Each individual have their skill level doing what they feel best for them. There isn't right way or wrong way when you decide to buy/sell the stock because nobody able to time the market. Investors think they have an investment strategy where investors buy and sell stocks based on expected price fluctuations. If investors can correctly guess when the market will go up and down then they are not here trading the OCT stock. They be super wealthy corresponding investments to turn that market move into profit.
Unlike many other here. I don't have the ability to time the market. The only thing I know how to do is study the company fundamental. I make my investment base on that. I believes NSPX will produce 6 to 7 figure income for me therefore, I am willing to give a longer time for long-term gain. Trading and investing both involve seeking profit in the stock market, but they pursue that goal in different ways. IMHO:))
