In terms of stock investment research and planning, many people today try the age old "beat the market" strategy of watching numbers obsessively day-to-day and buying/selling accordingly. If you fall in this category of stock investment research, the best tip for you is to slow down and go for the long haul.

Everyone knows stocks are for long-term income, so when you are doing your stock investment research and planning your portfolio, consider a few things:

1.) How old are you? The older you get, the less your time window is to endeavor in long-term, risky investments. If you are younger, you have plenty of time to withstand the ups and downs that are characteristic of stocks/stock funds.

2.) What are your goals? When doing your stock investment research, this is probably one of the most important tips you can consider. A lot of people make the mistake of planning incorrectly for an expense. They want a trip to Europe and think they can score the cash quickly by dumping it into the stock market. This is a high risk move and chances are, it won't work. Most people should invest in stocks or stock funds only if they have a long-term goal (I want to buy a house 10 years from now). If your goals are more short-term, pick something safer like a money market or bond. These can yield a moderate income in a few years (3-5) and are much safer for your money.

Overall, in your stock investment research, it's best to remember one thing: you cannot beat the market. So, therefore - the best way to go is with something appropriate considering the points mentioned above.
