Goldman Sachs Group Inc. (NYSE:GS) reported a 29% gain in first-quarter profit, handily beating analysts' forecasts and investors probably could care less. Wall Street is waiting on pins and needles to find out whether the largest securities firm escaped the black hole engulfing suprime lenders.

As Bloomberg News notes, Goldman Sachs is a lender to New Century Financial Corp. (NYSE:NEW), the suprime lender that can't pay its creditors. Shares of the Goldman have slumped 8.3% since February 20 amid concerns that the real estate market will fall because of higher interest rates resulting in a slowdown of the economy, Bloomberg said.

Not suprisingly, New Century shares were halted yesterday after plunging nearly 90% last week. Another subprime lender Accredited Home Lenders Co. (NASDAQ:LEND) plumetted 27% yesterday and plunged another 43% in pre-market trading.

Suprime lending is bound to come up over the next two weeks when Bear Stearns Cos. (NYSE:BSC), Lehman Brothers Holdings Inc. (NYSE:LEH) and Morgan Stanley (NYSE:MS) report earnings.
