TOKYO, Jan 20 (Reuters) - Japan's Nikkei average fell on Thursday as weaker-than-expected earnings by key U.S. technology and banking firms, strong Chinese growth figures and a weaker dollar prompted investors to aggressively lock in profits.
The S&P 500 suffered its biggest decline in nearly two months on Wednesday as Goldman Sachs posted a 53 percent drop in profit on a tumble in trading revenue and Wells Fargo's fourth-quarter profit came below some analysts' estimates.
Foreign investors were net buyers of Japanese equities last week for the 11th straight week, with buying at a 9-month high, data showed on Thursday, but market players said the trend could be nearing its end since the Nikkei has gained 14 percent since the start of November.
The benchmark Nikkei ended the session down 1.1 percent or 119.79 points at 10,437.31.
The broader Topix index shed 1 percent to 927.19. (Reporting by Antoni Slodkowski; Editing by Michael Watson)
