This paper addresses a situation wherein a retail investor must liquidate positions in her portfolio — consisting of assets and European options on those assets — to meet a margin call and wishes to do so with the least disruption to her portfolio. We address the problem by first generalizing the usual risk-based haircuts methodology of determining the portfolio margin requirement given the current positions of a portfolio. We derive first and second-order analytic estimates for the margin requirements given the positions. Given this generalization, we determine the liquidation strategy that minimizes the total positions liquidated and meets the margin requirement. We implement the strategy on example portfolios and show advantages over traditional piece-wise liquidation approaches. The analytic approach outlined here is more general than the margin context discussed. Our approach is applicable whenever an investor is attempting to maximize the impact of their capital subject to leverage limits and so has obviously applications to the hedge fund industry.

As a result of the Securities and Exchange Commission’s relaxation of its prohibition against the marketing of private placements, investors will soon be exposed to a broad array of syndicated commercial real estate investments. Private placement commercial real estate investments are illiquid and so cannot be easily valued by reference to frequent transactions in the same asset in active markets.

We have reviewed over 200 syndicated commercial real estate private placement memorandums and find that virtually all include projected cash flows. This study explains how investors and their advisors can use these projections to develop estimates of investment value. We determine a lower bound for discount rates applicable to the cash flows derived from commercial real estate and apply the methodology to an actual commercial real estate private placement investment. Our findings suggest significant overvaluation by commercial real estate private placement investment sponsors even when using conservative estimates of discount rates.
