      Stock market does not always go on uptrend..If it were,everybody would jump into market.As Warren Buffet rightly said: You can not have baby in a month by making nine women pregnant..It is all about timing and how smart you play in market to get in and out..If I were you,I would sell stocks on next week bounce.
