I've always felt uneasy about investment strategies like this - an intellectually dishonest investor can simply define a REIT sponsor as a good one if the REIT has performed well historically, otherwise the REIT sponsor cannot possibly be a good one. This is tautological reasoning and useless to serious investors.
So yesterday, I went back to the library during my break to get this out of my chest once and for all.
For the purposes of the rest of the experiment, my baseline is an equal weighted portfolio of Singapore REITs. Buying this and rebalancing every year would have resulted in 10.51% annual returns. The downside risk or semi-variance is a modest 13.09%. Experiment was performed 14 Dec 2018.
I made a decision that my proxy for "good" REIT sponsor is larger market capitalisation. I admit that this may not be the best way to conduct the experiment because my backtesting tools do not have a filter for sponsor.
So bear with me for this, for I have reason to believe that my proxy be valid.
Suppose you filter out the top 10 REITs in terms of market capitalisation would get a list that looks like this:
I can only convince you that the list of largest ten REITs should generally have what most retail investors would subjectively consider as "good" sponsors. They do seem to have more prestigious names.
But let us also look instead at the smallest ten REITs :
This list very likely contains REITS that have sponsors which may be less prestigious ( at least based on the subjective opinions of most retail investors ).
So, I backtested two strategies : The first strategy invests in the top 10 largest REITS on SGX for 12 years rebalancing every year. The second strategy invests in the top 10 smallest REITS on SGX for 12 years rebalancing every year.
Investing in the largest ten REITS would result in superior returns compared to the baseline. Returns are 11.42% and a semi-variance of 14.30%. Perhaps a smaller subset of stocks resulted in a higher volatility. This modestly superior performance may be the reason why so many people believe that a superior strategy can be had by picking superior sponsors.
But investing in the smallest ten REITs also resulted in superior performance. In fact it was tad higher than the first strategy at 11.43%. The counter-intuitive result comes from a lower downside risk - semi-variance was 12.77%. Investing in smaller REITs would have resulted in higher returns and lower downside risk compared to buying all REITs in the stock market.
I think these results cast doubt on the hypothesis that investors should choose "better" REIT sponsors.
Instead I propose the following hypothesis about the REITs market in Singapore - most investors gravitate towards REITs with better sponsors so much so that they become more expensive, resulting in performance that is actually sub par compared to REITs with sponsor who are less prestigious.
Investors who actually follow the crowd and pick the "better-run" REITs are not just handicapped based on returns, they end up with a more volatile portfolio.
As always I am open-minded to any counter-arguments because I am constantly second guessing my own approach towards investing in REITs.
Let me know what you think.
