What the numbers say

Simon Property Group scores 57 for management and 73 for moat. The management score rests on a return on invested capital of 8.5% and a gross margin of 85.7% — figures that describe returns closer to the cost of the capital behind them. The balance sheet carries debt at 5.60x equity, which magnifies both the returns above and the risk beneath them. The solid moat and mixed management are not the same judgement, and the gap between them is where the argument about this business sits.

The valuation runs on assumptions chosen to understate rather than flatter. Growth is modelled at 6.7% a year, below the 7.0% actually measured over the last decade — the model caps growth rather than extrapolating a good run forwards. The exit multiple assumed is 13.3x. That produces an intrinsic value of $89.02, a 10-CAP price of $108.50 and a payback time price of $117.37, with the value zone set at the highest of the three, $117.37. Today's price of $200.81 is 71% above it.

The price is above the value zone and the business scores 73 for moat and 57 for management. Neither test argues for paying up here.
