Dividend Chaser Sell Singtel Stock

Stock market unstable lately. I sell away my singtel share today at a small loss. Singtel is in uptrend today from 3.16 to a high of 3.25. I sold at 3.23 before it hit 3.24. Singtel has declared dividends of 0.68 with ex-dividend date at 27Dec. I have no confidence that the share will hit 3.30 end of this year that is why I am letting go first.
