dmc, the ex-dividend date is usually 2 days BEFORE the date of record. Some stock divys are one day after the date of record.
The ex-dividend date is set 2 days before saying that those that purchase shares closer than 2 days prior to the record date are not eligible for dividends.
However, all shareholders on the date of records (not purchasing within the ex-divy) period get the dividend.
To my knowledge, I have never seen an ex-dividend date after the date of record. In the case of CMKX, I do believe the ex-dividend date was 2 days prior to the date of record.
