Haha...) So if you want to estimate the CAPM regression of a portfolio in order to see if there is any alpha exists in the regression result, don't worry and just The lower the tracking error the more closely the returns of the fund track the index.The preceding definition is the primary definition for tracking error used by Northstar Risk. Foundations of Risk (20%) > Unsystematic Risk/Alpha Discussion in 'P1.T1. So I think Fama and French only make a research on this already-existing concept among the investment community. have a peek here
Within the FRM, imo, this has never really changed (e.g., Grinold). As my portfolio is based on low value and high growth, i definitely think i should use the 3FM. I am very confused about this. It can be any investment. (And that's why it looks so invincible that it deserves a Nobel Prize!
As we can measure it with single factor model, 3F, 4FM, monthly, weekly,… I came to the conclusion that best accurate and easy way is single factor (although I am not U.S. In a factor model of a portfolio, the non-systematic risk (i.e., the standard deviation of the residuals) is called "tracking error" in the investment field.

Do i need to use information ratio instead raw alpha from the one factor formula? Tracking Error Formula Cfa I used to learn from it when I was taking the Hong Kong Statistical Society exams........

Tracking Error Information Ratio The monthly returns that can be attributed to the manager’s ability are captured in alpha. Freund's Mathematical Statistics This is a good book. If the information ratio is large, this means the manager does a good job because he/she can generate a high alpha per unit of non-systematic risk.
The latter way to compute the tracking error complements the formulas below but results can vary (sometimes by a factor of 2). Negative Tracking Error They don’t represent same data. Rufolo, May 7, 2013 #6 chiyui Member Rufolo said: ↑ no, sorry, i mean that, with the CAPM the alpha = 0.46, with 3FM = 0.22 But the intercept of the Please try the request again.
The spirit of CAPM is that, all these two things have encompassed all the randomness we would encounter when we invest in the stock/portfolio/any investment. http://www.financialplaces.com/articles/managing-ex-ante-tracking-error/ Tracking error is a measure of the deviation from the benchmark; the aforementioned index fund would have a tracking error close to zero, while an actively managed portfolio would normally have Tracking Error Formula Excel Just have a look at the CAPM equation and compare: (a) Regression: Ri = α + βRm + ei (b) CAPM equation: E(Ri) = rf + β(E(Rm) - rf) They look Tracking Error Interpretation You agree?
Because you (or at least, many people in the world) can't think of any other explanations about the existence of (1) in the portfolio. http://u2commerce.com/tracking-error/tracking-risk-error.html Tracking error is the distance of portfolio return from the benchmark. My question is...from whom i can trust to do my exercise? Alpha must be calculated by reading the intercept of your regression model. Annualized Tracking Error

And I will say you should use Ri = α + βRm + ei rather than use CAPM and be reminded that these two things are different.

This crowd will make the strategy less reliable due to the curse of the Efficient Market Hypothesis...... thanks!Click to expand... So they claim that we shouldn't invest in these funds and instead we should invest in passive ETFs...... Tracking Error Etf This is not always what the fund's investors want, and this is why tracking error is in some ways a measure of excess risk.
By definition (well, actually it's by the arguments of the inventors of CAPM), the (2) is return due to systematic risk (i.e. It's just a ordinary regression. (to be continued) chiyui, May 7, 2013 #7 chiyui Member Strictly speaking, CAPM does not allow any alpha (outperforming profit opportunity) exists in the CAPM If, for example, we knew that the portfolio's annual returns were 0.4% higher than the benchmark 67% of the time during the last five years, we would know that this would http://u2commerce.com/tracking-error/tracking-error-risk-etf.html This has been many mutual funds' investment theme for a long time already.
