股票价格变化是股票市场上参与各方最为关注的焦点,也是相关利益者研究的重点。移动平均线是预测股价趋势的技术分析方法。通过研究发现,在中国市场上持有期可变移动平均规则(VMA)中的短期均线具有最强的预测力,中期均线这种预测力略减,到了长期均线时预测力已经很差。国外市场无论是规律性还是程度都明显弱于中国股市。采用移动平均线交易策略可以获得比买入——持有策略较高的收益率,为倡导理性投资提供了有力的证明。  相似文献

本文采用程序交易的方法检验了1990年12月至2008年6月上证指数各交易日收盘指数据,检验结果表明, 指数-10日均线交叉的交易规则能够超越买入并持有策略.具体表现为,该交易规则收益率的均值高于市场的收益率均值,收益率的标准差低于市场收益率的标准差.指数-10日均线交叉的交易规则对时间变动、交易成本变动和样本变动具有很好的稳健性. 指数-10日均线交叉的交易规则主要特点是能够有效地避免市场的大幅度下跌.  相似文献

本文以我国融资融券试点启动为背景,对融资融券可能引发的负面效应——内幕交易行为进行了检验。研究发现,融资融券启动后标的公司中发生内幕交易的可能性显著上升,且这种现象在规模较小、机构持股比例较高的公司中更加明显,而较好的外部法治环境能够约束上述行为,在法治水平较高的地区,融资融券对内幕交易的刺激效果减弱。研究结果表明,融资融券业务开展助长了内幕交易者的套利行为,但有效的法治治理能够起到一定的遏制作用。  相似文献

We ask what determines the profitability of candlestick trading strategies. Is it the definition of trend and/or the holding strategy that one uses in candlestick charting analysis? To answer this, we systematically consider three definitions of trend and four holding strategies. Applying candlestick trading strategies to the DJIA component data, we find that regardless of which definition of trend is used, eight three-day reversal patterns with a Caginalp–Laurent holding strategy are profitable when we set the transaction cost at 0.5% and after we account for data-snooping bias, while the patterns with a Marshall–Young–Rose holding strategy are not profitable. For sensitivity analysis, we also find that our results are not qualitatively changed on a lower transaction cost of 0.1%, or when we conduct the subsample analyses based on three equal periods and three distinct market conditions. When considering a more volatile market, evidence in favor of candlestick trading strategies is strengthened.  相似文献

Abstract

In recent years, the validity of the weak form efficient market hypothesis (EMH) has been called into question as several studies have uncovered evidence that technical trading rules have predictive ability with respect to both developed and emerging stock market indices. This study analyses the forecasting power of 2 of the most popular trading rules using index data for a selection of 11 European stock markets over the January 1991 to December 2000 period. The findings indicate that the emerging markets included in this paper are informationally inefficient; these markets displayed some degree of predictability in their share returns, although the developed markets did not. Furthermore, the results point to large differences in the performance of the rules examined; while small size filters consistently outperformed the buy-and-hold strategy in the emerging markets examined even after the consideration of transaction costs, the performance of the moving average rules was erratic and varied dramatically from market to market.  相似文献

This study examines the potential profit of ten Variable Length Moving Average (VMA) technical trading rules in ten emerging equity markets in Latin America and Asia from January 1982 through April 1995. The average difference in buysell returns after trading costs for each rule and country are compared to a buy and hold strategy. Taiwan, Thailand and Mexico emerge as markets where technical trading strategies may be profitable. We find no strong evidence of profitability for the other markets. However, we find that 82 out of the 100 country–trading rule combinations tested in ten emerging markets, disregarding their statistical significance, correctly predict the direction of changes in the return series. These findings may provide investors with important asset allocation information.  相似文献

We examine causality and efficiency in the Italian T-bond market, where cash trades take place on the domestic Mercato Telematico dei Titoli di Stato, while futures trading is based on the London International Financial Futures Exchange. We find evidence that causality in prices runs in both directions, and that the cash lead is almost comparable in size and extension to the futures lead. We then try to assess whether the cash market is weak-form efficient with respect to LIFFE prices. Using a simple trading rule with a variety of time and price filters, we conclude that the observed lead cannot be exploited to make a profit after transaction costs.  相似文献

Technical analysis (TA) is used in evaluating its predictive power for the Morgan Stanley Capital International (MSCI) Emerging Market Index (EMI) that reflects 23 emerging market economies’ equity indices. We conclude strong predictive power of technical analysis for the EMI. Given this predictive power of TA, we then investigate whether investors can exploit this predictive power to beat the profitability of the Buy‐and‐Hold strategy considering both risk and transaction costs. Applying Moving Average, Relative Strength Index, Moving Average Convergence Divergence, and Rate of Change trading rules to the MSCI Emerging Market Index over the period of 11/1/1988 to 5/1/2017 reveals strong empirical evidence that investors could use TA to out‐perform the Buy‐and‐Hold strategy even when considering risk and transaction costs. This research provides evidence against the Efficient Market Hypothesis for EMI.  相似文献
