Will the stock market plung when ratings of mortgage-backed-bonds are lowered?

S&P, Moody's and Fitch have warned that they may lower the credit ratings of subprime-backed-bonds.

When they actually lower the ratings, will we see a plunge? a correction perhaps?

 

the opposite will happen, stocks will soar and the DOW will be up another 20% within 3 months.

 

No it wont it is only going up medium term
