Stocks slipped on Monday after a choppy day of trading as investors remain uncertain about the length and depth of this recession. Technology stocks were the biggest drag on the markets, led by

IBM

(IBM) - Get Report

and

Hewlett-Packard

(HPQ) - Get Report

.

Trading continued around 12-year lows despite news of large mergers and acquisitions.

Drugmaker

Merck

(MRK) - Get Report

announced plans to acquire

Schering-Plough

(SPG) - Get Report

for $41.1 billion. The deal is expected to widen Merck's pipeline of new products and expand its international presence.

Meanwhile, trading was suspended on

Dow Chemical

( ROH) and

Rohm & Haas

( ROH) late Monday while the two companies tried to work out their $13 billion merger in court.

, including

Caterpillar

( ROH) and

Tupperware

(TUP) - Get Report

, and see what
