Quote from FredBloggs:
Ive noticed one thing about mm -
all us retail dudes talk about 1% 2% 5% etc of capital to risk on a trade, monte carlo etc
all the pro traders ive spoken with (pro = in a bank trading other peoples money) laugh at the idea of mm especially x%. How can you win with such small size they ask. their idea of mm is over or under committed to a market. if their gut is pushing them, they put the whole farm on the position.
does any one trading their own bucks take this approach?
i assume that what you call pro traders are traders on desks in institutions. they never think in terms of capital, that is why percentages never mean anything to them. i think this is the weakness of these institutions not their strength. in quant hedge funds and ctas, who are in my opinion trhe real "pros", nobody will laugh about you when you are having fixed rules interms of percentages.
i would admire your "pros" too much. it is a different story and there are many quite absurd things, like their decreased risk appetite at year end and year start. only due to the strange bonus payment usages there ...
