A good time to buy in is within 3 days of the dividend announcement.
Do a little historical dd, track down the announcement dates then compare that to the share prices in that range, you'll see a low.
The run up to the "xdate" many times exceeds the amount of the dividend.
Just keep in mind once the stock has gone xdate, the sp usually tanks by the amount of the promised dividend or lower as people who've qualified for the dividend sell out.
