@Da_MoLe Why do you think you are helping company X when you buy its shares? The money you spent did not go to the company.
The idea that you only make a loss when you sell is a truism but at the same time can bite you if you are really investing. There are many good reasons to take losses quickly. Some shares never ever ‚recover‘ or take tens of years to do so. And there is inflation to consider. As an example, Look at this screenshot from Google Finance of a share you own:
If you had (for example bought these in Nov 2007) you would have been sitting on a wasted asset for the past 15 years with no sign at all that it will ever recover to that lofty high. That brings us to another point about shares - forget about the past. What you bought at is a sunk cost. You have to look at shares in terms of the future. The call you need to make is: “Are the business prospects improving or not?”. You need to have a clear handle on what “improving” means.
I recommend as @rehpot suggests to consider not investing in single stock shares unless you have done your research. Consider employing a passive investing strategy. Look at this Topic Passive Investors - ETF Portfolio Discussion and read this answer How to diversify - #115 by bitflip.
Good luck with your investment journey.
