Yahoo's largest investor doubles down

Yahoo's largest institutional investor nearly doubled its stake in the Internet search pioneer, according to a filing with the Securities and Exchange Commission on Thursday.

Capital World Investors increased its Yahoo stake to 10.1 percent, when it bumped up its ownership to 135,542,600 shares, as of March 31.

That's a 95 percent increase from its Yahoo holdings on December 31.

One possible driver that led Capital World to double down on Yahoo is Microsoft's megabillion buyout offer for the company.
