Not All Index Are Created Equal

I think most of us are using Index as bench-marking against our portfolio’s performance and from time to time, we often hear about buying index as a kind of passive investment. Some financial advisors are even proposing “DCA” or dollar-cost averaging for Index with “buy and hold” strategy.

“The average annualized total return for the S&P 500 index over the past 90 years is 9.8 %.”

Guess this is the most “eye-catching” a phrase that often mentioned in the news which is also the most powerful words to attract investors pouring billions of dollars into Index ETFs under the so called a “passive investment” strategy.

But remember that not all Index are created equal if the index is added with many “toxic stocks”, such an index will sure underperform than other world indexes.


Look at the chart, If you are a fresh graduate who has invested $10K into STI Index fund 5 years ago, locking it with “buy and hold “ strategy, guess what, your returns will be quite pathetic with negative returns of -5.28% (excluding dividend). With dividend added, you returns may increase to about 2.5%+/- p.a.

If we compared such returns with 10 Bond yield, it only gave us 0.5%+/- over Market (Equity)  Risk Premium “ on the average for the past 5 years, which I think is very low as to take higher risk by investing in Equity vs Bond.

What is “Market Risk Premium”? < source :>

Below are two very good and well-written articles on investing in STI Index as passive investment.

3 Reasons Why Singapore’s STI (‘Super Terrible Index’) is a Bad Passive Investment Strategy <>

Obviously, the Banks (with much higher weightage due to larger market cap ) and REITs in STI Index which performed well in the past few years had assisted to deter the index from ending up at a much lower level as of today.

Index investing is about diversification and of course is good to have an index which diversify across different industries and stocks in order to manage risk ( unsystematic risk) and reduce volatility.

The Big 3 Banks (especially DBS) which contributed almost 38% (DBS-15.9% / OCBC-11.3%, UOB-10.6%) of market cap weightage is holding the index well due to good performance and strong recovery from GFC, else, just look at how badly the other stocks listed in STI Index perform from the below charts.

It’s not surprising that so many people like the idea of “passive investing” in Index as you can imagine that having a portfolio that making money for you while you are sleeping, “ buy and hold” without much worry about market volatility and keep it for long term.

Well, 5 years may be too short to see the result as we invest for the long term, how about stretch our investment horizon to a much longer period?

We will also need to take note that past 30 years and next 30 years returns will be much different as Singapore’s economic structure had changed, we experienced high GDP growth in early 70/80s, but look at the economy growth for the past 5 years is rather low or stagnant. Diminishing returns for STI will continue in line with GDP growth unless we include more company with international exposure into STI Index.

With current STI skewed towards Big 3 banks with as much as 38% weightage, imagine if banks stock collapse, do you think others can come to rescue?

This is the predicament of the current STI Index. Maybe we should ask President Trump on how to
