What's the index fund book everyone recommends?
In one paragraph
The Simple Path to Wealth by JL Collins. It's the most-recommended index-fund book on Reddit, in the FIRE community, and among fee-only advisors — built around one idea: own VTSAX (a total US stock market index fund) and don't touch it.
What this actually means
Collins wrote The Simple Path to Wealth as a series of letters to his daughter. That's also how it reads — direct, conversational, no jargon.
The core argument is two sentences: the stock market always goes up over long periods; almost nobody beats a total-market index fund after fees. Therefore, buy the index fund, keep buying, and ignore everything else.
Why this beats the more famous Bogleheads' Guide and Random Walk Down Wall Street as a recommendation: it's shorter (286 pages), it's funnier, and Collins explicitly tells you what to do — VTSAX in the accumulation phase, add bonds (VBTLX) in the withdrawal phase. The other index-fund books explain the theory; Collins ships an actual portfolio.
The Elements of Investing by Charley Ellis and Burton Malkiel is the strong runner-up if you want something more academic — 200 pages, written by two giants in the field, slightly more technical.
If you've already read Psychology of Money and want the next step, Simple Path is it. The two books together are 90% of what most retail investors actually need.
