Stock market is a gamble no matter who or what, over the years it's crashed for a number reasons under a number of presidents and lately it's not even logical what it does, add to that the feds pumping money into the bottom end of it, sometimes it's gains are downright artificial and you can bet it will "adjust" to this as well.
What I find interesting is Obama's campaign...he openly on national TV was totally against the government raising it's debt level, said it would hurt our children and gave all the conservative reasons to vote against it. After he became president, no problem, raise the debt and spend and he wants to do it again...go figure. He is not only the same as Bush was, he took it to a new spending level unheard of before. Matter of fact, nothing in his campaign was done, he has done the exact opposite of everything he ranted and raved about.
Government is out of control, it has been for a long time, the current president added to that many times over, with the help of congress who writes it all. Things have went down hill the last few years, and it's much worse that what they tell you, they fudge the numbers to make it look just real bad...it's worse than that.
