-Positively mentioned stocks often performed well before coverage but were already priced in, limiting their impact.
Market Return Predictability:

-Predictive power remained significant even after controlling for external factors (news sentiment, interest rates, liquidity risk).
Opinion
This study provides valuable insights into how financial YouTube content influences investment decisions. The finding that negative sentiment has a stronger impact on investor psychology aligns with behavioral finance theories.
However, since positive sentiment is often priced in before coverage, simply following 3PROTV recommendations may be risky. Additionally, the limited research period makes it difficult to assess the long-term validity of the findings.
Ultimately, while 3PROTV content can serve as a useful reference, investors should be cautious when relying solely on sentiment-based strategies.
Core Sell Point
3PROTV content influences investment decisions, but negative sentiment has a stronger impact, while positive sentiment is often already priced in.
"Information Content of Financial YouTube Channels: A Case Study of 3PROTV and the Korean Stock Market" This study examines the content of 3PROTV, a major Korean financial YouTube channel, and analyzes whether its content provides useful insights for stock selection and market timing.
1. Research Objectives
Determine whether 3PROTV content conveys positive or negative sentiment about specific stocks.
Assess whether 3PROTV content can be used to predict future market returns.
2. Research Methodology
Collected transcripts of 3PROTV’s YouTube content from August 2, 2022, to November 28, 2022.
Identified mentioned stocks using DataGuide’s Korean company name database.
Analyzed sentiment levels using KOSELF (Korean Sentiment Lexicon for Finance).
Used the Fama-French 5-Factor Model to estimate expected returns and calculate abnormal returns.
Developed a sentiment index to assess its predictive power for future market portfolio returns.
Controlled for News Sentiment Index (NSI), short-term interest rates, and liquidity risk factors (PctZero) to validate results.
3. Key Findings
Stock Selection Insights:
Negatively mentioned stocks underperformed after being featured.
Positively mentioned stocks performed well before being featured but were often already priced in, limiting their investment value.
Investors may overreact to overhyped stocks or face higher volatility.
Market Timing Indicator:
Changes in 3PROTV sentiment were effective in predicting market returns.
The 3PROTV sentiment index successfully predicted the direction of market portfolio returns for the following two days.
This predictive power remained significant even after controlling for external factors such as news sentiment, interest rates, and liquidity risk.
This suggests that 3PROTV content can provide valuable market timing insights.
4. Conclusion
This study shows that 3PROTV content is useful not only for selecting individual stocks but also for determining overall market timing. However, these findings are based on a limited sample period (2022), and negative sentiment appears to have a stronger influence on investor behavior than positive sentiment.
