Could you explain in words please why you think a trend following approach isn't well suited to trading short. You mentioned this on another thread and included a couple of links to support your case, but I couldn't make any sense of the info in those links.
I see no reason why a stock that's in a nicely established downtrend can't be traded short as long as the downtrend continues. In fact I've ridden a few of them myself.

Bunyip,
You sure can short stocks profitably, but it depends on your time horizon whether it will be succesful in the long term.
If you are take short-medium term trends (trades that last a few weeks only) or take swing trades, shortselling works fine. I made most of my income last calander year from short selling swings.
But if you trade the big trends, such as tech/a's system, it won't work.
Long term trend following really relies on fat tails in the distribution of returns to make it really profitable. That means you keep getting stopped out or picking up only small wins, until you pick up that one (or few) really big trends. Eventually you're sitting on nothing but outliers if you happen to be in a bull market. But thats why they take a while to get going.
But on the short side, there is no such thing as a relly big outlier, because you can only go to zero... and even that doesn't happen often on shortable stocks.
It's easy to prove. Just backtest it. Take techtrader for example and test it on the short side only. It doesn't work.
Remember we are talking about
long term trend trading. Other styles are a whole 'nuther bowl of wax.
Here's an example: (assuming both traders trade on margin)
Trader (a) trades a stock from $1 to $11. He has made 1000% profit on the unleveraged amount.
Trader (b) trades the same stock from $11 all the way back to $1. That trader only made ~90% profit on the unleveraged amount.
Thats different from swing traders:
Trader (a) trades a stock from $30 to $33. He has made 10% profit.
Trader (b) shorts the stock from $33 to $30. He has still made 9.1%
Different situation alltogether.
Cheers
