This week has been a roller coaster ride for investors. A weaker than expected US jobs number and an interest rate move by Japan’s central bank made markets topsy turvy.

Or could we see worse? Dan Chang, an investment specialist from PhillipCapital weighs in and shares his views on the current volatility and the Singapore market.
