I happened to inherit the shares of my late Uncle who was a Reverend. The irony is that the shares are worth only a paltry sum and in one month, they earn a dividend of 1$ and 20 cents. If I want to transfer those shares into my name, I would be spending ten times more than that amount.
As an idiom Beggar shares defers to shares whose value is equivalent to that giving alms and who’s value less than the invested money and whose value does not increase with the passage of time.
Yes Shares can be Bullish and Bearish but Shares can also be Beggarish.
Example: The shares which my late Uncle bequeathed to me are Beggars.
