Module 9 · Building an Income Portfolio Advanced

An income portfolio built one attractive yield at a time ends up as a leveraged bet on interest rates, assembled by accident. This module is the construction discipline that prevents that — and the maintenance routine that keeps it prevented.

Define the goal first

Two portfolios that both call themselves “income” can be almost unrelated. Decide which you are building before you look at a single holding, because the answer changes every subsequent decision.

A portfolio yielding 6% is not a better version of one yielding 3% — it is a different portfolio, holding different companies, with different failure modes. Most people building “income” portfolios in their forties are actually building income-later portfolios and buying income-now holdings, and the mismatch costs them the compounding in the Module 2 table.

Core and satellite

A structure that has held up well, expressed as a share of the income sleeve rather than of your whole net worth:

Each satellite is sized by the risk-budget method: the maximum portfolio loss you accept from one name being wrong, divided by its plausible decline. For a large, well-covered dividend payer that might be 45–55%; a 1.5% risk budget therefore produces a position of roughly 3%. Twelve such positions is 36% — already above the satellite cap, which is the arithmetic telling you that twelve names is too many to research properly anyway.

Caps that bind

Income portfolios concentrate themselves. The highest yields cluster in the same four or five sectors, so a portfolio assembled by picking attractive yields ends up in financials, utilities, telecoms, pipelines and REITs — every one of them primarily driven by interest rates.

The working set of caps:

• Single company: 5% at purchase, trim above 8%. Including the look-through weight inside your ETFs, which is the part people forget.
• Single sector: 20–25%, measured across individual holdings and funds together.
• All rate-sensitive holdings combined: 45–55%.
• Canada: 40% or less of equity exposure, despite the tax advantage of Canadian dividends. Module 5’s tax logic is a reason to hold Canadian dividends in taxable accounts, not a reason to hold only Canadian dividends.
• Specialist / high-yield products: 15% combined.

The yield-and-growth barbell

Rather than hunting for a single holding that offers both a high yield and fast growth — a combination that mostly exists in marketing material — hold both types deliberately and let the blend produce the portfolio yield you need.

This is the single most useful construction idea in the module, and it generalises: whenever you need a portfolio-level number, ask whether it is better achieved by a blend of two things you understand than by one thing that claims to do both.

DRIPs

A dividend reinvestment plan automatically uses your distributions to buy more shares. Two versions exist and the difference matters.

• Full (company-operated) DRIP. Run by the company’s transfer agent. Buys fractional shares, so every cent is reinvested, and some Canadian companies offer a discount — typically 2–5% off the market price. Requires holding shares in registered form or a broker that supports the plan.
• Synthetic (broker) DRIP. Offered by most brokerages, free, and applies to most listed securities. Buys whole shares only, so the remainder stays as cash. No discount.

Reinvesting is powerful for an accumulator: it compounds the payment stream automatically and removes a decision you would otherwise make imperfectly. But there are three cases where it is the wrong choice.

1. It breaks your caps. A DRIP mechanically buys more of whatever you already own most of, including holdings already above their limit. Automatic reinvestment is automatic concentration if you do not check.
2. You are reinvesting into a deteriorating holding. The DRIP does not read the cash flow statement. A company failing the Module 3 scorecard should not be receiving new money from you every quarter by default.
3. You have a taxable account and a cost-base problem. Every reinvestment is a new purchase at a new price, so your adjusted cost base becomes a running calculation. Combined with the return-of-capital tracking from Module 7, this gets genuinely painful. Keep the records as you go.

Where new money goes

The most efficient rebalancing tool available to anyone still contributing: direct all new contributions, and optionally all distributions, to the most underweight sleeve. No sale, so no trading cost and no tax event, and the portfolio drifts back toward target on its own.

This resolves several problems at once. It stops winners from growing past their caps without you having to sell them. It naturally buys more of whatever has lagged, which is the behaviour everyone endorses and few execute. And in a taxable account, it makes the difference between rebalancing being nearly free and rebalancing costing you a realised gain.

The practical version: turn off automatic DRIP on holdings at or above their target weight, let those distributions accumulate as cash, and deploy the cash quarterly into whatever is furthest below target.

The quarterly review

Fifteen minutes, four times a year. Not more often — monitoring an income portfolio weekly produces action, and most action is a cost.

1. Any dividend changes? Raises, freezes and cuts across every holding. A freeze is the signal from Module 4 that deserves attention.
2. Any holding above its cap? Including look-through weights in your funds. Trim or redirect new money.
3. Rate-sensitive total. The one that creeps upward without anyone deciding it should.
4. Payout coverage on the satellites. Pull the latest FCF payout or AFFO payout for each individual holding. This is where a problem shows up first.
5. Portfolio yield and total income in dollars. Track the dollars, not the yield. Rising yield with falling dollar income means prices fell, and it is the exact signal a yield figure hides.
6. Anything that has fallen more than 25%? Not to sell reflexively, but to check whether a thesis broke while you were not looking.
