Golden Data July 19 news, Anthony Cohen, a global Options and Futures broker at Market Securities, said that Microsoft's technical malfunction is bad news for the market. He said: "This interruption may have a serious impact on current prices, as derivatives professionals, index and interest rate market makers are all affected by this situation, which means that the liquidity of Options is drying up, which is likely to affect their pricing ability, as well as their ability to hedge existing positions, further dropping liquidity in the summer market."
