What is Swing Trading in Short and Simple way?

 In a short and simple word, swing trading is a trading style based on your stock holding period.

Still confused ?.. excellent.

Let Understand it by an example:
            

            You might have heard about Long-Term Investments and Short-Term Investments. 

            Then, which investment will be considered as Long-term and which will be short-term.

            These are defined by the time period of your holding in a particular stock or investment instrument. If you buy a stock and hold it for more than a year then it will consider as a long-term investment. If you buy a stock and hold it for a year or less than a year, it will consider as a Short-term investment.

Swing trading is also a short-term investment, but its holding time period is very small like 2 days to 3 - 4 weeks or a couple of months.

Again a question arises. Then why it is called trading instead of short-term investment?

Hmm...,  You can call it if you want, but the reason behind calling it "Trading" is because of Monthly Derivative Contract Trading in OPTIONS & FUTURES market segment is almost have the same duration or another reason is your intention while buying the stock. You are not planning to hold it for long instead of that you want to take the advantage of certain price movements and book the targeted profit as soon as possible.
