What an important question you ask LL
This question..., and the answer - is what a trader (meaning one whose transitioned from the journey of becoming a trader - to trading centric ) should (must) be continuously focused on..., understanding..., managing..., owning - imo
@
Redneck: Made me reflect if this (% of return) is an important question in the first place. Please allow me to verbalize my musings. They have not been vetted, so I could have committed some grave fallacies of reasoning. If so, please feel free to point them out.
What came to my mind first were the words of Franz Kafka:
"Better to start right than to start with what is acceptable"
I know measuring performance as a percentage of return is the acceptable thing to do, but is it the right thing to do?
For a fund manager
(A) A fund manager measures performance as a percentage of assets (
returns) not for the purpose of evaluating herself, but to compare her performance with her peers. This comparison is not an act done for the sake of itself, but has an ulterior motive -- the motive of accumulating capital. So,
returns, seems to me, is used as marketing tool to attract capital.
(B) But, the investors are not naive. They want to know how the fund manager obtained her
returns; so, they are interested in
returns per unit risk. Risk is a huge subject in itself. With an ethical fund manager, an investor faces two types of risk: (i) risk of capital loss -- this is a
knightian uncertainty. This cannot be measured ex-ante; (ii) risk of return volatility -- this assumes that capital investment will be intact, but the returns are volatile. This can easily be measured ex-post. However, when returns per unit risk is calculated only the return volatility is used as a proxy for total risk. This, although
acceptable, is not meaningful to all investors. In fact, the only group of investors that can use this measure are managers of Defined Benefit Plans. For our purposes, we do not have to go any further. Note: Leverage is not the same as risk.
So, a fund manager uses
returns as a comparative tool to attract capital, while the investor uses
returns, rightfully or not, to evaluate the manager.
For an Independent Trader
(A) On the surface, it looks like
returns could be used as a proxy to opportunity cost for an independent trader -- i.e., from an economic sense, do it make sense for the independent trader to do what he is doing give other opportunities available to invest the capital.
(B) However, this thought does not capture the intrinsic benefit derived by the trader by owning a business. So, the proxy proposition can be discarded.
(C) Is there any other use for
returns to an independent trader? I would submit that the answer is a resounding 'no'. A better measure would be ex-post expectancy for a period -- a period that makes sense to the Trader (and not any one else) based on his trading style. A
positive expectancy would mean the trader
should be in business; and the
size of expectancy would provide the trader a means to plan expansion of business.
For example, if a trader makes $10 net profit every 10 days of trading with $10,000 capital, then, in a year (assuming 200 trading days), the trader would make $200 per year. What is important is that the trader consistently make $10 very 10 days ex-post. The 10 days is picked by the trader based on his trading style (his understanding of this trade signal, # trades taken, yada yada yada). From a yearly return perspective, this could seem very small 2%, but we all know the business of trading is unlike many other business -- it can be leveraged. So, to make $200K, the trader would need $10M, but could use leverage. A path exists to "grow" the business.
Returns are useless 'cos the Independent trader is interested in earning a living for himself and his family; and, the absolute dollar-amount of net profit is what matters to him.
As a side note: I get an impression that many (or, may be, just a few) ET-ers do not understand the prop-house business model. Everyone understands a fund manager's business model and seem to think the same model applies to prop-houses too. In an another thread, when poster said that a prop-house had a 80% profit-sharing plan, one
responder responded stating that this was all non-sense for even the best hedge fund managers command 35% performance fees. What was surprising was that many readers agreed with that
responder. Only if that
responder had taken time to understand the difference in business models (and legal constrains faced by fund managers) he wouldn't had exposed his ignorance by making his claim.
For Trader in ET evaluating other Traders
(A) I really don't understand why one independent traders needs to
evaluate another Independent trader. Is it because for a trader to agree with another trader, one needs conformation that a trader is really a successful trader? Imagine the situation we would run into if a star NFL quarterback refuses to listen to his coach for the sole reason that the coach was not a successful NFL quarterback. Yet, this seem to reoccur again and again here.
(B) Or, is it because traders in ET are skeptical about other's success? If that is the case, then any amount of "supporting documents" is not enough. One can always, and for valid reason, ask for more confirmation. My question is (rhetorical of course), if one does not believe in a clam made by a trader, why not just ignore that trader and move on? Why all the rattling and finger pointing? If one is claiming success by lying, it is the liar's problem not the listener's, isn't it?
(C) In any account,
returns of an independent trader are not meaningful to another independent trader. It seems to me that what another independent trader should be interested is in a trader's expectancy --
not the
size but the
direction: Is the independent trader having a positive or negative expectancy. Note: This expectancy can be defined only based on the trader's period 'cos that is what makes sense to that trader.
When it quacks like a duck, and walks like a duck, most probably it is a duck. But the problem is one needs to be aware how a duck sounds, and how a duck walks before one can make the above inference. Maybe that is the problem here. Not very many people have seen ducks or are ducks themselves, so they have problems making the inference!
But then what do I know -- clearly very little!
@
Redneck, I would be interested in your thoughts on why you think this (% of return on assets) is an important question, and why a trader should be continuously focused on it. Definitely not interested in how much you make, for this doesn't help me grow my knowledge!
