The number I should have watched from day one on my first mREIT
I put $5,000 into an agency mortgage REIT 15 months ago because the yield line said 11 percent and I wanted to see how one of these actually behaves before I put real money anywhere. 806 shares at $6.20.
What happened: the quarterly dividend held at $0.17 the whole time, so $548 in cash across four payments. The share price went from $6.20 to $5.95, so I was down $202 on price. Sold nothing, but if I mark it today I'm up roughly $346 on $5,000. About 7 percent over 15 months, all of it from the dividend and none of it from the price.
The part that nearly broke it was month four. Price dropped to $5.30 and I was sitting there at 11pm ready to sell. What stopped me was that I'd finally started reading the quarterly book value per share instead of just the price. Book value had gone from $7.05 to about $6.90. The company hadn't lost 15 percent of anything, the market had just widened the discount it was willing to pay. When I understood that, the price move stopped feeling like information about the business.
Book value per share is the company's assets minus its debt, divided by shares outstanding. For a mortgage REIT it's mostly the marked value of the mortgage bonds they hold minus what they borrowed to buy them. It moves with rates. It is the closest thing to a scoreboard these things have.
What I'd keep: check book value every quarter, ignore the price between checks, and size it so the dividend isn't paying for anything I need. What I'd change: I'd have written down before buying what a dividend cut would do to my thinking, because I hadn't, and I only found out in month four that I had no plan.
