NEW YORK ( TheStreet) -- Best Buy ( BBY) shares fell during Thursday's trading session even after the electronics retailer announced a 7% increase to its dividend.

Best Buy said it has upped its quarterly cash dividend to 14 cents per share from 15 cents, boosting the dividend yield to 1.68% from 1.57%. The dividend announcement comes as Best Buy holds its annual meeting of shareholders in Richfield, Minn. If authorized, the increased dividend will be payable on Oct. 26 to shareholders of record as of Oct. 5.

Despite the announcement, Best Buy shares were down 98 cents, or 2.7%, to $35.65.

"This dividend further demonstrates the board of directors' and management's confidence in Medtronic's ability to generate cash and return capital to shareholders," Medtronic Chairman and CEO William Hawkins said in a statement.

Medtronic shares were slipping by 26 cents, or 0.7%, to $37.25.
