It would explode yesterday (23/03/2013)
Losing 30% of its value in few hours and than recover means the value is valid, don't you guys think so?
Although people tend forget that 30% decrease out of 75 is 52.5 while 30% decrease out of 20 is 14 the latter doesn't looks that scary as the first one
What you are talking about is totally subjective.
Personally I don't even give a second thought to spending anything less than a $50 bill...for some its a $5 bill and to others its a $10,000 bill (if they made such a denomination)
My point is that everyone has a comfort level in a market depending on their position in that market.
