Always better prices. I emphasize it again: you always get better prices than the futures give you. It's a nightmare to just blunder in when everyone else is -- this time, because China might be holding.
We are in earnings season, which is why I care about the dollar, and the dollar is going in the wrong direction, which makes a huge percentage of the stocks that rallied big at the opening just plain wrong.
So be careful of the stocks that need a weak dollar, like Caterpillar (CAT), the oils, Cummins (CMI), even one of my faves, which is in the Action Alerts Plus charity portfolio that I co-manage, 3M (MMM), to name a few, that don't "deserve" to be up on China, as they will go down on the dollar's strength. And yes, the oils will and are going down, too.
It is why my caution will never end on the up openings.
You want to buy now, down big from the opening. I can live with that. But not when everything is up. That's a sucker's game.
