Seems Buffett, not Munger, first offered that quote. They both may have used it a few times over the years. I always look to see how stocks performed in the low tide years of 2008 and 2000.
I think I've been kicking tires for an REIT for 15 years. DLR certainly has performed well over the years. Yield is very small for a REIT that pays out almost all income.
