Singer-Terhaar and adding securities to portfolios mkt, notice, should

Iginla2010

Anyone else notice that these are basically the same thing?

RP(asset class) = Std Dev(asset class) * Corr * sharpe ratio(mkt)

or

RP(asset class) / std dev(asset class) = Corr * sharpe ratio(mkt)
which is:
sharpe ratio(asset class) = Corr * sharpe ratio(mkt)

So basically:
Singer-Terhaar says that the SR of the asset class should equal the mkt SR times the correlation b/w the two.
In the context of asset class selection if the asset class SR is greater than portfolio SR * correlation b/w the two you should add it to the portfolio

I have no clue what you are talking about. You threw me off by using the RP. What is RP? What is SR?

I expect it to be Risk Premium and Sharpe Ratio

Looks pretty sound and accurate...Does the book say it's an approximation?

yeah, there was a question similar to this on the Schweser mock. BTW does anyone else feel that the multiple choice sections of the Schweser mocks are not representative of what will be on the test? Feel like its just rehashing the q-bank.

i saw this on another thread but don't want to hunt it down so im kidnapping this thread.

Somebody said you add the liquidity premium to both segmented and integrated markets risk premia, is this correct? I thought it was only segmented....

nannan66

say whaaa??? no way man im pretty sure you add the liquidity premium to both.

wi*LP+(1-wi)*LP=LP

So it ends up with same LP -- liquidity premium added.

i dont know what all of those fancy symbols mean deriv, but i think you add the premium
