if you are going to continue to invest in shares you need to do some work and not ask random strangers on social media. There are lots of free newsletters around. Start reading some of them.

Often the drops are because of something happening in the rest of the world e.g. Trump getting aggro towards China because of Hong Kong, Have a look at what the ASX is doing - sometimes it’s just the whole market is falling, or bad retail figures. The more info you have the less bewildering it will be.

you can even go and read the companies releases and have a look at half year and yearly figures and try and understand what the company does and where it is different,

if you are just randomly buying a share, then you may as well go to the Casino and put all your money on black....
