Wards Co. Inc., operators of Circuit City, Dixie, Lafayette and other discount electronics chains, reported a 449 percent increase in its second-quarter profits of $434,000 (21 cents per share), compared with $79,000 (four cents) last year.

Wards President Alan L. Wurtzel attributed the gain, particularly in the video and electronics products divisions, to "improved acquisition costs of merchandise as a result of the opportunistic buys available in this soft economy." Profits also benefited from lower interest rates and borrowing levels for working capital, Wurtzel said.

Second-quarter sales were $49 million, a 31 percent increase over last year's $37 million.

Dixie stores in Winston-Salem and Fayetteville, N.C., and licensed departments in Haynes furniture stores in Virginia Beach and Hampton, Va., were closed as planned during the quarter. A new Circuit City store in Fayetteville and new Superstores were opened in Winston-Salem and Virginia Beach. The company also opened licensed departments in Zody's stores in Ceres and Riverside, Calif.

Net income for the fiscal year ended Aug. 31 was $6.26 million ($2.40), compared with $6.12 million ($2.78) for fiscal 1981.
