Before buying do some research to know the company, industry, potential growth blab blab blab and there is no best time. Investment is a a gamble. If there is a best time for Sure Win there will be no more people working. Sometimes Luck plays a part in investment.
Selling is no brainer.  When it reaches your target profit, sell and run. Important to note can't be greedy as it can end up either way-earn more or lose big.
Happy investing/gambling .

My dad went through hardship growing up during war time and having to hide in Malaysia and China.  Being illeriate, he have to try everything to survive. He taught me everything can try as long do not die. If fail, learn to give up and escape fast. If doing OK, quickly innovate to be better.
Putting this same theory to trading. If the stock is wrong choice, cut cost, bear the mistake and Run. If share is going upwards, enjoy the blissful but quick look for next share to invest. in short, do not stay stagnant. always be vigilant and active.
Wishing all Fathers a Happy Fathers Day this Sunday.  Being Happy, everyday can be Happy Fathers Day ....
