Single stock futures and promoter share pledges

I participated in a discussion on CNBC TV18 about the trading of single stock futures on companies whose promoters have pledged a significant portion of their shareholding. (You can watch this show here(Part 10) though I participated only by audio).

The discussion was about a proposal that companies whose promoters have pledged a significant fraction of their shareholding should be punished by stopping trading in single stock futures in the shares of these companies. My views were as follows:

  1. Allowing trading of single stock futures should not be seen as a mark of prestige for the company or any form of a reward or seal of approval. The single stock future exists to meet the need of investors and not the needs of the companies or of the exchanges.
  2. Single stock futures are the easiest way to short shares, and so banning single stock futures would be a mild form of banning short selling. Short selling is an absolutely essential counterweight for the leveraged long. Restricting short selling when the promoters are leveraged long would essentially be a way of bailing them out and protecting them from sharp falls in their share prices.
  3. Large leveraged longs create a cliff risk for the share price – if the price falls far enough to produce large margin calls for the leveraged buyers, then the price can just fall off a cliff due to distress liquidation of the pledged shares by the lenders. The answer to this is more stringent margins when cliff risk is high either because of a large leveraged long position (or on the opposite side, because of a large short interest).

    I do not know whether it’s just me or if everybody else encountering issues with your website. It looks like some of the written text in your posts are running off the screen. Can somebody else please provide feedback and let me know if this is happening to them as well? This might be a issue with my internet browser because I’ve had
    this happen previously. Kudos

    Hello, I think your website might be having browser compatibility issues.
    When I look at your website in Firefox, it looks fine but when opening in Internet Explorer, it has some
    overlapping. I just wanted to give you a quick heads up!
    Other then that, superb blog!

    Currently it looks like Expression Engine is the best blogging platform
    out there right now. (from what I’ve read) Is that what you’re
    using on your blog?
