Hello Jack and Bernie,
Just wanted to point out two things on this topic.
1. With Automatic Investor, when using the historical analysis feature, you are provided with a line by line report documenting each trade including the date, share price, number of shares traded, total shares remaining, Total security value, cash reserve, portfolio value and portfolio control. In addition there is a detailed summary that tells you the settings, returns, B&H returns, plus much more. You can also annotate this report (right on the screen) and save it to a file -- which can subsequently be printed. This not only gives you a record of WHAT the results were, but also HOW you arrived at the results. And it's on paper so you can review it again and again. I think reviewing a number of these reports is a great way to learn about AIM.
2. With Automatic Investor (and PCA) you can always decide not to use the automatic historical analysis feature and simply enter each price, see the results change each period, and make the decision whether or not to follow the advice -- just as you would in Newport. Doing this one or two times might be a good exercise for new users (and I have personally done this a few times). However after the 100th time, I know I'm very happy to review an auto-generated detailed report rather than having to go through the entire manual process again. To sum up, AI and PCA don't stop you from performing the manual process (similar to Newport), they simply add an automatic historical analysis feature (and AI adds a detailed report to this feature).
Hope this helps a bit.
regards, Mark. |
