Dividends and the S&P 500

Source
The DIY Income Investor portfolio is 50% invested in high-yield dividend-paying shares. But what proportion of equity market returns are due to dividends? And should that guide our investing strategy?

As it turns out, this is quite a tricky question to answer. Of course, dividends represent 'cash-in-hand' for investors - but this cash is taken out of the businesses that generated the cash. And most companies can get a better rate of return by retaining earnings and reinvesting in the business. So, logically, companies with higher dividend yields - on average - should show slower capital or market price growth.

So what happened in the S&P 500 in the last 20 years?

This graph from Bloomberg compares two versions of market returns:
  • total market returns, including reinvested dividends
  • market returns based solely on price appreciation, with no reinvested dividends

The graph and accompanying text imply that reinvesting dividends is responsible for 43% of the  total returns of the S&P 500, which itself quadrupled over the period (+394%). That's great news, isn't it? Doesn't that reinforce your income-investing bias?

But hang on. This doesn't mean that if you bought dividend stocks you would necessarily have been better off. As described above, if you only bought dividend-paying shares you would normally expect the capital growth to be slower than for the rest of the market that doesn't pay out its cash in dividends. So, if you didn't reinvest the dividends you would be worse off.

And the graph also assumes - somewhat perversely - that reinvested dividends would be invested in the whole market, rather than just other dividend shares. So the overall return for a dividend-oriented investor could be quite different to what is shown on the graph - with an even higher proportion of gains from reinvested dividends. For more on this theme, see the retailinvestor.org website, which challenges many so-called investment 'truisms'.

So we need to be cautious how we interpret the data: there is a well-recognised tendency for people to accept evidence that supports their existing bias and ignore evidence that 'doesn't fit'.

But where does that leave us DIY Income Investors? Well, first of all, investing for income is not the Holy Grail of the stock market (although my portfolio total return in 2012 is rapidly - and unexpectedly - approaching 30%): there are many other, perfectly valid investment approaches.

However, I do think it is a practical approach for the DIY investor:
  • a focus on income forces you to think about how much income you need and what you are going to spend the money on; in other words it leads to a review of expenditure
  • a focus on yield encourages you to think about risk
  • high-yield securities, by nature are contrarian, as are most great investors
  • a 'buy and hold' investment approach incurs fewer dealing costs and requires much less time and effort that one that requires frequent interventions (i.e. to anticipate 'highs' and 'lows')
  • comparing yield makes it easier to compare different asset classes
  • investing for income prepares you for generating income in retirement

So, keep on investing for income (if you are convinced) - but be cautious how you interpret the evidence.

  1. Yield is ultimately all that matters - even for growth stocks, where the idea is that the share price is inflated to represent a high future yield adjusted to present value.

    I say, go for the yield now, and you likely get growth anyway. Go for growth it's a lottery. Yield all the way!

    Well done on the 30% BTW - beats me into a cocked hat, I thought I was doing well with 15%!

    1. Thanks TC - but I do hasten to add that this year's results in my portfolio are exceptional, and QE plays a large part in it!

  2. Tell us about that - how has QE inflated the value of your choices & which ones? Not everything going up is QE-related, you tipped Chesnara for example which did very well, but unless I miss something, it's not a QE play. Also, what will happen when (as is now unlikely to be the case for a long time) the waterfall is switched off?

    1. I'm assuming the sustained rise in the 50% of my portfolio that is fixed interest securities is due mainly to QE and a knock-on effect from gilts. Not a direct link with equities, of course, apart from the lower yields on fixed-interest pushing some investors towards high-yield equities.
