"The data scientist making the numeric case for boring, consistent investing."
Nick Maggiulli is a data scientist and the Chief Operating Officer of Ritholtz Wealth Management, best known for the blog Of Dollars and Data, where he uses hard numbers to challenge conventional investing wisdom. His book, Just Keep Buying, makes an evidence-driven case for a simple, automatable investing strategy: build wealth primarily by increasing your savings rate and consistently buying assets over time, rather than trying to time the market or optimize entry points. Maggiulli's writing leans heavily on historical market data and backtesting to show that consistency beats cleverness for most investors, and that the biggest lever most people have isn't picking better investments but earning and saving more so there's more to invest in the first place.

Key Ideas & Recurring Themes
Timing the market rarely beats just buying
Maggiulli's research shows that consistently investing regardless of valuation historically outperforms waiting for the 'right' moment to buy, because time in the market matters more than timing it.
Retirees underspend more than they overspend
Contrary to the common fear of running out of money, Maggiulli cites research showing most retirees actually spend too little, leaving them wealthier but with less lived experience than they could have had.
Know what you're retiring to, not just from
Maggiulli argues that financial planning is incomplete without a clear picture of what a post-work life will actually look like, since the number alone doesn't answer that question.
