為什麼新年前要放晒股票

Because Chinese hoilday stock market is not open (three trading days in Hong Kong), and outside market like New York, Japan dont have holidays (business as usual), that's why most people will sell out the stock first for this kind of long holiday afraid will affected by outside market.
Remarks: China Market is not doing business for more than 3 trading days, almost have 7 trading days .

其實真係買大細, 過年後雖然開紅盤機會大, 但唔係100%, 係而家既波動市, 有賺既可以先離場, 開心過新年, 優質長線或未到目標價可留住先, 新年後再部署.

noman is correct.
In these few years, the stock market is raised at the first day of the lunar year.
This year, expect to be even better as China stock market is full of fundings.

答案剛好相反，依以往的歷史，新年開紅盤(股市上升)的機會有七成以上。在中國人的心理，過年時要一些好意頭的事，所以當沒有特別消息，都喜歡托高過市，希望將好意頭帶至全年。
而近年很多人都會偷步，在每年完結前的一個成交日，亦都會入貨，使市上升。昨日大跌，今日微升，明天不知會升或跌，但我估星期五或明年(舊歷年)開市都應會上升，你若對市沒有信心，想出貨可以在年初四。
若初四時，欲升無力，才應考慮全面出貨。
我本人認為個市必定會上22000點或以上，所以不用太担心。

問者觀念錯誤。
十年有七年以上，股民及基金都會買入股票，等開紅盤，可來會新年前清貨。
答者亦依問題亂答。
