Stocks to watch: Sembcorp Marine, oil & gas counters

THE following developments could lead to increased stockmarket trading activity on Thursday:

Rigbuilder Sembcorp Marine's Jurong Shipyard unit has entered into a standstill agreement with North Atlantic Drilling for the delivery of the sixth generation harsh environment semi-submersible drilling rig, the West Rigel, until June 2016.

Other oil and gas counters could see more trading action after US crude oil fell below US$40 a barrel ahead of a Organization of the Petroleum Exporting Countries (Opec) meeting. Brent crude, the Europe benchmark, is near a seven-year low.
