If you do not have anyting in writing concerning the terms of your agreement to transfer the company, its very difficult to answer this question. If your business is incorporated or an LLC, the business statutes might provide some guideance on governance issues. I doubt you can get the "stock" back just b/c you disagree on business decisions but you may have a voice in what those decisions are. Tough situation without anything in writing.
