Quote from drcha:
Last year, 18%. This year, so far 13% annualized. My backtesting indicates that 15% is going to be about average. As you might expect, about half of trades are losers. Winners are much larger than losers. Average holding period is about 3 months.
I backtested several MAs and decided that if I wanted to use only one rule, the 200 and the 50 constituted the best compromise. Maybe there is a reason why these are the "default" MAs. They seem to work best in most situations. And I think it is best to pick a set of MAs and stick to them. Otherwise there is too much curve-fitting.
I take most, but not all, signals. For example, if I am long the Aussie and the Loonie posts a signal, I do not buy it, so that I do not hold two commodity currencies. Therefore, when there are highly correlated signals of this type, I end up taking the one that has the first signal.
My impression is that this works best on commodity, bond and currency ETFs. Stock ETFs, not so well--they are too volatile and too bandied about by earnings and news reports.
As with any trend following method, there are some periods with a lot of whipsaws. You gotta stick with your rules.
After a quick perusal of SPY on Yahoo charts, it seems using the 50 day gives better results than the 200 day. There were several cases where it got you in at a lower price and out higher, and a couple of cases where it got you in for a profit where with the 200 day you would have stayed in cash. Of course that means more trades, commissions, tax hits, etc. Needs more testing.
BTW, what do you use for backtesting?
I saw your review at Amazon. I have ordered the book.
