SunPower shares rose $4.70, or 5.4 percent, to $91.50 in afternoon trading.
At the same time, shares of Evergreen Solar Inc. headed in the opposite direction, losing $1.17, or 10.9 percent, at $9.60. The company narrowed its first-quarter loss to $25,000 — roughly break-even per share — compared with a loss of $6.2 million or 9 cents per share a year ago.
But investors were disappointed with Evergreen’s second-quarter guidance for a loss of 10 cents per share — below the Wall Street average forecast for a loss of 9 cents per share.
