Institutional investors held onto stocks longer after the 2008 financial crisis, according to a report by Abel Noser Solutions.
The company studied historical trading records for 30 institutional investors and found that the average annual turnover -- how often stocks are replaced with new holdings -- declined significantly after the fourth quarter of 2008.
The quarterly average annualized turnover rate peaked at 206.8% in Q3 2008, falling as low as 107.4% in the fourth quarter of 2013.
While the overall turnover rate has ticked up in recent quarters, ANS said large managers continue to see their ratios drop; the average turnover ratio for large managers in Q1 2015 was 60%.
