تاریخچه قیمت سهام و کارایی بازار شاخص سهام عمومی مادرید

We apply Moving Average (MA), Relative Strength Indicator (RSI), Moving Average Convergence Divergence (MACD), and trading breakout (TBO) techniques to investigate the weak-form market efficiency of the Madrid General Stock Index, Índice General de la Bolsa de Madrid (IGBM), from 1/2/1975 to 12/31/2012. The empirical results not only strongly validate the predictive power of trading rules with robust statistical significance in all three sub-periods over the thirty-eight years, but also provide the possible strategies to outperform the buy-and-hold strategy with the consideration of transaction costs and risk. This supports the argument against weak-form market efficiency of the IGBM.
