Own the haystack rather than searching for a shiny needle. Market-wide funds minimize concentration mistakes, taxes, and fees, while capturing the returns businesses create collectively. Accepting average on costs often means above-average outcomes after frictions compound against frequent trading.

Basis points seem small until decades magnify them. Favor low expense ratios, tax-efficient funds, sensible account placement, and infrequent turnover. Keeping more of each dollar earned is the quietest alpha, and it never depends on predicting the next headline or hero.
