SAN FRANCISCO -- Stop me (oh ho ho) stop me, stop me if you think that you've heard this one before:

Alan Greenspan

spoke about the likelihood of higher interest rates today, sending blue-chip stocks reeling.

But in a new twist on the old song, tech favorites couldn't resist the siren selling in "old economy" stocks, and the

Nasdaq Composite Index

retreated from its record-setting pace. The

Russell 2000

set another record but even that small-cap proxy cooled off in the final hour, as the majority of stocks reflected the mood of most songs by

The Smiths

. (Depressed, that is.)

"Until market forces, assisted by a vigilant

Federal Reserve

, effect the necessary alignment of the growth of aggregate demand with the growth of potential aggregate supply, the full benefits of innovative productivity acceleration are at risk of being undermined by financial and economic instability," Greenspan said in a

speech at a conference at

Boston College


Those remarks (and others) poured cold reality on anyone who thought Friday's

employment report would prompt the Fed to rein in its aggressive monetary stance. A rethinking of that notion -- which helped spur stocks higher across the board

Friday -- snapped the five-session winning streak of the

Dow Jones Industrial Average

, which fell 196.70, or 1.9%, to 10,170.50 after trading as low as 10,121.48.

The price of the 10-year Treasury note fell 7/32 to 100 18/32, its yield rising to 6.42%.

But Brian Belski, chief investment strategist at

George K. Baum

in Kansas City, Mo., argued Greenspan didn't depart from his recent commentary and thus wasn't truly responsible for the action -- a view shared by many.

"You're seeing a normal pullback from

the Dow being overextended as of Friday," Belski said of today's setback. "It's all normal-type action."

Further supporting the notion that today's decline was more of a technical move than fundamental story, financial stocks were relatively unscathed today, the strategist noted. "It's more a case of some of these Dow stocks bounced up too much from oversold."

Market players debate the significance of round numbers, but "the Comp rolled right off 5000 and came back with the rest of the broader market," noted one equity trader. "Everyone was yelling '5000, 5000' and it never stood a chance. This group will continue to do well, but today you saw some of the volatility increased."

No Unifying Theme

Despite the hubbub about Greenspan, there was no overarching factor moving stocks today, traders said.

Jay Meagrow, vice president of trading

Goldman Sachs

while utility stocks got "pummeled" after
