Hi Ls,
There are many things to consider, and different strategies for different situations. Too much to analyse :)
The better behaviour is a nice point. These days there are the Lifestrategy fund series to tackle the behaviour problem.
I like the strategy of AIM buying at the lows and spending all cash. And then take a B&H approach. Especially with broad indices. I have noted with AIM machines that there were times that in hindsight this was very desirable.
Thanks, K
