as participants took their cues this session from the dollar, which was weakened despite conflicting reports about whether Germany will lead a bailout for Greece.

Concern for the fiscal health of Greece had sent many global participants to seek safety in the U.S. dollar during recent sessions, such that the dollar hit a multimonth high against competing currencies last week. However, speculation today that Greece could receive help from Germany gave the euro strength, which dropped the Dollar Index for a near 0.7% loss this session.

There hasn't been any official statement regarding whether Germany will support Greece or if any plan would offer support to other troubled European countries, like Portugal and Spain. Notably, any such plan would likely weigh on Germany's fiscal health, but the market still treated the notion of any such effort as a positive.

Given the greenback's weakness this session, natural resource plays made the strongest moves. As such, materials stocks advanced a collective 2.5%. An upgrade of Monsanto (MON 75.72, +1.51) from analysts at Bank of America's Merrill Lynch helped shares of the seed company show leadership.

Morgan Stanley's upgrade of Caterpillar (CAT 53.53, +2.75) helped shares of the industrial outfit log their best session in nearly one month. The stock was a primary leader in the Dow, which had been up more than 200 points at its session high.

Fellow Dow component Coca-Cola (KO 54.01, +1.36) also provided leadership to blue-chips, even though it missed Wall Street's consensus earnings estimate for the latest quarter.
