A manager's portfolio has monthly active returns with a standard deviation of 0.75%. Assuming independent monthly active returns, what is the annualised tracking error?

Annualised tracking error scales monthly active risk by the square root of 12 under independence. 0.75% times 3.464 is about 2.60%. Multiplying by 12 would wrongly assume perfectly correlated monthly active returns and overstate the risk at 9%.

  1. A9.00%
  2. B2.60%Correct
  3. C0.75%
  4. D6.50%

Explanation

Annualised tracking error = 0.75% x sqrt(12) = 0.75% x 3.464 = 2.598%, about 2.60%. 9.00% multiplies by 12 instead of the square root. 6.50% is a miscalculation using sqrt(75). 0.75% fails to annualise.
