IR risk - vodka at stake?

but if the interest rates go down, economy will expand, incomes will rise, more parties will be held and so the demand for vodka will increase causing an increase in the price, what do you think about that?Siberian

trade sharpe vs. daily sharpe and sampling frequency

<t>but my point is exactly that the frequency of trading does not matter because of the way returns are measured. say you have a macro guy who rebalances every say 3 months. if we were to mark-to-market based on his investment horizon then in 5 years we have only 20 returns from which we can calcula...

trade sharpe vs. daily sharpe and sampling frequency

South Ossetia

<t>I am sorry scholar, that is just a silly thing to say... Countries are fine where they are, they just have to be smart...If you read the report by the HRW, the genocide or attempts of thereof were recorded on both sides, and it is not clear who started it this time. The military operation was sta...

Very simple dispersion option pricer

oops, silly typo, it is of course sqrt(YrsTM)...centroid is just a mean return, dispersion in this case is the MAD (mean absolute deviation)the rest is just simulating the return N times, averaging out and discounting.thanksEv

Equity L/S perfomance measure

<t>IR? Sharpe?you can use a tracking error and a vol estimate to come up with an implied notional, take monthly pnl (net of bmark like t-bills or whatever other cash bmark you are using) and divide it by the implied notional to obtain a % return;some FoF are using monthly value add divided by the (m...
