Article mentions rights issues dilute the value of each share of the company. Wikipedia mentions a broader definition of equity dilution is any activity that reduces the per share value of the company.
Anyway, the technicality is not important. Was your point on trying to correct the words I’ve used or that markets view rights issue / equity share capital expansion / other forms of equity dilution separately, hence different valuations may be granted based on equity capital expansion / equity dilution?
