Description

You don’t need to pick stocks, time the market, or pay an advisor 1% to build serious wealth — you need three low-cost index funds and the discipline to leave them alone. This is the complete case for the 3-fund portfolio: why simple beats clever (over 20 years, ~93% of active funds lose to the index), how to build it, how fees quietly consume a quarter of your wealth, how to set your allocation, why rebalancing forces you to buy low, and how to beat the behavior gap that sabotages most investors. The cheapest book in the library, because everyone deserves to know this.
