Liquidity measures how quickly you can turn your assets into cash. If you don't have liquidity, you can't use your assets to achieve your goals. You should have enough assets in cash and cash equivalents to cover a 3-6 month emergency fund and pay for any major goals you hope to achieve this year.
Review your coming goals for the year and make sure you have sufficient liquid assets to achieve them. If you don't, start selling assets using the same dollar cost averaging technique you used to buy them.
