Regarding the example that should proof "exeptional performance" by Peter L. Brandt, I hope you don't mind if I reflect on it and remain sceptical.
If it's from himself I think it is a very poor sample with little credibility just looking on how it's made.
Audited period it states 1981 - 2010, a period of 30 years
Below 14 winning years, 4 loosing years.....what about the missing 12 years? Cherry picked?
Average compound R.O.R . 41.6%
Probably he means CAGR.....but without listing the number of years it refers to it's a worthless metric.
There are other easy measures one can take to be able to state a high CAGR.... that's one reason the finance industry loves it... ;-)
Furthermore by choosing the point from which you state CAGR you can massively distort the real picture
Then it states: Each 1000 USD starting capital produced 319000 USD through 2010
1000 USD / CAGR 41.6 % / 29 years would grow to 24 034 458 USD?
1000 USD / CAGR 41.6 % / 18 years would grow to 523 767 USD?
..... so explain what he calculates here...I can't reproduce it.
Again, for the MAR and CALMAR values he needs to state the period to which he refers to, otherwise worthless.
Most important: If you talk about audited results you list your auditors name. If you do it seriously, you list a copy of a signed off auditors statement. Based on the reputation of the auditor, one could make a reasonable judgement and even verify with the auditor if it is faked or not.
So I really do not know much about Peter Brandt's CAGR over the last 35 years, but looking at his business modell on websites like elliottwave.com and peterlbrandt.com I see him on the same track as Larry Williams, Ed Seykota, Linda Bradford Raschke, Birger Schäfermeier, etc. etc. there is a lot more value in selling the dream. An Forex Brokers worldwide do have hudge marketing budgets they are willing to put to work on "trading legends" to lure in new retail suckers....
