Normally when someone asks a question, they either;
A) Don't know about it and wants to know more
B) Not sure about it and want to ask others to see if its correct generally
C) Already know about it but just want to see if others are similiar

For option A, you're looking for advice for what you don't know and want to know more.

For B, you have an idea what you know, but not confident if your theory or assumption is correct.

For C, you just wna to know what others know and will try to brag or discuss maturely about the differences.

So which one are you?

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.
