performance-attribution

Portfolio excess returns are decomposed using Brinson attribution to isolate sector allocation, stock selection, and interaction effects, explaining whether outperformance stems from genuine stock-picking skill or specific sector exposures.

Alpha beta decomposition and market-timing ability are evaluated using Treynor-Mazuy and Henriksson-Merton models, which assess portfolio returns against benchmarks to identify timing contributions and factor exposure.

Yes, you can analyze investment strategies against specific benchmarks like CSI 300 or S&P 500, calculating risk-adjusted performance metrics including Sharpe, Sortino, and Information Ratio to evaluate excess returns.

Risk-adjusted performance metrics like Sharpe, Sortino, and Information Ratio are calculated by comparing portfolio volatility and downside risk against benchmark returns to quantify the efficiency of the investment strategy.

Portfolio outperformance is diagnosed by decomposing returns to determine if alpha originates from genuine stock-picking skill or unintended exposure to small-cap and momentum factors, clarifying the actual sources of excess returns.
