Abstract:This paper presents a new Cumulative Sum approach for the detection of turning points in financial time series that are subject to cyclical mean level and volatility regime shifts. The new CUSUM approach is applied to the problem of detecting turning points in ldquohot issuerdquo markets for Initial Public Offerings (IPOs), thus providing a multi-dimensional characterization of states of the IPO cycle.
Keywords:CUSUM approach  IPO cycle  turning points
