英语隐含条件句及其翻译

通常，条件是结果产生的依据，二者相互依存。但在话语表达中有时却只有结果而隐去了条件。条件隐含在言语片段中，需要经过逻辑分析才能找出来．本文把这种条件称为隐含条件，并把含有这类隐含条件的句子称为隐含条件句。本文将主要参照许凤娇著《英语隐含条件句剖析》和张培基等人著《英汉翻译教程》对英语隐含条件句做较为详细的分类和翻译技巧介绍．     

永远的狂人,独立的自己——鲁迅小说《狂人日记》和《头发的故事》比较研究

1920年鲁迅小说《头发的故事》发表,《头发的故事》和早期的《狂人日记》在叙事层面存在惊人的相似性:除去不同的隐指读者,两者的叙事层次、人物功能和干预评论等均一脉相承。小说形式的"同"与"异"最终透露了作家的思想观念在不同时期的一致性和嬗变性,这对于理清现代文学史上纷繁复杂的鲁迅思想脉络具有重要作用。     

无模型隐含波动率及其所包含的信息: 基于恒生指数期权的经验分析

对香港恒生指数期权所含信息进行研究,并通过使用无模型隐含波动率对期权市场的效率进行直接检验, 结果发现:无模型隐含波动率所含信息最多, 它完全包含了所有历史波动率 所含信息,香港恒指期权市场是有效的; 在对未来一个月的预测中,无模型隐含波动率还完全包含了~BS~隐含波动率的信息, 在对未来两个月的预测中, 无模型隐含波动率虽不能完全包含~BS~隐含波动率,但仍然包含了最多的信息; 期权市场交易量的大小, 同时交易的不同行权价的期权的多少, 是影响无模型隐含波动率预测能力的重要因素;为追求积分密度进行过多人为的插值以及过大区间的积分,会导致无模型隐含波动率预测能力的降低,由此得到了无模型隐含波动率的相对合适的计算方式.美国已于~2003~年开始采用 无模型隐含波动率编制波动率指数.随着金融衍生品市场的不断发展,无模型隐含波动率在资产定价、风险管理方面将发挥越来越重要的作用.

The Information Content of Intraday Implied Volatility for Volatility Forecasting

This study examines the intraday S&P 500 implied volatility index (VIX) to determine when the index contains the most information for volatility forecasting. The findings indicate that, in general, VIX levels around noon are most informative for predicting realized volatility. We posit that the VIX performs better during this time period because trading motivation around noon is less complex, and therefore trades contain more information on the market expectation of future volatility. Further investigation on the 2008 financial crisis period suggests that market participants become more cautious, and thus the forecasting performance is sustained until the market's close.

The Forecasting Efficacy of Risk‐Neutral Moments for Crude Oil Volatility

This paper examines the information content of implied volatility for crude oil options as it relates to future realized volatility. Using data for the period 1996 to 2011 we find that implied volatility is an effective predictor of the month‐ahead realized volatility. We show that implied volatility subsumes the information content of contemporaneous volatility, and it contains incremental information on future volatility after controlling for contemporaneous volatility. Furthermore, incorporating risk‐neutral skewness, and especially kurtosis, improves the forecasting of realized volatility. Overall, the association between implied volatility and month‐ahead realized volatility is consistent with evidence documented for other asset classes, leading us to conclude that implied volatility serves as a reasonable proxy for expected volatility.

The Realised–Implied Volatility Relationship: Recent Empirical Evidence from FTSE‐100 Stocks

This paper examines the long‐run relationship between implied and realised volatility for a sample of 16 FTSE‐100 stocks. We find strong evidence of long‐memory, fractional integration in equity volatility and show that this long‐memory characteristic is not an outcome of structural breaks experienced during the sample period. Fractional cointegration between the implied and realised volatility is shown using recently developed rank cointegration tests by Robinson and Yajima (2002). The predictive ability of individual equity options is also examined and composite implied volatility estimates are shown to contain information on future idiosyncratic or stock‐specific risk that is not captured using popular statistical approaches. Implied volatilities on individual UK equities are thus closely related to realised volatility and are an effective forecasting method particularly over medium forecasting horizons.
