The gain disclosed Wednesday at a technology conference in San Francisco is the latest evidence of the progress that Yahoo Inc. is making under Mayer's leadership. The Sunnyvale, California, company's stock has nearly doubled since Mayer came aboard, though she and analysts say that gain primarily stems from the value of Yahoo's holdings in China's rapidly growing Alibaba Group.
