The Securities Industry and Financial Markets Association, an important Wall Street lobbying group, has decided to support the Obama administration’s proposal to hold brokers to the same standard as a fiduciary when they provide investment advice, according to a recent report in The Wall Street Journal. While investors who sue their brokers have long argued, with considerable success, that a fiduciary duty arises whenever there is a relationship of trust and confidence between broker and investor, that determination is presently made on a case by case basis under laws that vary from state to state. A federal standard, which is more likely to pass now that it has been endorsed by the industry, would make it easier for investors to prevail in claims against brokers.
