Updated from 4:17 p.m. EST

The recent sluggishness for U.S. stocks continued Monday, and the major averages started a new week by closing modestly to the downside.


Dow Jones Industrial Average

shed 28.28 points, or 0.22%, to 12,552.55, and the

Nasdaq Composite

was off 9.44 points, or 0.38%, at 2450.38. The

S&P 500

slipped 4.69 points, or 0.33%, to 1433.37.

Last week, the New York market had trouble keeping momentum, and the Dow and the Nasdaq each lost about 0.6%. Friday was especially tough for tech, as the Nasdaq slumped nearly 29 points, or 1.2%, to 2459.82.

One of the key stories of the session was a selloff in energy. Crude oil futures dropped $2.08 to $57.81 a barrel on the New York Mercantile Exchange, and natural gas plunged 60 cents to $7.23 per million British thermal units.

The steep drop came after Saudi Arabia's oil minister indicated OPEC probably wouldn't try to implement new production cuts when its member nations meet again in March.
