re: your first sentence in the second paragraph.........therein lies the condunrum regarding AIM buys or any dollar cost averaging technique, doesn't it?
.....let AIM fill the bucket on the "LAST" buy.....just how does one know in a falling market that "this" is the last buy?
The filling the bucket, as the market declined in '01 &'02 is precisely why most ran out of cash early, imo.....
Using the halfway to the wall concept is one approach...another is to increase SAFE to slow the depletion of cash...I would rather be able to buy a smaller amount at a lower price, if the decline continues, than to be tapped out.
referring back to your message, IF we could know it was the last buy called for by AIM.....we could indeed load the buckets, pails, washtubs, and even the bathtub at those prices and get rich.
