What is the advantage of owning stock which has voting rights? These guys (the first 20 posts, specifically comment #17) imply that stock which has voting rights will trade at a premium. Furthermore, this Berkshire memo mentions that there will fluctuation and difference in supply and demand between two types of stock that have a constant valuation ratio despite having differing voting rights.
