Detailed Analysis of the Data and Its Usefulness
for Registered Investment Advisors (RIAs)
1-8-2025
The provided study examines the Price Risk Indicator (PRI™), a quantitative risk rating system applied to 456,000 individual stock ratings of the 1,500 largest companies over 25 years. The study analyzes 2-year performance and breaks down results by risk categories (A+ to F) with metrics like average 2-year return, probability of gains, and loss magnitudes. Below is a comprehensive analysis:
Key Insights
1) Performance by PRI™ Rating
- “A+” Rating (Lowest Risk):
- Average 6-Month Return: 17.7%.
- Probability of 6-Month Gain: 65%.
- Avg 6-Month Gain: 40.9%; Avg 6-Month Loss: -25.0%.
- Outperformed all other ratings by a substantial margin.
- “F” Rating (Highest Risk):
- Average 6-Month Return: -1.1%.
- Probability of 6-Month Gain: 47%.
- Avg 6-Month Loss: -30.9%.
- Represents stocks with the highest likelihood of poor performance.
2) Overall Trends
- Lower-risk ratings (“A+” and “A”) consistently provide the highest returns and lowest probabilities of loss.
- Higher-risk ratings (“E” and “F”) show significantly negative average returns, reinforcing the reliability of PRI™ in categorizing risk.
3) Yearly Observations
- Some years (e.g., 2003, 2009, 2020) exhibit exceptionally high returns for “A+” ratings (36.0%, 59.9%, 42.2%), often following market downturns.
- Conversely, years like 2007 and 2019 show significant losses even for “A+” ratings (-18.5%, -15.0%), reflecting broader market volatility.
4) Cumulative Results
- Across 25 years, “A+” ratings delivered an average 6-month return of 17.7%, compared to 4.9% for “D” and -1.1% for “F”.
- The probability of gain diminishes from 65% for “A+” to 47% for “F”.
Usefulness for RIAs
1) Identifying Low-Risk, High-Reward Stocks
- Value: The PRI™ system highlights stocks with the lowest risk (“A+” and “A”), enabling RIAs to construct portfolios with consistently high returns and reduced risk exposure.
- Actionable Insight: Focus on stocks with “A+” and “A” ratings for conservative clients seeking reliable growth.
2) Avoiding High-Risk Investments
- Value: By categorizing “F” ratings as the highest risk, the system provides clear guidance on stocks to avoid, minimizing portfolio drawdowns.
- Actionable Insight: Steer clear of “E” and “F” ratings for clients with low risk tolerance, particularly during volatile markets.
3) Risk-Adjusted Portfolio Construction
- Value: The PRI™ data allows RIAs to balance portfolios by incorporating both high-return, low-risk stocks and moderate-risk opportunities based on client preferences.
- Actionable Insight: For clients with moderate risk tolerance, blend “B” and “C” rated stocks for diversified returns.
4) Historical Context for Decision-Making
- Value: The 25-year dataset equips RIAs with historical performance trends, enabling them to backtest strategies and validate risk assumptions.
- Actionable Insight: Use historical data to justify investment decisions and communicate the expected outcomes to clients.
5) Timing Market Opportunities
- Value: The PRI™ system reveals patterns in market cycles, such as high returns in recovery years (e.g., 2009, 2020). RIAs can use this insight to optimize entry points.
- Actionable Insight: Focus on high-rated stocks (“A+” and “A”) during economic recoveries for maximum gains.
