Sony's results in its first quarter were something of a mixed bag -- and were not likely to affect the price of the company's shares, which remain in the doldrums, according to analysts. Bloomberg News observed that Sony shares are the worst performers this year among Japan's five largest consumer electronics makers. Sales in its film and home-entertainment division were down 11 percent from a year ago. Its best seller was the DVD version of Spider-Man 3. Profits rose substantially to $277 million, but a lot of those earnings came from such things as sales of real estate and the fact that this year it was not being forced to pay millions of dollars to replace faulty batteries in its laptop computers. Operating income, which measures how a company performs in its core units, remained in the red. A loss of 45 billion was reported.
