Do I need to read The Intelligent Investor to invest in index funds?
In one paragraph
No. The Intelligent Investor teaches stock-picking — a discipline index-fund investors deliberately don't practice. If your plan is buy-and-hold an S&P 500 or total-market fund, The Simple Path to Wealth is the one book you actually need.
What this actually means
Graham's book is about analyzing individual companies — reading 10-Ks, calculating intrinsic value, hunting for stocks trading below a margin of safety. None of that applies to someone buying VTSAX or VOO every payday.
The Simple Path to Wealth by JL Collins is the right book for index-fund investors. It explains why index funds beat almost all active managers after fees, gives you an actual portfolio (VTSAX in accumulation, add VBTLX before retirement), and stops there. 286 pages.
Pair it with The Psychology of Money. Housel teaches the behavioral discipline — don't sell in a crash, ignore the news, stay invested for decades — that determines whether your index strategy actually works. Index investing is a behavior problem, not a knowledge problem.
Intelligent Investor is worth reading later if you become genuinely curious about stock-picking or value investing. But making it a prerequisite is like requiring a course in engine mechanics before you're allowed to drive a Toyota. Buying an index fund is supposed to be simple. The books should be too.
