Abstract:Financial time series usually exhibit a characteristic known as volatility clustering. In this paper, we analyze open-end funds selectivity and market timing ability under volatility clustering , through adding GARCH(Generalized Auto-Regressive Conditional Heteroskedastic) model to T-M (Treynor and Mazuy) and H-M(Henriksson and Merton) models ,using the weekly returns of 15 open funds established before 2003. Conditioning on timing volatility, we find that traditional T-M and H-M models overestimate the fund managers' selectivity and the systemic risk of portfolio. Therefore, in order to measure more precisely funds performance or the selectivity and timing ability, GARCH effect should be considered.
