What is everyone’s take of a ban on insider trading? Let me start by saying that I don’t not believe insider trading is a crime, nor should it be policed by the state. But I believe there is an argument to make for it to be voluntarily banned (through contract) in order to improve the efficiency of the captial markets.
Take for example a stock exchange looking to increase liquiditiy, it could tell the firms that wish to list on its exchange - if you wish to list your stock here, your insiders must agree to not to trade based on non-public information. Of course this would be voluntary not coersed.
The logic as I see it is if insider trading is allowed investors will no longer just be speculating about the valuations of firms but also whether movements in stock prices are a result of knowledge that somebody else has that the trader doesn’t. If I own a stock and I know $40/share is the correct valuation and I see the price start dropping…37…35…31…27…I’m going to be freaking out wondering if there is information out there that I don’t have. Now i’m forced into a situation where I basically have to decide whether to sell or hold based on sheer speculation not any sound financial decision making. The result is more volitility making me less inclined to invest. Less people investing will mean higher spreads, lower stock prices, less liquidity, and slower overall economic growth.
Of course the flip side of the arguement that people make is that insider trading more quickly introduces new information to the market. But I really don’t agree with that statement, because as long as the information is not offically announced, there isn’t anything new information. Just speculation.
I agree that introducing information more quickly is a good thing, but public speculation of movements in stock price is not the same as new information.
Also, if insider trading were to be allowed, wouldn’t there be an incentive to delay the release of new information so the insiders can have time to buy or sell?
Overall, I think the quality of our captial markets would be higher if insider trading were banned and thus absent government intervention the market would move in this direction on its own.
What do you think? Agree with me? Or am I way off?
