Risk Management

The first principle of investing is that risk and return are linked. Assets that offer higher potential returns do so precisely because they carry more uncertainty. A Government of Canada bond pays little because it is nearly certain to pay you back; a junior mining stock on the TSX Venture Exchange might multiply or might go to zero, and its potential reward reflects that danger.

There is no investment that offers high returns with low risk — and anyone promising one is either mistaken or dishonest. The job of an investor is not to avoid risk entirely, which would mean accepting very low returns, but to take risk deliberately and get paid fairly for it.

Risk shows up most visibly as volatility: how much an investment's price swings up and down. A volatile holding can test your nerve and, worse, force you to sell at the bottom if you need the money at the wrong moment. That's why your time horizon matters. Money you'll need next year has no business in volatile stocks; money you won't touch for twenty years can ride out the swings.

The goal is to match the risk you take to the risk you can actually tolerate — both financially and emotionally. A portfolio that's theoretically optimal but keeps you awake at night is the wrong portfolio, because fear, not the market, is what makes most investors sell low.

Position sizing is the decision of how much of your portfolio to put into any single investment. It is the quietest and most powerful risk control you have, and most beginners ignore it.

The logic is simple. If you put 50% of your portfolio into one stock and it falls 80%, you've lost 40% of everything — a wound that takes years to heal. If that same stock is 4% of your portfolio, the same 80% collapse costs you about 3%, an annoyance you barely notice. The size of the position, not just the choice of stock, determines how much a mistake can hurt.

A common framework is to limit any single position to a small percentage of the portfolio — many investors cap individual stocks at perhaps 5% — so that being wrong about any one company is survivable. The riskier the holding, the smaller the slice. A speculative TSXV exploration stock warrants a far smaller position than a large, stable dividend payer.

Position sizing forces humility. You will be wrong about some companies — everyone is. Sizing positions so that your wrong calls are survivable, and your right calls still matter, is what lets you stay invested long enough for the math of compounding to work.

A stop-loss is a pre-set order to sell a holding if it falls to a chosen price, capping the loss without requiring you to watch the market all day. If you buy at $50 and set a stop at $42, you've decided in advance that you'll accept a roughly 16% loss rather than risk a larger one.

Stops have real benefits: they remove emotion from the exit decision and protect you from the human tendency to 'hold and hope' as a loss deepens. They also have limits. In a fast-moving market, a stop can trigger at a worse price than expected, and normal volatility can shake you out of a sound long-term holding just before it recovers. Stops suit shorter-term and more speculative positions better than long-term core holdings.

The broader idea behind a stop is drawdown control — limiting how far your portfolio can fall from its peak. Deep drawdowns are dangerous not only mathematically but psychologically: the further you're down, the more likely you are to capitulate and sell at the worst possible time.

Whichever tools you use, the principle is the same: decide your rules when you are calm, write them down, and follow them when you are not. Risk management fails most often not because the tools are weak, but because investors abandon them in the moment they're needed most.
