How StockRisker Works
StockRisker evaluates portfolio risk and performs portfolio optimization by analyzing historical volatility and correlations between your holdings. The system builds risk-based portfolios that balance expected return with volatility, ensuring appropriate diversification across sectors and assets. This approach helps you understand how your investments interact together and optimize portfolio allocation to match your risk tolerance.
Why Understanding Portfolio Risk Matters
Understanding portfolio risk helps investors build more stable and effective allocations. Measuring risk reveals how your investments behave together, highlighting concentration and correlation issues that individual stock analysis misses. This knowledge supports better diversification decisions, helping you create portfolios that match your risk tolerance and long-term goals while maintaining stability through market volatility.
