The question isn't: will the US market take a serious downfall, it's when. The US economy is based on ethereal transactions and made-up values driven by stock market criminals. We no longer have an economy based on real goods and services. The backbone of the economy is non-renewable energy that allows for transport of junk "goods." This is why the market will fail.
The US market is definitly on the brink of a downturn, Everything that you buy in a store has skyrocketed even the smallest item that you were able to get before cost a fortune now. The way the market is now nobody can afford to live anymore when it cost so much just to feed yourself in a day.
No, the U.S. market is not on the brink of a downturn, because we have been going through a downturn for several weeks. What we have now though is only a temporary cyclical set back. We don't have a full-on economic recession like we had before. This is only a blip, but things will get better.
Although scared experts and doomed specialists speak loud of the US market downturn and the recession, it is highly doubtful they are right. Yes, the economy is not in its best years but the festive season is here and also the end of the year. This is time of huge spending and positive expectations. The real economy situation can be justified in end-February or begging-March next year, when sober analysis can be made.
