"If your holding price is say 15p and you own 10,000 shares, your capital at risk is £1,500. If you are permitted to buy in the ratio 1:100 at 50p for instance, you have the RIGHT to buy a further 1,000 shares at 50p. So if you took the offer up, shell out £500, your capital invested rises to £2,000"
But if the SP is less than 50p at the time of the announcement of the rights issue, it would be irrational to take up the offer to buy shares at 50p.
