Bootstrapping and Inflation Hedging Performance of Korean Equity Funds

This paper examines the inflation hedging performance separated into expected and unexpected inflation in Korean equity funds. In particular, using the bootstrap approach, we identify whether the inflation hedging performance is based on skill or luck. We use the equity funds of the average net asset value (NAV) over 5 billion Korean won and over the 80% stock position. The sample data cover the period from January 2002 to March 2015. The main findings are as follows. First, most equity funds demonstrate a hedging performance against the unexpected inflation shock and this hedging performance seems to come from the fund manager’s skill. Second, our findings are robust across the sieve bootstrap results for the serial dependence and heteroscedasticity. Third, the equity funds have slightly different inflation hedging performances depending on their investment style. Among the investment styles, small-cap, growth, or small and growth style funds demonstrate more hedging performance against unexpected inflation shock. This hedging performance seems to come from the fund manager’s skill. Finally, in the case of the funds separated by winner and loser, the winner funds have more hedging performance for unexpected inflation shock than the loser funds.
