"The Wikipedia Effect: Analyzing Investor Attention for Strategic Investment Decisions"
This paper analyzes investment strategies in the stock market using Wikipedia page view trends as a measure of investor attention. Inspired by previous studies that used Twitter activity and Google search volumes as proxies for investor interest, this research empirically examines whether Wikipedia page views reflect investor attention and, in turn, influence actual investment performance.
Wikipedia Page Views and Investor Attention
Wikipedia is a freely accessible online encyclopedia where users can search and edit information. An increase in Wikipedia page views for a specific company or stock indicates heightened search activity and interest in that entity. This increased activity may be triggered by:
New Information: Investors may seek more details on a company following major announcements, such as product launches, earnings reports, or M&A activities.
News Coverage: When a company receives significant media attention, investors might turn to Wikipedia for additional background information.
Social Media Influence: Mentions of a company on social media can drive investors to Wikipedia for further insights.
Rising Interest: As a stock gains popularity, more investors may research it using Wikipedia.
Retail Investor Influx: New retail investors often rely on Wikipedia as an initial source of information before making investment decisions.
The Relationship Between Wikipedia Page Views and Investor Interest
Since Wikipedia page views reflect information-seeking behavior, they can serve as a valuable proxy for measuring investor attention.
Reducing Information Asymmetry: Wikipedia provides accessible corporate information, which is particularly beneficial for retail investors.
Influencing Decision-Making: Investors may base their buy/sell decisions on information obtained from Wikipedia.
Crowdsourced Intelligence: Wikipedia is a product of collective intelligence, offering a balanced and objective overview of companies.
Feedback Loop Effect: Increased Wikipedia traffic can trigger further investor interest, potentially driving stock prices higher.
Thus, a rise in Wikipedia page views signals growing investor interest, making it a useful indicator for identifying investment opportunities. However, it should be considered alongside other factors in a comprehensive analysis.
The Relationship Between Wikipedia Page Views and Stock Returns
Why do companies with rising Wikipedia page views tend to deliver higher stock returns? The underlying mechanisms include:
1) Increased Interest → Higher Demand → Stock Price Increase
Greater investor interest typically translates to increased buying activity, pushing stock prices upward.
2) Positive Sentiment → Improved Market Perception → Stock Price Increase
The dissemination of positive information on Wikipedia can enhance investor sentiment, boosting buying momentum.
3) New Investor Entry → Higher Trading Volume → Stock Price Volatility & Growth
More investors entering the market after researching stocks via Wikipedia can drive trading volume and amplify price movements.
Lower EPS, Higher P/E Ratios
Companies with high Wikipedia page views generally exhibit lower earnings per share (EPS) and higher price-to-earnings (P/E) ratios, which can be attributed to:
Growth-Oriented Investments: Investors prioritize future growth potential over current earnings, assigning higher valuations to companies with strong potential.
Reinvestment Strategies: High-growth firms often reinvest profits into R&D and capital expenditures rather than paying dividends, leading to lower EPS.
Market Expectations: High Wikipedia page views indicate increased investor expectations, sustaining higher P/E ratios.
Investment Strategy: Wikipedia Page Views as a Trading Signal
A long-short investment strategy based on Wikipedia page view trends has demonstrated superior performance over the market benchmark. Specifically, a high-minus-low (H-M-L) portfolio—comparing stocks with high Wikipedia traffic against those with low traffic—produced statistically significant alpha that cannot be explained by traditional risk factors.
Conclusion
Changes in Wikipedia page views can serve as a valuable predictor of stock performance. Investors can use this metric to diversify portfolios and potentially achieve higher returns.
