Hi JDM,
You'll note on my graph that the TLT treasury fund peaked in 2012 and had a pretty crummy year last year. Generally it's nice to start a new AIM with something that is out of favor so that if nothing else one can get some gains from 'reversion to the mean.'
At least for a while, TLT has stopped going down. It is currently paying ~3% which is actually up from a while back. So, maybe now is a good time to think about starting such an AIM account. Even blended with some cash the yield will be better than a pass book savings account!
There's enough amplitude to make AIM work with the longer maturity bond funds. The "frequency" isn't very high, but the amplitude is good. Low BETA in this case means something that will usually be countercyclical to the stock market. Having something that is generally non correlated to the market can add balance against stock of stock fund holdings.
Best regards,
