Learn technical and fundamental analysis methods on stock market and do your own research instead of giving your money to a fund manager or broker. Majority of mutual funds could not even beat market index for the last 50 years, your guess is probably just as good as "professionals". The key difference you need to have a discipline in money and risk management. Usually this means don't invest everything into one or just a few stocks. Diversify as much as you can to weather the storms. Also try to overcome your emotions of greed and fear. A good book I recommend is "High probability trading" by links.
My view on investing is people amd especially media try to oversell the important of "breaking news", and people flock to buy the stock if there is a good news, and sell the stock when the news is bad. You do not want to become a "news" trader, because when the news comes out the price action is already taken - the news is "priced in". you are already too late. Do not subscribe to any financial news and spend hours and hours looking for the latest news because there is always 10000 people ahead of you. Instead try to predict what is going to come out. My experience is there is no better way the using good old fashions chart pattern analysis. Strangely enough, news always come out in time to form and shape the chart so it fits the patterns. Sometimes even bad news gets interpreted as good news just so that price movement fits the pattern, so go figure. One website I recommend is
www.screenulator.com it is non-profit unlike many other fancy looking stock sites, but has great number of chart patterns screened daily. You can also get free charts from
www.stockcharts.com, and basic tutorial of chart analysis. You have to use your judgement though, they do not just tell you which stock to buy or sell, you need to know some chart pattern basics. It is literally a gold mine for me. I have made tens of thousands using trendline analysis category.
