Yahoo will consider putting itself or its core businesses up for sale, with the possibilities being discussed at a series of board meetings being held later this week, according to The Wall Street Journal. The options on the table reportedly include selling off Yahoo's internet business, spinning off its shares in Alibaba, or doing both.

There have been persistent concerns about Yahoo's future, though the board has given CEO Marissa Mayer several years to work on turning it around. However, Yahoo's brightest asset remains its stake in Alibaba, which it holds 15 percent of. Yahoo has been planning to spin off its holdings of Alibaba for some time, though the plan has been delayed due to tax concerns.

Should Yahoo choose to sell off its internet business, the remaining body may be little more than a holding company for its Alibaba shares. Even if the board decides to stick with its original plan and only spin off its Alibaba holdings, that'll still leave a weaker Yahoo, and today's report signals that its board is beginning to worry about whether a turnaround is really possible. Yahoo declined to comment.
