Microsoft, like most companies with publicly traded stock, tries to maintain the price of its shares below $100. To do so, the company has split its stock in 1987, 1990, 19991, 1992, 1994, 1996, 1998, 1999 and 2003.
For shareholders who had previously owned shares, Microsoft´s stock splits have offered a variety of options. For the most part, the splits have been two for one. This means that for every share that was held before the split, the stockholder would own two after the change.Learn more about Investing
