When making investment decisions, focusing on company fundamentals is essential for long-term success. Key fundamentals like revenue, earnings, debt level and book value reflect a company’s intrinsic value and future earnings potential. By analyzing fundamentals, investors can determine if a stock is undervalued or overvalued. This article summarizes key conclusions on using fundamentals for stock picking, portfolio construction and investment strategy.

simple valuation metrics based on fundamentals can lead to solid returns
As Warren Buffett’s farm and real estate investments demonstrate, even simple valuation metrics based on fundamentals like capitalization rate and earnings yield can result in satisfactory long-term returns, without needing sophisticated analysis. The key is focusing on productive value of assets rather than short-term price fluctuations.
predicting future fundamentals boosts performance of factor models
Research shows that using future fundamentals in valuation models significantly boosts returns. Machine learning techniques can help predict future fundamentals based on historical time series. Portfolios built with predicted fundamentals have higher returns and Sharpe ratios versus conventional factor models.
macro forecasts are unnecessary for long-term fundamental investors
Attempting to predict macroeconomic conditions or market movements is an unproductive distraction for long-term, fundamentals-focused investors. By concentrating on productive assets selling at a discount and ignoring short-term price changes, fundamental investors can achieve solid returns over time.
focus on business value, not speculative price changes
Fundamental analysis aims to estimate intrinsic business value, while speculators try predicting short-term price changes based on factors like momentum and sentiment. Long-term returns accrue to investors focused on value, not speculators focused on prices and technical factors.
simplicity and discipline are key for successful fundamental investing
Adopting a simple, disciplined approach of buying productive assets at a discount to conservatively estimated intrinsic value is the formula for successful fundamental investing. Having the discipline to ignore short-term price fluctuations and macro forecasts is equally important.
By focusing on productive value and future earnings power reflected in company fundamentals, and ignoring short-term price changes, fundamental investors can achieve solid long-term returns. Future fundamentals can be estimated using quantitative models, further improving results.
