But none of the foreign companies have proved any better than the Detroit Three at predicting how gasoline prices would gyrate or the extent to which demand for cars and trucks would collapse in a deepening recession.

Can I rephrase the above sentence like this below with little change in meaning? (I did it for my better understanding.)

The Detroit Three did not predicting either that gasoline prices would turn around or that demand for cars and trucks would collapse substantially due to a deepening recession, but neither did those of foreign companies.

Thanks.

Thanks so much, Cbsteh.

But do you really think Detroit's Big Three domestic companies have been best in such terms? Emotion: big smile

Could you tell me what "gyrate " means here?
