I've been studying finance and investment management for a few years (chartered financial analyst designation), I worked in asset management in Canada and now work in corporate finance in Switzerland. This doesn't make me a great investor but it's given me a great view point into the behavior of investors.
What boggles my mind is that you would ask this forum. Nobody knows what the markets will do in 1 week, 1 month or 1 year. Only fraudsters report to know.
The one truth is that markets have generally gone up in the past, over the course of many years. The main problem is that they climb a long wall of worry but take the elevator down.
Investors face many biases and recency bias is the one we see most often given the financial crisis. Otherwise, the moment markets go down, people start thinking that a new financial crisis is upon us.
Market have suffered a 10% drop about once per year on average and a 20% drop once every five years on average. The one implication from this is that if you think you might need the money within a year, don't put it into stocks. That's what money market funds are for.
If you believe in capitalism, that businesses will keep on generating profits over the coming 20 years and that you won't plan on touching your money for at least 5-10 years then investing in stocks is a great way to build wealth (once again, over the long term). But if you hope to make a quick buck, then a trip to Vegas will give you the same odds.
Sorry to disappoint you, but doing what you did in the first place was not the smartest of moves. Compounding that with asking this forum was just dumber. And blaming people for given you advice on whether it's been heads or tails is probably the dumbest.
Given the biases you are prone to, your money should not have been in the market in the first place.
Sorry bud!
