Not sure who you are asking the question to, however, making a bunch of assumptions, the simple answer would be no. Consider 24 hours and a spot on the equator. The balloon will have a certain translational speed and if it remains at this speed while increasing height then it has further to go in order to complete one rotation of the earth (larger radius from the earth's centre). So it will land further west than it took off from, the distance being some function of the height above ground and time that the balloon is airborne for.
