Question on position sizing for illiquid assets and maintaining portfolio diversification
I've been trying to refine my risk management framework, especially when dealing with less liquid assets like certain private equity allocations or even some niche real estate plays. While I understand the general principles of position sizing based on portfolio volatility and individual asset risk, I'm finding it tricky to apply this robustly when exit liquidity isn't guaranteed or market prices are infrequent. How do others here approach position sizing for these types of illiquid investments while still ensuring the overall portfolio remains adequately diversified and doesn't get disproportionately skewed if one of these less tradable assets underperforms significantly?
