Here are some action that you can take
1. Dont overdiversify. If you buy 20 shares, then even if one of them gives great profit, your total profit will be very small. So have about 10 shares.
2. Put equal amount in each of these 10 shares. This way you will have a balanced portfolio. So if you are having 3 lakhs to invest, then put 30,000 each in 10 scrips.
3. Have a stop loss for each investment. If the stop loss is hit then sell immediately.
4. Trade with the trend of the market. Even if you buy shares of company with the best fundamentals, but the general trend in the share market is bearish, then you will only make losses.
5. Lot of good practical information about trading strategy over the internet. Read it up, especially about technical analysis.
