DCA (Dollar Cost Averaging) on S&P 500 over the past 20 years

How much would a PAC on the S&P 500 have returned over the past 20 years?

Let’s look today at a Capital Accumulation Plan on an all US equity portfolio, specifically on the S&P500 index. To simulate this investment plan with Wallible instruments we make the following choices:

  • initial investment of €5,000
  • periodic monthly investment of €500

We see that over the long term the high risk, quantifiable with a volatility of 19.7% of the portfolio, has returned a considerable profit of around 250% (11.5% annualised). Thus, against an accumulated investment of 125k€, the current value stands at about half a million. Over the long term, the beneficial effect of compound interest can also be seen, the right-hand side of the graph showing an exponential departure of the portfolio value curve (brown) and invested capital (green). We also note how the maximum drawdown during the sub-prime crisis is -46%.

The importance of the PAC, in addition to allowing investment with small capital, which is accumulated over time, is that of mediating the purchase price by buying shares every predetermined period (in the example seen: monthly).
