Do you think the FED injecting trillions into the economy had anything to do with that ? Do you think in will keep going up because the FED's money or because of a booming economy ?
No, the only industry that was significantly helped by the injection of money was the automobile. The larger companies responded to the financial crisis by laying off lots of workers and cutting costs. When things began to get better they realized that they could make large profits and still remain lean. The whole economy is not yet booming but it certainly is getting better and the large public companies are doing quite well.
