| guys, not sure if i got this right but found the following that explains it. essentially, the stock repurchase was to prevent share dilution. however, given a share repurchase that the price can move up on them. to "lock in" the further shares repurchase price without spending too much $, "equity collars" were used with call and put options. i haven't been able to work out the math yet ;) so let know where you got. the dell collar would be an inverted version of the schwab link. however, without knowing the strike price of both the call/put it is rather hard to draw a payoff diagram. see the attached file and the following link. http://www.schwab.com/public/schwab/research_strategies/market_insight/investing_strategies/options/managing_risk_using_options_equity_collars.html --- On Mon, 5/2/11, Shashank Saggar <shanks...@gmail.com> wrote: |
