Across its top 20 institutional holders, IEO's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 8/100, avg. turnover score 26/100).
IEO ranks #3496 out of 37503 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
