Long time AIMer here and been following this forum for years.
I've observed some people use one stock, some multiple stocks, and other ETF/funds. Most of my AIM accounts are either 2+ individual stocks or ETF/mutual funds. While not as volatile, I have found the discipline for buy/sell over the years has given peace of mind by taking a lot of the emotion out.
The current environment reminds me of the mid-1970's with stagflation which AIM was designed to help navigate. Having cash in a sideways market where you might not be buying/selling is at least spitting of some nice interest. While we are not seeing 9% passbook rates, I was still able to see 2.75% on my cash position over the past 12 months. Not thrilling I know, but when compared to the market it's not too bad and contributed to a 3.25% gain overall for my largest AIM account last year. It also didn't hurt that I invested in commodities funds & dividend issuing stocks which are not typical AIM performers.
Anyway, thanks for "listening".
