We develop the idea of using Monte Carlo sampling of random portfolios to solve portfolio investment problems. We explore the need for more general optimization tools, and consider the means by which constrained random portfolios may be generated. DeVroye's approach to sampling the interior of a...

We identify a feedback loop between fire sales and equity option returns. The demand effect of fire sales induced by mutual fund extreme outflows decreases delta-hedged put option returns by 4-10% per year and increases the expensiveness by 2.5%. We address endogenous concerns using instrumental...
