Happy November. I went through Nasdaq's website - https://www.nasdaq.com/market-activity/dividends - with information on upcoming dividends. I picked out dividends of companies that I'm interested in - whether I already own them or am looking to buy them. The list is sorted by ex-dividend date. If I choose to buy any of these stocks, I will need to buy them before the ex-dividend date.
If I want to received the $1.11 dividend from Clorox, with an ex-dividend date of Tuesday, 11/3, I will need to buy the stock tomorrow, Monday 11/2.
Also note, the current price of the stock is as of Friday, 10/30.
I'll try and update with any purchases I make.
Don't forget to vote on Tuesday if you have not already!
