For decades, the world of financial advisors has been dominated by largeinvestment banks such as Goldman Sachs. In recent years, user-contributedinvestment services such as SeekingAlpha and StockTwits have grown to millionsof users. In this paper, we seek to understand the quality and impact ofcontent on social investment platforms, by empirically analyzing completedatasets of SeekingAlpha articles (9 years) and StockTwits messages (4 years).We develop sentiment analysis tools and correlate contributed content to thehistorical performance of relevant stocks. While SeekingAlpha articles andStockTwits messages provide minimal correlation to stock performance inaggregate, a subset of authors contribute more valuable (predictive) content.We show that these authors can be identified via both empirical methods or byuser interactions, and investments using their analysis significantlyoutperform broader markets. Finally, we conduct a user survey that sheds lighton users views of SeekingAlpha content and stock manipulation.
