Private equity accounts for 22% of the average family office portfolio worldwide and interest is rocketing among families, a new study by Campden Research says. The new Private Equity Investing and Co-Investment Activity by Family Offices report, released today, said interest in the asset class in the family office community continued to grow, driven mainly by outsized returns and the availability of opportunities “that are deemed superior to those within public equities”. The report, in partnership with global investment firm KKR, analyses why key trends within the private equity and co-investing arena have occurred.
