Who stand(s) to gain from the CEO stepping down?

Directions: Read the passage and answer the following question:

With Yang stepping down as CEO, analysts believe that it has paved the way for Yahoo to knock at Microsoft’s door with an aim to achieve the desired change as Yang was the only roadblock in Microsoft-Yahoo! Deal because he repeatedly demanded for a correct price to be paid for Yahoo. Even Kagan confirms, “As Yahoo! really wants Microsoft, therefore Microsoft will now have an easy acquisition that too on better terms than originally offered." Notably, Yahoo's shares went up by 4% the day the announcement of Yang stepping down hit the markets, which surely shows that stakeholders have welcomed the move.
