Saving goal

Investing a lump sum

An inheritance, a bonus or a sale can leave you with capital to invest all at once, rather than building it up month by month. The real question is rarely whether to invest it, but how.

Investing a lump sum

When the money is already there

All at once, or in stages

A lump sum can be invested immediately or spread out over a few months. Both approaches have their merits, and the choice comes down more to how you handle risk than to what statistically performs best.

Investing immediately
Statistically, investing immediately tends to deliver a better outcome, since markets have historically risen more often than they have fallen.
Spreading it out
Spreading the purchase over a few months smooths out the risk and can feel more comfortable, especially with a large amount.
The same principle as other saving
Whichever way you invest the lump sum, the same principle applies: a long time horizon gives you room to ride out volatility.

How to invest a lump sum

A lump sum often raises one particular question: all at once, or spread out over time?

Investing immediately, statistically speaking
Since markets have historically risen over most periods, investing immediately tends to outperform waiting or spreading out the purchase. The longer you wait to invest, the longer your money is out of the market.
Spreading it out for peace of mind
Splitting the amount into, say, three to six parts over as many months reduces the risk of investing right before a downturn. The cost is that part of the capital sits outside the market for a while.
The size of the amount matters
The larger the amount relative to your total wealth, the more reasonable it can be to spread out the investment, even though it statistically costs something in expected return.
The time horizon matters more than the timing
Whichever way the amount is invested, the time horizon matters more for the end result than exactly when the purchase happens.

Worth considering

Three questions before you invest

Before putting in a larger amount, it is worth having answers to these three questions.

01

How long is your horizon?

A lump sum that will stay invested for 10 years or more supports a higher share of equities than one you might need in a couple of years.

02

Do you already have a buffer?

A cash buffer for unexpected expenses should exist alongside the capital invested for the long term.

03

All at once, or spread out?

Both are reasonable choices. What matters is that the amount actually gets invested, not finding the perfect moment.
