  • Ans. 

    To quantify if an OLS is the best fit, one can use metrics like R-squared, adjusted R-squared, AIC, BIC, and F-statistic.

    • Calculate the R-squared value - a higher R-squared indicates a better fit

    • Calculate the adjusted R-squared value - it penalizes for adding unnecessary variables

    • Check the AIC and BIC values - lower values indicate a better fit

    • Analyze the F-statistic - a significant F-statistic suggests the model is a g

  • Q6. Is duration adjustment always +ve or -ve
  • Ans. 

    Duration adjustment can be positive or negative depending on the direction of interest rate movement.

    • Duration adjustment is positive when interest rates decrease, leading to an increase in bond prices.

    • Duration adjustment is negative when interest rates increase, resulting in a decrease in bond prices.

    • Investors use duration adjustment to hedge against interest rate risk in their portfolios.
