There is an inverse question: If you have a cash windfall you want to invest, all-at-once or split it up?
I have seen a similar analysis (but can’t find it right now). Even if you invest at the all time highs, so the market drops right after you buy, you still win with the all-at-once strategy.
The general lesson: Get your money into the market as soon as possible. Maybe more memorable: Time in the market beats timing the market.
- layer8 4y agoInvesting in the stock market has the general assumption that, a priori, stocks are more likely to rise than to fall at any given point in time. Under that assumption, the all-at-once strategy has the better expected outcome. Of course, you can be unlucky and end up buying the all-time-high just before a crash. You can avoid that risk by splitting up the investment, at the cost of lowering the overall expected value. So it’s more about how you feel about that risk, and whether you feel avoiding it is worth having a somewhat lower expected return.
