About ModernIR

Based in Denver, CO, and launched in January 2005, ModernIR has been helping public companies understand their trading activity by bringing sophisticated database systems and deep investor relations experience to the discipline of trading intelligence. ModernIR is the No.1 Market Structure Analytics™ firm in the IR profession, serving a rapidly growing client base in excess of $1.5 trillion in market capitalization.

Our Philosophy

If the investor relations role is to be relevant, accurately informed, and seated at the management table today, a grasp of market structure should be a core competency. Otherwise, it’s a certainty that conclusions about stock movement and market health will be incomplete or inaccurate, and that effort will be wasted on outreach and targeting when market structure is working against it. We strive to level the playing field between corporate investor relations and the new algorithmic order in modern equity markets.

Our Guarantee

We synthesize vast amounts of data into simple, clear views. So armed, investor relations officers can give accurate answers about stock performance, prioritize strategic and tactical IR programs, and measure the results of capital markets communication. Plus, we back a promise of great service with a litmus test: No long-term contracts. Either we consistently serve as a valuable ally helping you get the most from your IR efforts, or we don’t continue to earn your business.
