Rival Panasonic Corp <6752.T> posted its first profit in three quarters on robust sales of advanced DVD recorders and appliances, and raised its full-year outlook.

Stocks rallied Thursday after data showed the U.S. economy returned to growth in the third quarter, brightening the outlook for profits.

The S&P 500 is up 57.6 percent from its 12-year closing low on March 9, but is off 2.9 percent from its post-March peak reached on October 19.* Going into the final trading day of the month, the S&P 500 is up nearly 1 percent for October. If the index is unable to hold onto the month's gains, it will snap a seven-month winning streak.
