Hey, I am sure someone here can answer your question better than me but I give you my two cents.
As a common folk, I started with £100 in July 2019 and I kept increasing by little amounts each month/week.
There is not a short answer. I would say your expectation of profit should be related to three things :
1)the time you want to keep your investment going before take what you have earn. If you look in a month of a year window, very little. But in 10/20/30 years those 100 pounds if you are lucky may be worth x10 or x100.
- type of strategy or combination of strategies you use (dividend or growth? individual stock or EFTs ? Bond or stock? Any specific sector? Trading, short term investing or long term?
