How many institutions own NEO?
InsiderSet currently tracks 270 institutional managers reporting NEO holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of NEO shareholders.
