Trading in DEC shares had to be halted on the New York Stock Exchange for a time yesterday lunchtime to prevent a disorderly market as the company announced that it planned to bolster the price by buying in up to 10m of its shares, representing about 8% of the total – effectively another way of paying shareholders a dividend. The response was muted when trading resumed, and at 2.07pm New York time, the price was up 1.875 at $90.625 on the day.
