shows that many of the added stocks traded 10-20 times their average 3 month volume on Friday. I noticed that it was not uncommon for the additions to be up 3-5% nor was it a sure bet as many were also very near unchanged on the day. The only thing real consistent was the huge volume jumps for the stocks that were added to the indexes.
Even the biggest of the big Berkshire (BRKB) was up nearly 4% on 15 times it's normal volume. To try to read into Fridays activity as being some kind of signal to buy Wave is just plain folly.
