This is a tough question that requires more perspective to give a complete answer. So let me state it this way: How would you feel if you lost half the money in the stock market in a bear market? Would you panic and sell? Would you have enough other income from SS or a pension so that you could just ride it out? There’s an old saying in the stock market; “Sell down to the Sleeping Point.!” If it is keeping you awake at night, you should probably sell at least half. You definitely do need some stock market exposure to hedge against inflation down the road. But if you are going to run “off the road” in a bear market, better to have a larger cushion.
