Influence and Predictive Value of Seeking Alpha Articles
研究发现Seeking Alpha作者的建议能显著影响交易活动，文章的可读性和表面特征决定了其影响力，而深度分析文章则提供更有价值的长期投资建议。
We find that recommendations issued by Seeking Alpha authors can affect trading activity substantially, which makes them an interesting source of information for retail and professional traders alike. A recommendation’s chances to become influential in this sense are greater for more accessible articles and depend on characteristics that are observable without reading the text. This result is in line with the existence of processing costs, as Seeking Alpha community members might be unwilling to spend much effort reading full articles and instead use superficial criteria to decide which articles to follow. Article features that are consistent with a detailed, in-depth analysis provide more valuable mid- to long-term investment advice. However, the immediate reaction from readers to such articles appears to be less pronounced. We provide evidence for potentially profitable investment strategies based on those article features.
