Arbitrage portfolio - factor model
1) In what significant does the APT differ from CAPM ?
2) Why would an investor wish to form an arbitrage portfolio ?
3) What three conditions define an arbitrage portfolio ?
4. Assuming a one-factor model, consider a portfolio composed of three securities with the following factor sensitivities:
Security --- Factor Sensitivity
1 -- 0.90
2 -- 3.00
3 -- 1.80
If the proportion of security 1 on the portfolio is increased by .2 how must the proportions of the other two securities change if the portfolio is to maintain the same factor sensitivity ?

c APT does not tell what the underlying factors are unlike CAPM which relates the return on the asset/portfolio of assets
on a single factor (the return on the market portfolio).
2) Why would an investor wish to form an arbitrage portfolio ?
An investor wishes to form an arbitrage portfolio to increase ...
