obiwan said:Faulty arguments I have heard about mutual funds :
1. They charge too much - then get an index fund (MER 0.5-1% pa).
obiwan said:Index funds are great, I am a big fan. If you are paying a 2% entry fee, you are being ripped off. They should be refunded if you buy smartly.
Now what I get from CAPM is that variance is related to risk which is related to return. What it shows in a roundabout way (with some unrealistic assumptions) is that you do not get an excess risk adjusted return for taking firm specific risk.
Basically YOU DO NOT GET AN EXCESS RETURN FOR NOT BEING DIVERSIFIED. You can take on more risk by buying individual shares (a portfolio of 1-5 say) but you get a LOWER RISK ADJUSTED return than the market portfolio. It is actually a very profound concept and counterintuitive initially.
Hmm you mention that this is a concept rather than factual.
I can prove using the 2 positive expectancy trading models I trade that Having less stocks in my portfolio will give me greater return.
Define for me your understanding of "Risk adjusted return" ??
Ok say you buy one stock, this has a higher variance than the index. What CAPM implies is that adjusted for risk/variance, you do worse than a basket of stocks or the index. Mutual funds are a cheap way to access the 'index', what they have done is make available to retail investors who would otherwise only be able to afford a few stocks the benefits the RAR on a market portfolio.
Instead of buying an individual stock you could for the same variance buy the index on leverage with a greater return.
Daytrading : Even Livermore said that he didn't find it profitable. He said you make most of your money on the primary trend or countertrend. He said very short term trading is a lot of noise and obsessing. Someone described it as like masturbation, this repetitive, obsessive, ritualistic activity. Not a good thing to do all day for you balance sheet or mental health.
Yes agree usually sends the participants BLIND to any other form of trading.
These are normally those who want to turn $10K into $1 mill tommorow and who believe that 100% profit trades are common place. Still there are methods which will outstrip Mutual funds by miles--I chose to trade these and they dont have any more risk infact Id argue less risk than Mutual Funds
obiwan said:actually, I don't want to sound too negative about finding a system. If you feel you need to do it, keep doing it. However I am just warning you that it is not likely to be a way to riches (or at least a better way than mine over 10 years.
Ive actually stopped "doing it" and am trading it.My trading returns over the last 2.5 yrs exceed your returns for the next 10 so if I stop now???Thanks for the warning.
'I can prove using the 2 positive expectancy trading models I trade that Having less stocks in my portfolio will give me greater return.'
Absolute return is not important. The critical variable is variance/ standard deviation of returns. You can always lever up the portfolio : this increases absolute return but also variance by a proportionate amount. The risk adjusted return can be measured by eg sharpe ratio =S(x)=( rx - Rf ) / StdDev : (x)
x is your trading portfolio
rx is the average annual rate of return of x
Rf is the best available rate of return on a "risk-free" security (i.e. cash)
StdDev(x) is the standard deviation of rx
Ahh I love NUMBERS.Standard deviation on 20000 portfolios has been shown to be less than 3%,with none of the outliers being negative.My software doesnt calculate the Sharpe ratio---I think Amibroker does so Ill ask someone to supply it out of curiosity,still it wont have an influence on what I do.
Also if you are trading on maximum margin, and your max drawdown is say 20% you need to add this to your capital base in calculating return on portfolio : ie 30% margin, 70% loan, 20% in reserve trading fund. Capital is the 30% + 20%, and returns should be based on this.
You mean portfolio drawdown,and I believe you also mean INITIAL Drawdown not Peak to Valley Drawdown.In which case the issue isnt an issue once your portfolio has enough profit to cover initial drawdown.
The Sharpe ratio is only one method of "argueably maximising" use of funds.There are others and are worth considering IF your using huge sums of money and can employ an analyst to keep check on your Sharpe ratio or any other ratio.Im not an institution(perhaps a legend in my own lunchtime!) and as far as I know nobody else here is either.
