Investorpedia.com also states the Ex is TWO days before date of record. These terms confuse a lot of traders.
It's really semantics.Take the record date, count back two days but don't include the record date.Or include the record date and it's three days.I do the former. Find the record date. Count back two days not including the record date, that is ex div. So, if it's a Friday, count back Thursday and Wednesday, two days. Wednesday is ex-div.If you buy on Tuesday you get the distribution or dividend.Once, you get used to it, it's easy.
