NEW YORK, March 20 (Reuters) - The U.S. dollar rebounded broadly on Friday from a slide sparked by the Federal Reserve's move to buy up to $300 billion of government debt and U.S. stocks slipped on the tepid debut of a Fed measure to revive lending.
While U.S. stocks and Treasuries slipped, in Europe stocks and government debt prices rose as investors still mulled the potential impact of the Fed's plan announced on Wednesday to pump an additional $1 trillion into the flagging U.S. economy.
Gold edged down as the dollar rebounded against the euro, prompting profit taking, and a two-day rally in commodity markets cooled as investors worried about demand.
Oil hovered above a four-month high at $52 a barrel, recouping earlier losses as the market sought a new base after news of a collision in the key Strait of Hormuz shipping lane near Iran.

"The market is see-sawing today. What we have seen here is investors downsizing their positions, taking half of their profits out but still leaving some positions in," said Joshua Raymond, market strategist at City Index.
"Investors are still fairly confident that the market could go higher, but yet again they do not want to take the risk in case the market turns. ... There are still concerns about bank liquidity and return on investment," added Raymond.

But U.S. Treasury debt prices barely budged as investors paused after the Fed plan set benchmark yields on track for their biggest weekly drop this year.
