Building a Better Portfolio: How Financial Science Guides Our Investment Strategy
Mar 6, 2025
At Endeavor Advisors, we believe that a smart, long-term investment approach is built on a solid understanding of how markets work. By applying principles from financial science, we design portfolios that capture the market’s inherent strengths instead of chasing short-term gains. In this post, we break down our investment philosophy into easy-to-understand sections.
Trusting the Market: The Power of Efficiency
The foundation of our strategy is the idea that market prices are generally fair. This belief comes from the efficient market hypothesis, which suggests that stock prices reflect all available information. In practice, this means that trying to outsmart the market through short-term speculation often leads to unnecessary costs and lower returns.
What It Means for You:
A low-cost, index-based approach tends to perform better over the long term.
Rather than attempting to predict market trends, we rely on the market’s natural ability to incorporate new information quickly.
For example, research shows that portfolios built on these principles can significantly outperform a traditional S&P 500 index portfolio over time.
Capturing Market Dimensions: A Three-Factor Approach
Our strategy is also guided by a robust framework that identifies three key drivers of equity returns:
Market Exposure: Stocks typically offer higher returns than fixed-income investments.
Size Factor: Historically, smaller companies have provided higher expected returns compared to larger companies.
Value Factor: Stocks that appear undervalued often outperform their higher-priced, growth-oriented counterparts.
How We Use This Framework:
Strategy Design: We tailor your portfolio to balance exposure across these three dimensions.
Risk Management: By understanding these factors, we can better control risk while aiming for higher returns.

Diversification: Reducing Risk While Enhancing Returns
Investing wisely means understanding the different types of risk:
Systematic Risk: Market-wide risks such as economic downturns or inflation.
Unsystematic Risk: Risks specific to individual companies or industries.
By spreading investments across various asset classes, industries, and regions, diversification minimizes unsystematic risk and helps smooth out portfolio volatility.
Key Benefits:
Reduces the impact of any single investment’s poor performance.
Positions your portfolio to benefit from broad economic trends without exposing you to excessive risk.

Structure: Smart Asset Allocation for Consistent Growth
Asset allocation—the mix of stocks, bonds, real estate, and other assets—is the most critical factor in portfolio performance. Studies have shown that the way you structure your investments is responsible for most of the variation in returns.
At Endeavor Advisors, we take the time to understand your unique risk tolerance and financial goals. This allows us to craft a personalized asset allocation strategy that:
Maximizes expected returns.
Minimizes volatility.
Provides a stable foundation for long-term growth.

A Better Approach to Investing
Our philosophy at Endeavor Advisors is simple: Instead of trying to outsmart the market through speculative trading, we focus on capturing its long-term benefits. We do this by:
Embracing the efficiency of markets.
Leveraging a proven three-factor framework.
Diversifying broadly to reduce risk.
Structuring portfolios with a personalized asset allocation.
As legendary investor Warren Buffet has pointed out, the best way to own common stocks is through low-cost index funds. By combining this insight with financial science, we aim to build portfolios that deliver superior long-term results.
