Answer:
The sale in this situation is a trading.
Step-by-step explanation:
The buying and selling of stocks for short periods of time is termed trading. This is usually dependent on the stock prices but also on the holding period which goes from 3days to 364days. This period starts as from 3 days because of the 3-day settlement rule which requires that the brokerage firm clears all payments within these days, either for stock bought or sold.
Any stock held beyong 364 days becomes long term gain and such sale is considered investing.
