The findings, led by assistant accounting professor Austin Moss along with co-author Betty Liu, offer insight into the tactics of fake news platforms and their impact on the stock market.
The Rise of False Financial News
In the years following the 2016 U.S. election, fake financial news has surged, particularly in the aftermath of the start of the 2020s. This period is marked by heightened rates of fake news reports, as investors often rush to react to information before others, leading to a cascade of negative stock price movements.

For instance, the real estate company Farmland Partners experienced a stock price drop over 40% in just one day due to a fabricated earnings report claiming a 310% increase, demonstrating how a single false claim can cause significant financial impact.
Why investors fall for fake news
Key factors contribute to the effectiveness of fake news manipulations.

The study found that 57% of fake articles in seeking alpha discussions accounting-related topics, while genuine articles referenced accounting with 88% involvement. This suggests that while manipulation is primarily information-based, genuine data remains a crucial component of accountability.

These tools capitalize on sensational headlines and clicks, despite the lack of genuine, verifiable data. Some authors even use the lens of popularity for manipulative purposes, leveraging social media and sentiment analysis for their own benefit.

This high activity level creates a 百 junkyard容易避免在真实市场中释放的信息环境下更容易被利用。In a study of 125,475 crowdsourced financial articles, fake news authors reported topics related to accounting more frequently than genuine articles. This discrepancy highlights the increasing potential for manipulation in fast-paced markets.
