What the score is made of

Each factor is half a curve over reported figures and half a rank among the other Real Estate companies (momentum is judged against fixed thresholds only), and the five are blended by weight. The score is where that blend places it in the S&P 500. It describes the last filing and the current price. It is not a forecast.

EV / EBITDA33.7×

At 67.4× earnings it trades well above the 15× that 5% a year of growth would justify. At 28.0× operating cash flow it trades well above that same mark; for a REIT that counts for more than earnings, since depreciation makes its P/E look worse than the business is.
