Fred Barnes is dreaming. The market isn’t reacting to the future, because the future isn’t here yet.
In other words, the market reacts to what’s certain today.
If the market was reacting to some unknown, inside information that Joe public investor isn’t aware of at the same time as any other trader, that would be illegal. It’s called insider trading.
The conventional wisdom is that the market looks ahead six months to a year, trying to anticipate developments. I don't think much of this idea but it seems to be a popular notion when pundits wax financial.
