Michael, You ask a lot of good questions - let me make a couple of comments and then I will finish off with a table with 2 different sorts.
First of all, in general, the stocks within the Group tend to move up and down together. The weak, usually smaller stocks, move the least amount, the next is the Generals in the Group that move well to the upside, but are limited because of their size, and the final group is the "medium size" stocks with good technology that really move, both on the upside and downside I might add.
I put the following table together, portions of which I have posted several times before to illustrate the point. The first 3 columns in the table show the performance of the Group from the lows set on 10/8/98 and their respective high prices set in 2000. Two stocks at the top jump out at you, PHTN with a 3917 percent gain and LTXX with a 3736 percent gain. TER, AMAT, NVLS and KLAC, the 4 stocks in the Group that are part of the SOX were up 1307, 928, 858, and 791 percent respectively. Tremendous performance but pretty puny compared to PHTN and LTXX.
Now lets go to the last 3 columns. Note that while the sort is not in the last column, since the low set on 10/9/02 and comparing to last Friday's close, PHTN and LTXX are clearly in 1st place again with gains of 1268 and 1065 percent respectively. Based on past performance during the 98 to 00 runup, and the fact that they are again in 1st place now during the most recent runup, I would think they may very well wind up at the top again at the end of this bubble. Also, by the way, we are well on our way to a new bubble top as the percentage gains since October show - still have a ways to go, but now the Group is gaining a full head of steam. Like Needham said this morning as reported by Briefing.com
<With cycle-to-cycle growth, semiconductor equipment stocks could reasonably be expected to yield returns of 50%to 100% or more over the next 18 to 24 months.>
Anyway, here is the table, first sorted by the 3rd column and then sorted by the last column.
