"One measure for promoting both stability and fairness across financial market segments is a small sales tax on all financial transactions - what has come to be known as a Robin Hood Tax. This tax would raise the costs of short-term speculative trading and therefore discourage speculation. At the same time, the tax will not discourage "patient" investors who intend to hold their assets for longer time periods, since, unlike the speculators, they will be trading infrequently."
