Hi,
When I started using Newport I started updating weekly and doing trades twice a month. with all the euphoria that existed from '98 on I soon began trading weekly, updating my files on Friday night and putting in the orders on Monday morning.
When great decline started in 2000 I began to see the error in this thinking.
I started by doing some what if simulations on my own stocks and found that all the discussion that were occurring on how how to slow down AIM's buying were unnecessary. Updating AIM programs monthly slowed everything down very nicely indeed. Makes life a lot easier too. I do my updating on the first day of the month, only because every month has a first day. If we are on a trip and I am not at home on the first there is nothing to worry about as I do my updating on the first day back from the trip.
While it is true that there have been occasions where I have missed making a trade, there have also been occasions where the trade has improved. It really isn't worth worrying about pennies. Using Newport I update weekly, just to keep the graphs accurate. I do not even look at the Buy/Sell recommendations until the first of the month. I have quite a few low volatility stocks which work just fine using this method. One of which is TWGGX, a global Mutual Fund, which only fairly recently turned negative. I will be buying some more of it next month, and there is enough Cash Reserve for about two more buys.
