hi, underage here, know nothing
i wanna ask if i buy 10 shares but tomolo drop 20 shares, does it mean i need to pay another 10 shares to cover up the loss
Your concept of buying shares on the stock market is wrong first and foremost.
The number of shares on the market is fixed or constant. Meaning if there is 1000 shares in the market held by different people, it will stay that way.
When you buy a share for a price let's say RM1.00 for 1 share from someone else.
You will pay RM10.00 for 10 shares to that person.
If the price tomorrow drops to RM0.90 a share. You do not need to top up. You still hold the 10 shares you bought, just that it's worth on the market is now lower or RM9.00.
There is a very good guide in
Investopedia for stock market newbies, explaining the concept of the stock market. You can learn a lot from doing the tutorial. Much more than what you can expect from short answers here.
