The Oslo bourse ended an automatic matching halt of shares in oil and gas services firm Aker Maritime on Tuesday after an investigation of a 13.4 percent rise in the share price.
"The Oslo Stock Exchange has reviewed the price movements. Matching halt ends," it said after an about 30 minutes halt.
It had ordered an automatic matching halt of the share to investigate a sharp 9 crowns rise to 76 in the stock price. It slipped slightly to 74.5 crowns just after automatic matching resumed.
