There are thousands of small shareholders who have held them for years, and whose income has been decimated,
What they weren't told when they bought them, but which now seems to be standard practice when 'selling' investments (a legal requirement now?) is that 'The value of your shares can go up or down'. Obviously dividends can follow the same principle.
There is absolutely no safe place for your money to be invested apart from in an interest paying bank account, which is legally obliged to guarantee that you won't lose your principle, up to £85,000, in the event of any 'downs,' and, in government bonds or savings accounts which are absolutely guaranteed to be 'safe' as the government will not renege on its debts.
Expecting share values and dividends to remain constant, or continually rise is unrealistic. Investment is always a lottery. If the market bombs, you lose your money.
