Just Keep Buying
by Nick Maggiulli · 2022
Maggiulli's data-driven case that consistent, boring investing beats trying to time savings or the market.
Worth reading? Just Keep Buying earns its title: Maggiulli runs the actual numbers on saving rate versus investment returns and shows that, for most people, earning and saving more matters more than optimizing the investing itself. It's refreshingly numbers-first rather than motivational, which makes the counterintuitive findings (like why you should often keep buying stocks even near all-time highs) land harder. Skip it if you've already automated your investing and want portfolio-construction depth instead.

Book Summary
Maggiulli's data-driven case that consistent, boring investing beats trying to time savings or the market. It earns its place by using actual historical data to settle debates other books argue from intuition. For most people, increasing income and savings rate moves the needle more than optimizing investment returns. Historically, investing a lump sum immediately beats dollar-cost-averaging it in more often than not. The practical move is to read it once, then act on the one idea that maps to your current bottleneck, rereading the whole thing rarely adds more than executing the part you skipped.
