预测金融市场与谷歌趋势和不那么随机的关键字

Predicting financial markets with Google Trends and not so random keywords

Damien Challet, Ahmed Bel Hadj Ayed

摘要:

我们检查了Google趋势数据包含足够数据来预测未来金融指数回报的说法。我们首先讨论许多微妙的(和不那么微妙的)偏见,可能会影响回测的交易策略,特别是当基于这样的数据。不出所料,关键词的选择是至关重要的:通过使用行业级的回测系统,我们验证了随机金融相关的关键词不包含更多的可利用的预测信息比随机关键词相关的疾病,老爷车和街机游戏。然而,我们发现,在合适的资产上应用其他关键词会产生稳健的盈利策略,从而证实了Preis等人的直觉。

英文摘要:

We check the claims that data from Google Trends contain enough data to predict future financial index returns. We first discuss the many subtle (and less subtle) biases that may affect the backtest of a trading strategy, particularly when based on such data. Expectedly, the choice of keywords is crucial: by using an industry-grade backtesting system, we verify that random finance-related keywords do not to contain more exploitable predictive information than random keywords related to illnesses, classic cars and arcade games. We however show that other keywords applied on suitable assets yield robustly profitable strategies, thereby confirming the intuition of Preis et al. (2013)
