Woow there!

UBS has INCREASED its holding form 5.1% to 6.14%. Campbell Bros will not be happy/nervous if this is a totally independant holder. Over 10% , of course, can indicate greenmail, with a protracted negotiation (and higher price) for CPB to mop up the holdings not taken out.

Or are they just doing holding shares for arbitrage - buy at - say - 3.95 and transfer to CPB to sell CPB at a profit? (If so, why still holding?)

Any ideas?
