As a part of my reserach I am forming portfolio from market indices. I am interested ifCan the CAPM bettabeta of emerging markets can be less than the onebeta of the developed markets.
When I say CAPM betta I mean the following:
for example ASIA market:?
Expected return(ASia market)=Riskfree rate+ betta*(ReturnAs part of Internationalmy research, I run regressions using market-Riskfree rate)
As indices. I estimate the beta using a regression of MSCI country/region excess returns on the excess returns of the MSCI ACWI. Excess returns are returns minus the risk free rate I take t-bill
As a international martketfree rate (which I take to be the allT-world market index
whenbill rate). When running the followingthis regression, I got afound the following strange result:. While the bettabeta of CHinaChina is less than 1 where, the bettabeta of the USA and of Europe is moreare greater than 1.
Any usefull comments are highly appreciated, Pasha Can anyone please explain this result?
