Stock Investors Can Handle the Truth
The ban on ‘locking’ markets has the effect of hiding the best prices.

Most investors would be surprised to learn that current stock-market regulations actually prevent them from seeing and receiving the best price. Why? Well, in 2005 federal regulators at the Securities and Exchange Commission decided, in the immortal words of Jack Nicholson in “A Few Good Men,” that investors “can’t handle the truth” and that seeing true market prices would only confuse them.
Given the SEC’s willingness to conduct pilot programs to make U.S. markets more efficient and competitive, one would hope that eliminating a regulation that reduces transparency and thus harms investors would move to the top of the pilot-program list.
This can’t-handle-the-truth rule is a seemingly arcane part of the SEC’s Regulation NMS, implemented in 2007, that prohibits a market from displaying a quote that would “lock” the quote of another market. In other words, if one market is displaying, say an offer at $15.50 in IBM, IBM +0.72% then another market should not display a matching bid in IBM at $15.50.
The simple reason is that, in theory, if a bid is the same as an offer, it should result in a trade. Indeed, the stated purpose of the prohibition is that it promotes healthy interaction between buyers and sellers and contributes to a fair and orderly market. Read more of this post
