Five things you need to know about dollar cost averaging

The Australian share market and US equities are trading at new record highs. In light of this confidence, people may be considering investing by timing the market. However, market timing never works according to the late Jack Bogle, founder of Vanguard, who invented the world’s first index fund. But Jack Bogle isn’t alone in this school of thought, Warren Buffett Agrees.

Research from countless organisations tells us, regularly investing which is known in the finance world as dollar cost averaging, helps build wealth but also reduce risk.

Here are the five things you need to know about the dollar cost averaging method:

1. What is dollar cost averaging?

It simply involves regularly investing the same amount of money into an investment, whether it be shares or managed funds.

2. Enforces discipline to investing in your future

It’s a discipled strategy that removes the emotion from a buying decision, by routinely investing set amounts, at specified intervals, say every month or week, regardless of the price or if market is up or down.

3. Evens out market fluctuations/volatility

Imagine if you bought into the Australian share market before the Donald Trump and Xi Jinping trade war began mid-2018. The market saw the biggest loss in 10 years in 2018, falling 7 per cent, its biggest drop since 2008. Now, consider if you had been averaging in (buying monthly) into a stock or the Aussie share market index (the S&P ASX200)…you would have bought most of your shares at a cheaper price to the now July all-time highs.

Research from countless organisations (including Boston College, Dalbar and AMP) tells us that investors who time the market, typically underperform those who use dollar cost averaging. And we can see this from the above example.

Dalbar’s research found that investors who time the market (over 20 years) with equity investments, underperformed the S&P500 by 4.7 per cent on average.

4. Compounding returns

Dollar cost averaging magnifies your returns and evens out market fluctuations, as the compound investing effect is multiplied.

If you are investing into your superannuation fund, regular contributions via salary-sacrifice contributions, can also magnify returns in your retirement nest egg.

5. How does it work?

Scenario 1 – no dollar cost averaging

If you invested $1,000 (as a lump sum) into an investment that returned an average 7 per cent per annum, after five years your investment would be worth $1,418.

Scenario 2 – dollar cost averaging with a capital stable investment

If you invested $1,000 (as a lump sum) into an investment that returned an average 7 per cent per annum, and invested $100 per month into the same vehicle, after five years your investment would be worth $8,577.

These basic examples show us that you would be $7,159 better offer if you regularly invested $100 per month.

Scenario 3 – dollar cost averaging into stocks

Let’s say you like the power of dollar cost averaging. But, you can’t afford to put in the extra money. Instead of investing a lump sum of $1,000, you invest $83 per month into the equity market.

If the stock price was $1.00 in the first month, you would have bought 83 shares. If the market fell in the second month and its price was now $0.50, you would have purchased 166 shares/units. At the end of the day, you would have invested more shares when the price dropped, and less shares when the stock rose.

What the greats say

[porto_blockquote]"Trying to time the market is the number one mistake to avoid". “The nice thing about investing in stock is that, over time, equities are going to do well…America is going to do well. So, you have the tide with you”. Warren Buffet[/porto_blockquote][porto_blockquote]“The bad years, the crisis years, the Dow (Jones) dropped by about 50 per cent (from Oct 2007 high of 17,078 to Feb 2009 low of 8,524.9). People panicked and got out of course, even in the mutual fund business, participially in the ETF business. (We saw) a lot of net liquidations at the lows, and now we are back. I think the gain from that level is maybe 200 per cent (as at 12 September 2018). It shows you that when you act on the emotions of the marketplace, you’re making a big mistake. I say and always have said, stay the course and don’t let these changes in the market, even a big one, that was a 50 per cent decline, don’t let that change your mind. And never never never be in or out of the market. Always be in at a certain level. You may want to be 50 per cent stocks like I am…But never be out and think you can get back in, because your emotions will defeat you totally”. (His last interview with CNBC) Jack Bogle [/porto_blockquote]

And lastly, when it comes to investing, remember what Warren Buffett says, “someone is sitting in the shade today because someone planted a tree a long time ago”.
