RT Journal Article SR Electronic T1 Comparing Changes in Stockholdings of Different Institutional Investors JF The Journal of Investing FD Institutional Investor Journals SP 46 OP 50 DO 10.3905/joi.1999.319388 VO 8 IS 1 A1 Li Li Eng YR 1999 UL https://pm-research.com/content/8/1/46.abstract AB This paper examines differences in the changes in stockholdings of five groups of institutional investors: banks, insurance companies, investment companies, investment advisors, and “other” institutions (consisting of colleges and universities, private foundations, and private and public pensions). Other institutions have the fewest quarterly changes in holdings, followed by banks, insurance companies, investment companies, and investment advisors. There are significant differences in the length of time that institutional investors hold their portfolios (their investment horizons). These results are one input into understanding the impact of institutional investors' time horizons on managerial decision-making.
