Swensen's 20% in REITs Is Too Much for Me

A reader left a question asking how much to allocate to REITs in a portfolio. He noted David Swensen's 20% suggestion and wondered if that number is too high. The reader also asked about foreign REIT exposure.

To me this is like asking how much to put in commodities. For either question, there is no shortage of smart people and well-written white papers suggesting big numbers to these asset classes.

To be clear, I am not going to out-debate anyone on this point, and anytime I write this sort of post, someone will leave an articulate comment saying why a diversified portfolio should have more exposure than the sorts of numbers I kick around.

If you think about the various asset classes available that help bring a portfolio away from looking like an index fund, you could quickly get to owning nothing but the diversifiers (small hyperbole). There are REITs, commodities, infrastructure, a call writing something or other, absolute return and you might have a couple to add to the list that I'm missing.

Swensen says 20% to REITs. There are some that would say 20% to commodities, and I imagine the other segments I mentioned each have fans that would argue 10%. If you pull in all those disparate opinions, you'd be 70% in diversifiers and 30% equities. I doubt too many people think that would be a good idea.

One thing that needs to be incorporated into the thought process is that stocks have been the best performing asset class over long periods of time (we've all seen that Ibbotson's chart). The various diversifiers, from where I sit, are for smoothing out some of the volatility that goes with owning equities. They are not intended to be substitutes.

Additionally, every so often something goes wrong with these sorts of things. Over the last 12 months iShares REIT (IYR) is down more than the Financial Sector SPDR (XLF). Long time readers will know I only had one across the board REIT name at a 2-3% weight, that it did poorly and that I sold it in December and have not replaced it. That one stock, at 2-3%, was it for several years. I generally believe REITs offer diversification benefits, but of all of the niche things in my ownership universe, my comfort level with REITs has never been that high.

For some of themes I would consider two holdings at 2-3% each, but can't see it for REITs. As far as foreign goes, the Hong Kong markets gets written about like it is the healthiest market out there. However I just read something somewhere that said because of HKD's peg to the greenback, rates in HK were lowered, but their inflation rates make the cuts a bad idea and mortgages there are much cheaper than they should be, so this creates visibility for a problem. I have no idea if there will be a problem, but the path to one is easy to see.

While I am acutely aware that I am no David Swensen, 20% in REITs is way too much for me. The number I had been using might be too low most of the time, but I was lucky during the selloff of the last few months.

Here are three I have been using. It has been a little bumpy. IGR, MPW and FSP. I am no where near 20%, I have about 2% in each.

What is your opionion of WPS? WPS is in its lower range. Do you see WPS gaining in the forthcoming days? Is international real-estate moving better than domestic?

a lot of what I read says that the RE crisis is just now getting to Oz, Spain, Ireland, UK etc. does that effect an Aussie mall operator with half its properties in the US? do you want 20% in Japan RE? The HKD peg does some strange things to HK RE and interest rates what do you know about that?

I've got some questions for you but not too many answers. Is your interest because it is down from where it was or because looking forward you can build a case for it going higher?
