Optimal Liquidation of Derivative Portfolios

Abstract: We consider the problem facing a risk-averse agent who seeks to liquidate or exercise a portfolio of (infinitely divisible) perpetual American-style options on a single underlying asset. The optimal liquidation strategy is of threshold form and can be characterized explicitly as the solution of a calculus of variations problem. Apart from a possible initial exercise of a tranche of options, the optimal behavior involves liquidating the portfolio in infinitesimal amounts, but at times which are singular with re… Show more

“…If at some time it is not the first-to-be-exercised, thresholds for all options exercised before it, including the first-to-be-exercised, are reduced since the portfolio remaining after their exercise now includes the new option. 44 We know for a single grant of identical options, as the number of options becomes infinite, the individual exercise thresholds will limit to the option strike K, see Henderson and Hobson (2011).…”
