Hi, I’m a little confused about how to sell specific shares in a single company.
For example, if I bought 1 share of a company at £1 and then bought another share a few months later at £5.
I wait 1 year and the stock goes up to £10.
I know own a share with a gain of £9 and a share with a gain of £4.
If I want to sell one of those shares, how do I know which one I’m selling?
