How far should brokerages go to prevent clients from buying an exchange-traded product that is essentially broken? Fidelity Investments has taken particularly far-reaching steps to shield investors from unusual price swings, in certain cases prohibiting them from staking out new positions in dozens of products. As the number of exchange-traded products nears 2,000, brokerages should more directly acknowledge their role in determining which of these aren’t suitable for self-directed investors.
