## Full page content

Investor Engagement Depth (IED) measures the breadth, frequency, recency, and significance of investor interactions across channels. It distinguishes investors who are lightly aware of a firm from those who are actively and repeatedly engaged.

 Why it matters

 Not all engagement is equal. IED helps a firm separate investors who occasionally open an email from those consistently attending events, reviewing materials, and initiating conversations, which is essential context for prioritizing investor nurturing effort.

 How to calculate it

 Combine measures of interaction frequency, channel diversity, recency of last engagement, and significance of each interaction into a single depth score, then track that score per investor or cohort over time.

 What good looks like

 In most cases, a higher IED score indicates sustained, multi-channel interest that is more likely to convert. A stronger result may suggest that investor education content and communication cadence are resonating with the audience.

 Common failure mode

 A common failure mode is counting passive actions, such as an email open, with the same weight as active engagement, such as a reply or meeting request, which inflates apparent depth without reflecting real interest.

 Relationship to other measures

 IED is a key Relationship Capital metric describing the intensity of individual relationships. It works alongside Investor Relationship Maturity Score , Investor Education Progression Score , and Relationship Capital Growth Rate .
