Was wondering the same thing Yana, I could find nothing to trigger the buying. There has been no news or anytying pending. There is some shuffling of the deck going on which will not be announced till December.
Too early to predict Q4 results but some of the train schedule adjustments are paying off better than I expected this was reflected in Q3 and should carry forward with a bit of compounding into Q4 and forward. I bought some in the $90 range a few days ago but sold it the other day. Looking at adding each time it touches $90. Still think a split is in the cards.
