The daily trading volumes of the companies I watch are generally about 30% lower than normal. I don't see any longterm hiring happening yet.
KCS share price benefited because: 1. its share price was much more elastic than its peer group because about 25% of its shares were liquidated by hedgies--i.e. the bounce back resultant from an oversold position was much more evident.
2. it is the only railroad that is developing a new market (i.e. Victoria/Rosenberg, allows it to compete with the cross border trucking business in that corridor). This gives it an increasing weekly carloading count.
3. the resolution of the battle between Ferromex/KCSM trackage rights.
