2. Study future earning
3. Study price movement of last 2-3 days. If it is appreciated more than 20%, then it is safe to wait and see how the stock is behave
4. Study the price movement chart. Check whether it is building a price base or in declining trend. If it is in a price base and has not move from 2-3 months it is safe to enter at this level.
Few Example
MBSL (building a base below 50), SEYB-X (attractive compared to SEYB-N, and have a build below 50)
RHL, just started the next move from base below 70
Good Luck !
