Every concept, endless questions
Each concept is a small financial model. Read how it works, then draw a real interview question from it: forwards, backwards or what-if, with fresh numbers and a worked solution every time.
Forward runs a concept the usual way. Inverse runs it backwards, which is what separates understanding from memorizing.
Risk Profiling
3 conceptsRisk capacity versus risk tolerance
Two different questions hide inside "how much risk should this client take?" Tolerance is psychological: how big a loss can they watch without panicking and selling at the bottom? Capacity is financial: how big a loss can the plan absorb before essential spending is no longer covered? A wealthy, nervous client has plenty of capacity and little tolerance; a bold client with a thin cushion has the reverse. The adviser’s job is to measure both and let the tighter one set the limit — because exceeding tolerance leads to bad behavior, and exceeding capacity leads to a plan that fails.
Drawdown recovery
Losses and gains are not symmetric. Fall 20% and you need 25% to get back; fall 50% and you need 100%. The deeper the hole, the faster the required gain grows, because it is earned on a smaller base. That arithmetic is the most useful thing to show a client when setting risk levels: it turns an abstract drawdown into years of waiting. Withdrawals make it much worse, because money taken out during the recovery never participates in it — which is why the same drawdown that is an inconvenience for a saver can be permanent for a retiree.
Time horizon and equity weight
Equities are risky over a year and much less risky over twenty — not because the bad years stop, but because they get averaged with good ones. The expected return piles up with time while the noise in the average return shrinks with the square root of time, so the chance that a long holding period ends in a loss falls steadily. That is the honest case for more equity when the money is not needed for decades, and the honest case against equity for money needed in two years. It is a statement about averages, though: a long horizon lowers the chance of losing, but not the size of the worst outcomes, and the dollar amount at risk still grows.
