STI reached All-Time High

Since my previous posts (part 1 here, part 2 here, part 3 here) on calculating my returns from investing in STI over the last 10 years, the STI continued its good run. In fact, it is has reached all-time high of 4005 as of today 28 Mar 2025, though it didn't close above 4000 today. 

So I decided to write another feel-good post about my returns from investing in STI, which should be higher than the 6.4% CAGR reported in my previous post. 

I have collected $22,909.18 in dividends over the last 10+ years. I started DCA on 24 Apr 2014. 

So how much returns has that netted me?

Without dividends included, I achieved a CAGR of 4.2%. With dividends included, my CAGR increases to 6.8%! This CAGR is computed using the FV() formula in Google Sheets. 

Results are as of 28 Mar 2025. STI has already broken its previous ATH record of 3906 achieved in 2007 before the great recession. 

 I also share an article from Business Times with a statement that probably defied almost all financial influcencers' understanding of the STI:

Noting the index’s new record, SGX said: “Since its inception in 1966, the STI has delivered strong returns to investors, with a total return of 40 per cent over the last three years, (representing a) compound annual growth rate (CAGR) of 11.9 per cent.”

The STI has even surpassed the S&P 500, which has a total return of 31 per cent and a CAGR of 9.4 per cent, the bourse operator noted.

STI beat SP500??? It is not clear what time period is taken for SP500, but I assume it is for last 3 years as stated above. If so, then SGX is cherry-picking the time period to show STI better than SP500. There are many other periods I'm sure where SP500 is better than STI.
