Module 2 · Yield, Growth & Total Return Foundation

Yield is the first number every income investor looks at and the one most likely to mislead them. This module replaces it with the two numbers that actually determine what you end up with: the growth rate of the payment, and the total return of the holding.

Calculating yield

A stock at $40 paying $0.50 quarterly — $2.00 a year — yields 5%. Two versions circulate and they can differ materially:

• Trailing yield uses the last twelve months of actual payments. Backward-looking but factual.
• Forward yield annualises the most recent payment, or uses the expected next twelve months. More current, but it assumes the dividend continues — which is precisely the assumption in question when a yield is unusually high.

Screeners are inconsistent about which they display, and some annualise a special one-time dividend as though it recurs, producing a headline yield that never existed. When a yield looks remarkable, always check the actual payment history before anything else.

The yield trap

Yield has price in the denominator, so there are exactly two ways for it to rise: the company raised the dividend, or the share price fell. The second is far more common, and it is the entire mechanism behind the yield trap.

An extreme yield is not an opportunity the market missed. It is the market pricing in a probability of a cut. Occasionally the market is wrong — that is a real, if uncommon, source of return — but the base rate runs heavily against the buyer, and establishing that requires the analysis in Modules 3 and 4, not a screener.

A practical rule: when a yield is more than roughly double its sector’s norm, treat it as a warning until proven otherwise. The first question is never “how much income is this?” but “which moved — the dividend or the price?”

The arithmetic of growth

Here is the comparison that changes how most people think about income. Two $10,000 investments:

• Stock A: 6.0% yield, no dividend growth. $600 a year, forever.
• Stock B: 2.5% yield, dividend growing 10% a year. $250 in year one.

B’s annual income overtakes A’s in year 11 and cumulative income overtakes around year 19. And that ignores the larger effect: a company growing its dividend 10% a year is usually growing its earnings at a similar rate, so B’s share price has been compounding while A’s went nowhere. Total return is not close.

Two honest qualifications. Twenty-five years is a long time to wait if you need income now — a 68-year-old and a 34-year-old should read that table completely differently. And 10% dividend growth sustained for decades is rare; the companies that actually manage it are identifiable mostly in hindsight. The point is not that growth always wins, but that the growth rate compounds and the yield does not, so a comparison based on today’s yield alone is comparing the wrong numbers.

Yield on cost

Yield on cost divides the current dividend by the price you originally paid. Buy at $20 with a $0.60 dividend and hold until the dividend reaches $2.40, and your yield on cost is 12% even though the stock now yields 3% for anyone buying today.

It is a satisfying number and a genuinely useful motivator: it makes visible what patient ownership of a growing dividend actually produces. But be clear about what it is not.

• It is not a return. Your capital is now worth the current market price, not what you paid. The relevant yield on that capital is 3%.
• It cannot be used to compare investments. Comparing your 12% yield on cost against a new holding’s 5% current yield is comparing two different denominators.
• It rewards you for the passage of time, not for judgement. Any dividend grower held long enough produces an impressive figure.
• It can justify holding something you should sell. “I’m earning 12% on my cost” is the anchoring bias from the risk course wearing an income costume. The only question that matters is whether this holding is the best use of its current market value.

Total return

The number that actually determines your outcome:

This decomposition, associated with John Bogle, is genuinely useful because it separates the durable sources of return from the temporary one. Yield and growth come from the business. Valuation change — the multiple expanding or contracting — comes from other investors’ changing willingness to pay, and it is unpredictable, mean-reverting, and dominant over short periods.

Which is why buying an excellent dividend grower at a punchy valuation still disappoints, and why the valuation work in How to Price a Stock is not a separate discipline from income investing.

Which suits you

Most sensible income portfolios hold both, and Module 9 covers how to combine them deliberately rather than by accident. The mistake to avoid is choosing between them on the basis of the yield column alone, which is what a screener sorted by yield will do to you automatically.
