Index and Hold

Own the whole market through low-cost index funds and hold for decades. Costs are certain while returns are not — so minimize the costs. 'Don't look for the needle in the haystack. Just buy the haystack.'

Quality at a Fair Price

Buy wonderful businesses with durable moats and able management, then hold them. 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

Invest in What You Know

Pay attention to businesses you understand from everyday life, do the homework on their fundamentals, and give winners time to grow. 'The real key to making money in stocks is not to get scared out of them.'

Return on Invested Capital (ROIC)

How much profit a company generates per dollar of capital it employs.

ROIC measures how efficiently a business turns invested capital into profit. When a company can sustain ROIC above its cost of capital and reinvest at those rates, it compounds value for owners. Consistently high ROIC is one of the strongest signals of a durable, high-quality business.

Free Cash Flow (FCF)

Cash left over after running and maintaining the business.

Free cash flow is the cash a company generates after paying for operations and capital expenditures. Unlike accounting earnings, it's hard to fake, and it's what ultimately funds dividends, buybacks, debt paydown, and reinvestment. Growing FCF per share is a hallmark of a compounding machine.

Economic Moat

A durable competitive advantage that protects long-term profits.

Coined by Warren Buffett, a 'moat' is a structural advantage — network effects, switching costs, scale, brand, intangibles, or cost advantage — that lets a company fend off competitors and earn high returns for years. Moats are why some businesses can compound for decades while others see their profits competed away.

Payout Ratio

The share of earnings paid out as dividends.

A lower payout ratio means a company retains more earnings to reinvest and has more room to keep raising its dividend. A very high payout ratio can signal that future dividend growth will be limited or that the dividend is at risk if earnings dip.

Expense Ratio

The annual fee a fund charges, as a percentage of assets.

A fund's expense ratio is deducted every year, so it compounds against you. The difference between a 0.03% and a 0.50% fund sounds tiny but, over 30 years, can cost a meaningful share of your ending wealth. Minimizing fees is one of the few levers an investor fully controls.

Tracking Error

How closely an index fund follows its benchmark.

Tracking error measures the gap between a fund's returns and the index it aims to replicate. For passive index funds you generally want this as low as possible — large tracking error means you're not getting the exposure you signed up for.

Dollar-Cost Averaging (DCA)

Investing a fixed amount on a regular schedule, regardless of price.

By investing the same amount at regular intervals, you buy more shares when prices are low and fewer when high, smoothing out your average cost and removing the temptation to time the market. For long-horizon investors, consistent contributions matter far more than entry timing.

Compounding

Earning returns on your prior returns — growth that accelerates over time.

Compounding is the engine of long-term wealth: each year's gains generate their own gains. Its power is back-loaded — most of the growth happens in the final years of a long horizon. That's why time in the market, started early, usually beats trying to time the market.

Diversification

Spreading risk across many holdings so no single one can sink you.

Diversification reduces the impact of any one company or sector failing. Broad index funds diversify across hundreds or thousands of companies at near-zero cost. It won't eliminate market risk, but it removes the uncompensated risk of concentration.

Tax-Advantaged Accounts

Accounts like 401(k)s and IRAs that shelter investment growth from taxes.

Accounts such as 401(k)s, Traditional IRAs, and Roth IRAs let investments grow tax-deferred or tax-free, which dramatically boosts long-term compounding. Using available tax-advantaged space before taxable accounts is one of the highest-impact moves for long-horizon investors. (This is general education, not tax advice.)
