Our Methods
-
Quantitative Analysis
Quantitative analysis is a data-driven approach that uses mathematical and statistical models to evaluate investment opportunities. At Sigma 3, we leverage quantitative analysis to assess the financial health of companies, examining factors like earnings growth, cash flow stability, and price-to-earnings ratios. Our analysis also includes complex modeling techniques such as the Capital Asset Pricing Model (CAPM) and Dividend Discount Models to calculate intrinsic values and potential returns. By focusing on these quantitative metrics, we aim to remove emotion from decision-making, prioritizing investments with solid fundamentals and growth potential. This methodology enables us to maintain a disciplined, objective approach to portfolio construction, helping clients achieve consistent returns over time.
-
Asset Allocation
Asset allocation is the strategic division of investments across various asset classes—stocks, bonds, real estate, and other alternatives—to achieve a balanced risk-reward profile. Our approach to asset allocation is centered on diversification, helping reduce portfolio volatility by spreading investments across market-leading sectors and industries. We carefully tailor allocations to each client’s goals, risk tolerance, and time horizon, adjusting as needed to align with changing market conditions. Through this customized allocation strategy, Sigma 3 seeks to optimize growth potential while minimizing downside risk, ensuring that portfolios remain resilient in both bullish and bearish markets
-
Technical Analysis
Technical analysis focuses on studying historical price movements and trading volumes to identify trends and patterns that can indicate future market behavior. At Sigma 3, we use a combination of charting techniques, indicators, and trend analysis to make informed short-term investment decisions. This approach allows us to detect market entry and exit points, enabling agile responses to changing market dynamics. By incorporating technical analysis into our overall strategy, we provide a comprehensive view of market sentiment and momentum, which complements our long-term investment approach and enhances our ability to capitalize on market fluctuations.
