I don't think so. The stock is up slightly today on the news. Of course, I have no idea where the stock will be trading at then.Berkshire Hathaway announced that a 50-to-1 split of their b-class shares will occur to accommodate the shareholders of Burlington Northern. This means the stock will be trading at around $66.
I suspect this will drive retail investors (aka Warren Wannabes) wild and will drive the post-split price higher based little on fundamentals.
