Illiquidity: Implications for investors and pension funds

Liquidity has become one of the most heavily discussed and researched aspects of financial markets.

Illiquidity is a multi-dimensional concept, reflecting at least a time, volume and price dimension. This affects the optimal portfolio composition.
