How To Invest With Dollar Cost Averaging In Australia

Dollar cost averaging is a strategy to manage price risk when you’re buying stocks, exchange-traded funds (ETFs) or managed funds. Instead of purchasing shares at a single price point, with dollar cost averaging you buy in smaller amounts at regular intervals, regardless of price.

When investors purchase securities over time at regular intervals, they decrease the risk of paying too much before market prices drop. It also helps spread the cost out over time.

Prices don’t only move one way, of course. But if you divide up your purchase and make multiple buys, you maximise your chances of paying a lower average price over the long-term. In addition, dollar cost averaging helps you get your money to work on a consistent basis, which is a key factor for long-term investment growth.

Chances are you are probably already taking part in dollar cost averaging via your superannuation fund, which invests money over a long period of time, regardless of the market conditions.

Dollar cost averaging takes the emotion out of investing by having you purchase the same small amount of an asset regularly. This means you buy fewer shares when prices are high and more when prices are low.

Say you plan to invest $1,200 in Managed Fund A this year. You have two choices: you can invest all of your money at once at the beginning or the end of the year—or you can invest $100 each month.

While it might not seem like choosing one approach or the other would make much of a difference, if you spread out your purchases in $100 monthly portions over 12 months, you may end up with more shares than you would if you bought everything at once. Consider this hypothetical 12-month result:

In the example above, you would end up saving 42 cents a share by spreading out your investments over 12 months instead of investing all of your money one time.

• If you bought $1,200 worth of Managed Fund A at a price of $10 per share in January or December, you would own 120 shares.
• If you bought $100 worth of Managed Fund A per month for 12 months, your average price per share would be $9.58, and you would own 125.24 shares.

In this example, dollar cost averaging buys you more shares at a lower price per share. When Managed Fund A increases in value over the long term, you’ll benefit from owning more shares.

Dollar cost averaging works because over the long term, asset prices tend to rise. But asset prices do not rise consistently over the near term. Instead, they run to short-term highs and lows that may not follow any predictable pattern.

Many people have attempted to time the market and buy assets when their prices appear to be low. This sounds easy enough, in theory. In practice, it’s almost impossible—even for professional stock pickers—to determine how the market will move over the short term. Today’s low could be a relatively high price next week. And this week’s high might look like a fairly low price a month from now.

It’s only in retrospect that you can identify what favourable prices would have been for any given asset—and by then, it’s too late to buy. When you wait on the sidelines and attempt to time your asset purchase, you frequently end up buying at a price that’s plateaued after the asset has already made big gains.

And trying to time the market can really cost you. According to US research by Charles Schwab, investors who tried to time the market saw drastically less gains than those who regularly invested with dollar cost averaging. It’s a similar story in Australia. Investment house, Morningstar Australia, ran some numbers and found that a buy-and-hold strategy outperformed market timing by 10% cumulatively or just less than 1% a year.

From a practical standpoint, dollar cost averaging helps you begin investing with small amounts of money.

You may not, for example, have a large sum to invest all at once. Dollar cost averaging gets smaller amounts of your money into the market regularly. This way, you don’t have to wait until you have a larger amount saved up to benefit from market growth.

Dollar cost averaging’s regular investments also ensure you invest even when the market is down. For some people, maintaining investments during market dips can be intimidating. However, if you stop investing or withdraw your existing investments in down markets, you risk missing out on future growth.

Those who remain invested during bear markets, for instance, historically have seen better returns than those who withdraw their money and then try to time a market return, according to the Charles Schwab research.

In this way, dollar cost averaging is perfect for beginners: those, in other words, with less money and who may be nervous about riding out market highs and lows.

Outside of hypothetical examples, dollar cost averaging doesn’t always play out neatly. In fact, research from Vanguard has found that over the very long term, dollar cost averaging can underperform lump sum investing. Therefore, if you do have a large sum of money, you’re generally better off investing it as soon as possible.

But don’t take this research at face value. You may not have a large amount of money saved up—and waiting may cause you to miss out on potential gains. It can be stressful to invest a lot of money at once, and it may be easier psychologically for you to invest portions of a large sum over time.

In addition, dollar cost averaging still helps your money grow. In Vanguard’s research, investors who used dollar cost averaging did see significant investment growth—just slightly less most of the time than if they had invested a lump sum.

Also, keep in mind that lump sum investing only beats dollar cost averaging most of the time. A third of the time, dollar cost averaging outperformed lump sum investing. Because it’s impossible to predict future market drops, dollar cost averaging offers solid returns while reducing the risk you end up in the 33.33% of cases where lump sum investing falters.

You might consider dollar cost averaging if you’re:

• Beginning to invest and only have smaller amounts to buy shares.
• Not interested in all the research that goes along with market timing.
• Unlikely to keep investing in down markets.

You might prefer another investment strategy if:

• You have a large sum to invest.
• You enjoy trying to time the market and don’t mind the extra time and research.
• You’re investing for the short term.
