These companies operate in different sectors (AD (Communication Services) and CCOI (Communication Services) and LUMN (Communication Services) and IIPR (Real Estate)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: AD is a small-cap deep-value stock; CCOI is a small-cap income-oriented stock; LUMN is a small-cap quality compounder stock; IIPR is a small-cap deep-value stock. AD, CCOI, IIPR pay a dividend while LUMN does not, making them suitable for different income and tax situations.
