| read somewhere, not sure the source, that rules of thumb is if annual cash need = 1-2% nominal pre tax , then you can take above average risk. Here it is above 5%, not a trivial number since you may be forced to liquidate 5% in a down market to meet this need – can never catch up – not able to tolerate too much volatility. |
