Bermuda stocks went through a topsy-turvy five days before closing in positive territory for a third successive week on Friday.

Most of the movement was brought about by the biggest domestic company on The Royal Gazette / Bermuda Stock Exchange (BSX) Index, Butterfield Bank, which plunged 50 cents to $3.50 during the first four days and bounced back up to $4 on Friday.

The rebound came after the bank announced a first-quarter loss of $20.8 million on Thursday evening.

More than 354,000 of the bank's shares changed hands, as it ended the week unchanged.

The BSX closed on Friday at 2,103.83, up 1.08 points, or 0.05 percent.

Watlington Waterworks Ltd. was the biggest winner on the BSX, shooting up $2, or 16.7 percent, to end the week on $14, on the trading of 700 shares.

Insurer Argus Group Holdings Ltd. was the only other stock to advance, gaining 10 cents, or 1.4 percent, to $7, adding to its surge the previous week, on volume of 4,500 shares.

The two largest utilities companies both fell, with Belco Holdings Ltd. slipping 25 cents, or 1.5 percent, to close the week on $16.25, while KeyTech Ltd. shed five cents, or 0.5 percent, to $9.95.

BSX volume was 421,479 and turnover was $1.58 million.
