What Does Cum Dividend Mean?

Cum dividend means "with dividend." A stock trades cum-dividend up until the ex-dividend date. On or after this point, the stock trades without its dividend rights.

Stocks are cum dividend until they go ex. Holders of the share on the ex date are due to receive the dividend. Once the dividend has been paid the shares go "cum" again.
