 Detecting sudden changes in volatility estimated from high, low and closing pricesDilip Kumar and S. Maheswaran Economic Modelling, 2013, vol. 31, issue C, 484-491 Abstract: In this paper, we assess the size and power properties of Inclan and Tiao's (1994) Iterated Cumulative Sum of Squares (IT ICSS) algorithm for detecting sudden changes in volatility. We make use of the variance estimator that utilizes high, low and closing prices proposed by Rogers and Satchell (1991) (RS) and compare it with the performance of the demeaned squared returns. We find that the IT ICSS algorithm exhibits more desirable size and power properties when applied with the RS estimator in comparison to the demeaned squared returns. On the empirical side, we apply the IT ICSS algorithm with the RS estimator and demeaned squared returns of the S&P 500, CAC 40, FTSE 100, IBOVESPA and SZSE Composite indices to detect sudden changes in volatility of both developed and emerging markets. We find that most of the structural breaks detected by the RS estimator can be related to major macroeconomic events while very few of the structural breaks detected by demeaned squared returns can be related to macroeconomic events and hence are probably spurious.
