ANSWER:

What this scholar has said is baseless

You can buy and sell on the spot and in a matter of seconds if you wish. 

QUESTION: About stocks trading?I know that no haram,riba & interest.Some situations: I buy stocks and keep them for few hrs and sell them at end of day. If no increase,will sell them next day or after 5-7 days, or in a month till they go up. A scholar said:is it possible to own a stock & become an owner for just a day or two, so that’s gambling. My point is it’s not common, but doesn’t mean it can’t happen.
