will not be out of business, and have good upside potential.
So, those stocks will not go down much when there are further downgrades,
but will go up a lot when there are upgrades.
Do not buy those high-tech related, because they are just too much relevant
to the ecosystem. If the ecosystem is shrinking, it's very hard to turn
around. I like to buy those commodities related. Oil is oil, people don't
care too much the oil is coming from which company. | d******5
