I've made a lot of money buying falling knifes, particularly bluechips sold off after profit downgrades. Have a look where these companies were 6 months after downgrades:
syb
all
cpu
bhp
mia
rmd
csl
coh
Notice also how many of them were exposed to similar sectors (health).
I'll put a case of beer to say SIP will be above $2 before the end of August?
