Having good strategies or plans will help you earn money in the stock market. But here are some great strategies that can maximize your profit.
Basics of Investing
Investing: An investment operation is one in which, upon thorough analysis, promises safety of principal and a satisfactory return”. - Benjamin Graham
Thus, the secret to investment riches is to invest when: Price << Value. This is call Margin of Safety

“A margin of safety is achieved when securities are purchased at prices sufficiently below underlying value to allow for human error, bad luck, or extreme volatility in a complex, unpredictable and rapidly changing world ” - Seth Klarmam
"Prices tend to fluctuate more than values. Therein lies opportunity”. - Joel Greenblatt
Buy low, sell high( simple idea of margin of safety).

Compounding
A thought experiment:
On day 1 you are given a penny. The penny goes up in value 100% every day when invested. You want to maximize your money.
• Which path do you take for the next 30 days?
a) leave the penny invested, withdraw the interest (one penny) every day $0.31
b) take $100,000 in cash with no investments $100,000
c) leave the penny & interest in place for all 30 days $5,368,709
Diversification– Removes nearly all idiosyncratic risk, thus minimizes total risk:
Can be achieved with a portfolio of 20-30 stocks;
Holding stocks that is not related; so if one drops it doesn't affect your portfolio as a whole.
