Buy Low,
Portfolios often get rebalanced, maybe once a year or at certain deviations from an allocation percentage.
This practice is referred to as Buy Low, Sell High. A contrarian type of Money Management.
However it seems to me that this rebalancing not always is Buy Low, but for example Buy Medium, dependent on the situation.
Aim is doing a better job of Buying Low, AIM never buys between High and Low. At least that is how it seems to me.
So in an investment portfolio, one can typically specify the range of each asset class allocation, to 'time' the market. (see for example R.C. Gibson, Asset Allocation, Balancing Financial Risk)
This step in the portfolio management process can be handled by AIM. Aim makes it a mechanical driven and not management driven process.
