A 30-year-old and a 60-year-old investor have identical risk tolerance scores on a questionnaire. According to sound asset allocation principles, should they hold the same stock-to-bond ratio?
AYes — risk tolerance is the only factor that determines the correct asset allocation
BNo — the 30-year-old should hold more stocks due to a longer time horizon to recover from downturns
CNo — the 60-year-old should hold more stocks to accelerate wealth accumulation before retirement
DYes — both should hold a 60/40 split, which is the standard balanced allocation for all investors
Time horizon is a separate and dominant factor in asset allocation. A 30-year-old hit by a 40% market crash has decades to recover; a 60-year-old facing the same crash near retirement could see permanent damage to their income. Even identical risk tolerance doesn't override this asymmetry. A common rule of thumb (stock % ≈ 110 minus your age) formalizes the idea that allocations should shift toward capital preservation as the need for the money approaches.
Question 2 Multiple Choice
A portfolio that started at 60% stocks / 40% bonds is now 70% stocks / 30% bonds after a strong equity year. Rebalancing back to 60/40 requires:
ABuying more stocks and selling bonds, since the rising asset should be reinforced
BSelling stocks and buying bonds, which mechanically enforces selling high and buying low
CAdding new contributions equally to all asset classes until balance is restored
DWaiting for stocks to fall naturally back to 60% before taking action
Rebalancing means selling what has grown above target and buying what has fallen below target — in this case, selling stocks (now overweight) and buying bonds (now underweight). This is mechanically 'sell high, buy low,' which is precisely what disciplined investing requires but emotion makes difficult. Without a rebalancing discipline, portfolios drift toward higher-risk allocations after bull markets — exactly when many investors feel most comfortable and least likely to notice the drift.
Question 3 True / False
Adding bonds to an all-stock portfolio can reduce overall portfolio volatility even when bonds have lower expected returns than stocks.
TTrue
FFalse
Answer: True
Bonds often move differently from stocks — in recessions, investors frequently flee to high-quality bonds, causing them to hold value or rise while stocks fall. This negative or low correlation means that combining assets reduces the combined volatility below what either asset has alone, even if bonds individually have lower expected returns. This is the mathematical core of diversification: uncorrelated or negatively correlated assets smooth the ride even if they drag average returns slightly.
Question 4 True / False
A young investor with a long time horizon has no meaningful need to worry about asset allocation — they should simply hold 100% stocks since time eliminates investment risk.
TTrue
FFalse
Answer: False
Time horizon reduces but does not eliminate investment risk. Even long-horizon investors face behavioral risk (panic-selling during crashes and locking in losses), unexpected liquidity needs (job loss, medical emergencies), and sequence-of-returns risk. Moreover, 'long time horizon' is relative — a 25-year-old planning to retire at 65 has 40 years, but life rarely goes exactly to plan. A 10–20% bond allocation even for young investors provides a rebalancing buffer and emotional anchor. The claim that time 'eliminates' risk overstates the case significantly.
Question 5 Short Answer
Explain why time horizon, not just risk tolerance, should be a dominant factor in asset allocation decisions.
Think about your answer, then reveal below.
Model answer: Time horizon determines how long an investor has to recover from market downturns. Stocks are volatile year-to-year but have historically grown over decades; a long horizon makes temporary crashes economically survivable. Risk tolerance measures willingness to endure volatility; time horizon measures the actual financial consequences if that volatility strikes at the wrong moment. A risk-tolerant retiree who holds 90% stocks and faces a 40% crash cannot wait 10 years for recovery — they need income now. Even identical psychological willingness to absorb losses does not override the difference in economic vulnerability between a 30-year-old and a 60-year-old.
The deeper point is that risk tolerance and time horizon measure different things. Tolerance is psychological; time horizon is structural. A full asset allocation framework requires both: choose an allocation aggressive enough to grow toward your goals but conservative enough that a major drawdown near the withdrawal date doesn't derail them. Time horizon is the primary structural constraint; risk tolerance determines the latitude within that constraint.
