Im not fussed over this for 3 reasons:
1) i dont have exposure to US banks and my exposure to australian banks has now dropped to less than 10% of the portfolio. My direct exposure to resources is zero.
2)if global stockmarkets crash over this, then just imagine the even bigger future crash if nothing was done. For investment banks 2009 now the year of a lifetime, effectively borrow from the fed at zero % interests and buy just about anything that gives you a positive return. Hell you can even make 6% guaranteed return by playing the oil contango trade. Now 6% doesnt sound like much, but if i do a 90% leverage with zero financing costs, thats a 60% return, guaranteed with my only risk factor being increases in future fed rates.
3) i think you will see stock rotation supporting the indexes.
I should also add that for once i am in agreement with the 'experts'. I am very weary of index performance for the near term (ie a couple of years), i think stock picking will be very importance as opposed to buying the index.
And this is exactly what we are seeing now, especially point two (which is why i was underweight banks on the way down). You have to take into consideration the carry trade when making buy/sell decisions (i dont own resource companies so cant really comment on this sector)
