That’s why the best solution is to eliminate insiders. Make companies post product sales information more often—every day or even in real time. Spray investors with a fire hose of information. A great model is WisdomTree, a manager of exchange-traded funds. Every day on its investor-relations Web page, the firm posts assets under management and average fees and so anyone who can use a calculator can figure out revenues. Voilà: no insiders.
