I’ve adopted the buy/hold/low cost index strategy, and stuck with it for the last ~10 years, and it’s working out adequately. I’ve avoided market timing and have invested money when I’ve had it available. But recently I’ve got it in my head that’s it would be a good idea to take some % of my investments (assume 5-10%), and sell when the market hits, say, 17,800, and keep it sitting in a money market fund until the market hits, say, 15,000. That “buy point” seems conservative to me – that we could hit 15,000 again at some point in the future. I appreciate any insights into what percentage of total assets you think should be deployed (if any), and anything else that occurs to you. How much powder do you keep dry? Do you use any objective metrics for buying in? Gut instinct? Is it better just to keep the money invested (90% in stocks based on age and investment objectives), and if so why do you think that?
