During the Bush market meltdown it was shown that the stock market is a 'sucker's game'. The whole market was being used to bilk the small investor. Big brokerages were found to be doing insider trading, manipulating stock prices, and selling stocks to their trusting customers that they knew were bad stocks, so they could bet against them. The market is tilted towards large 'institutional' investors.
So my advice is to NEVER EVER EVER take advice from a broker. They will recommend stocks that work well for -them- not necessarily for you. IOW they make money even if you lose money.
What you should do is to get an account at a no-commission brokerage, like Charles Schwab (not Schwb in particular, that's just an example). Then ask for literature on Mutual Funds and ETFs (Electronically Traded Funds). These have records of how well they've done in the last year, the last 5 years, and the life of the fund. Find a few that have done well and divide your money between them. They should be in different 'sectors' because when one part of the market does badly others often do well.
Buy them, put them away, forget about them for a few years. Don't check them every day, don't constantly buy and sell trying to improve your position. Years ago there was a fad for 'day trading' and a lot of people lost fortunes doing that.
