On Thursday, Sony executives spoiled the holiday cheer of Japan's Golden Week. For the second time in four months, the Japanese electronics giant announced it had been way too optimistic about its chances of ending its losing streak. The company said its net loss for the fiscal year ended in March was 130 billion yen ($1.3 billion). The Japanese stock market took the bad news in stride. In early trading today, Sony shares fell as much as 4.4%, the biggest intraday decline since November 1, but by the end of Friday they had pared losses to just 0.5%. Sony has yet to take the biggest step: finally throwing in the towel on its television business.
