Should investors run for the doors when they see an insider hedging?

I’ve written (in Tradestream the book and on this blog) about the abnormal returns of corporate insiders.  Investors following insider moves by following corporate managers’ regulatory filings can capture some of this return.  Read more about my Insider Trading Dashboard.

Essentially, given their stature within their firms and their own profit motives, insider transactions provide relatively accurate signals as to where management sees their stock prices moving.  This strategy is predicated on mimicking insider trading moves that insiders do publicly.

But what if insiders are selling off their stock ownership by hedging their holdings less publicly (in forms 3, 4, and 5 and mostly in footnotes)?

Bettis, Bizjak, and Kalpathy recently published a study on insiders hedging their stock ownership.  In Why Do Insiders Hedge their Ownership? An Empirical Examination, the researchers describe 4 common techniques that insiders use to hedge their holdings and future stock price results depend upon which vehicle chosen:

  1. equity swaps (or total return equity swaps: insiders exchange future returns on their stock for the cash flows of another financial instrument
  2. zero-cost collars: involves a simultaneous purchase of a put and sale of a call
  3. forwards: combines a forward sale of the insider’s stock to another institution, depending upon the value of the stock at a future date
  4. exchange funds: a group of insiders place their shares in a limited partnership or LLC.  By contributing their shares into a diversified portfolio, insiders can diversify their holdings.

Intuitively, the researchers typically found a significant price run-up before these hedging transactions.  Stock performance varied depending upon which hedge was used:

  • exchange funds: stock price continued to climb
  • collars and forwards: saw a reversal in firm performance after the hedge was put on

The big takeaway here for investors is that after a significant appreciation in a heavily management-owned stock, certain hedges can signal opportunistic trading, even if no stock is formally sold.

Insider Trading Roundup: January 5, 2011

Insider Buying

Two good articles over on the Motley Fool:

  1. high momentum stock seeing significant insider buying.
    1. “To compile the list, we created a universe of 140 stocks that have seen strong gains over the last quarter. Additionally, all of these companies have had positive earnings and sales growth over the last five years. We then narrowed down the list by only focusing on those stocks that have seen insider buying over the last three months.”
  2. income stocks being bought up by insiders
    1. “It’s fair to assume that a firm’s management has a lot more access to intel than we do — so if they’re snapping up company stock, it’s a pretty good sign of things to come.”

Both these articles were written by Kapitall.  Check out their tools and the company is fresh off a significant funding round.

Insider Trading Strategy

CXO Advisory has a great piece on the evolving informativeness of insider trading (sub required) from a paper entitled “Has the Informativeness of Insider Filing Changed Post Sox? Has the Latest Credit Crunch Improved this Informativeness?” (Ashrafee Hossain).

Evidence indicates that implementation of the Sarbanes-Oxley Act and the credit crisis have both enhanced the informativeness of insider trading data as reported via SEC Form 4.
