Setting Your Investment Goals and Time Horizon
If someone asks 'Why do you invest?', it's easy to answer 'To make money.' But that's not a goal. Only once you decide when you'll use the money can you decide how to grow it.
The Goal Determines the Strategy
Even the same amount, about $740, should be grown completely differently as 'a rental deposit needed in 3 years' versus 'retirement money needed in 30 years.'
If it's money you absolutely must use in 3 years, and a -30% drawdown comes in the meantime, there's no time to recover. So money for a short horizon is best held mostly in safe assets. Conversely, if it's money you'll use in 30 years, you have enough time to recover even if a few big drawdowns come along the way, so you can afford to raise the weight of risky assets like stocks.
In other words, 'when you'll use the money (the horizon)' and 'how much you need (the target amount)' must be decided first, and only then does 'which assets to hold and how much (asset allocation)' logically follow. It shouldn't be the other way around.
If you chase only 'high returns' without a goal, you risk being in a loss right when you need the money. The key point is that the horizon determines the strategy.
Turning a Goal into a Concrete Number
A good goal is concrete, not vague. Not 'become rich' but 'save about $37,000 in 10 years,' with an amount and a deadline attached.
This lets you work backward. Once the target amount and horizon are set, you can figure out 'how much per month, at what annual return, do I need to grow this to reach it.' And you can judge whether that required return is realistic (for example, whether it's achievable with safe assets alone, or whether risky assets are needed).
One thing to watch: you also have to account for inflation. About $37,000 ten years from now buys less than about $37,000 does today. So it's more accurate to think of the target amount in terms of 'future real purchasing power.'
If the required return comes out unrealistically high (for example, 30% every year), lowering the target amount, extending the horizon, or increasing how much you save is safer than taking on excessive risk.
常见问题
Q. Can I set multiple goals?
That's actually the natural thing to do. Emergency fund (short-term), marriage or buying a home (mid-term), retirement (long-term)—each goal has a different horizon. It's best to split each goal into a separate pocket and apply asset allocation that fits its horizon. The shorter the goal, the safer; the longer the goal, the more room to raise the weight of risky assets.
Q. How do I set a target return?
It's right to work backward from the 'return needed to achieve the goal,' not the 'return you want.' If the required return is low, there's no reason to take on big risk; if it's high, you have to take on more risk or adjust the goal or horizon. Refer to the long-term historical returns of each asset, but remember there's no guarantee the future will be like the past.
