I started investing about 6years ago. I have an account with Ameritrade. I own stock in 3 or 4 companies, and am not as active with it as I once was.
Initially, I picked a large company that showed BIG promise in growth and profits and so far that bet has paid off quite well. I'm in for the long run so that one sits. It recently split two for one and I wish I was in a position to buy more shares at the lower price.
One of the other companies that I invested in was little more that a start up. It was basically a "penny stock". They went out of business shortly after I invested.
Em, no matter what kind of education you have, or get on investing, there are no guarantees. The Long Term invester has advantagesin that if for some reason a stock tanks, or all of them do, over time, you can bet that eventually there will be some sort of rebound and you will get your money back.
Getting rich seems to me to be for the rich, priveleged and lucky. Stock investing is fun, challenging, and educational, but in no way is it a guarantee of retirement wealth, or college fund building. There is no way to know what shape the market will be in when it's time to retire, or time to put the money into a college.
As obvious as it is, it must be stated and remembered... Buy Low, Sell High. That means that if your stock tanks for some reason, don't panic and sell for fear of it going lower. Let it rebound. If it's a good stock, buy more at the lower price, but don't sell existing stock.
Read Fortune magazine. Read the Wall Street Journal, and any other reputable business/investment ink that there is. There are some good FUNDS that you can invest in that are safer than stocks, generrally make more money, but you have to play by their rules (maturity, amounts...). These funds are rated, reveiwed, and disected alot by Fortune magazine.
My Aunt did really well for my brother and I by investing in the Magellan fund. By the time we went to college, the funds had matured and had done fairly well. It didn't cover all the bills, not even close actually, but it was a HUGE help.
The most important advice I can give you is that you shouldn't invest any more than you can afford to lose. You have to take a chance, but you have to consider covering your azz if the market tanks again. In general, the stock market is a good place for your money and Long Term Investments do pay off. It's just a matter of being smart, moving your money when the time is right, and a little luck never hurts.
Oh, don't jump on every "hot stock" that friends may recommend. I lost a significant amount of money over the last couple of years on a stock that I bought on the recommendation (hounding) of a couple of friends. Do your own homework, and make your own decisions.
Good Luck!
