I just pulled in his worksheet from that link and ran it for a few of my holdings, just to see.
the 8 years had more to do with how long I've owned them than anything else.
I was just playing around with it.
Is there any advantage to running weekly as opposed to monthly? I've been using monthly because of the recommendation of monthly by Lichello.
Lichello also said that it doesn't matter to AIM if you do checkups weekly, daily or hourly. But keep in mind that he wrote that well before 'ALGORE' ever invented the internet. His first edition was keenly aware of high trading costs (mostly <$10 now). He also recognized discount brokers (later I think).
But mostly I think it depends on how much time you want to spend managing AIM. Monthly is just fine if that's the way you want to do it. Just personal preference.
As to one being advantageous over the other? I don't know. But I've stated a number of times out here that, to me at least, there is nothing magic in the market about a week or month. I actually/effectively manage my portfolio/basket on a daily basis (constantly minute by minute really). This can be done if you use GTC Limit orders (with extended hours) for Sells and Stock Price alerts for potential Buys. In fact, many of my transactions have occured in Pre- and Post Market times. Would have missed many had I just taken the monthly or weekly close, ran the calc and decided whether to make a trade on the next market day.
But then again, AIM is really my only hobby so I don't mind the time I spend on it. The fact that I can make money on a hobby rather than spend money on it is a plus!
BTW, check your gmail. I finally responded to yours to me from early August.
