Vale (VALE): An investor sold 22,556 September 17 calls for $0.20 and bought 30,000 October 18 calls for $0.24, rolling a bullish position forward in time and increasing its size in hope the stock will continue to climb. VALE fell 1.90 percent to $16.49. (See related story )

Coca-Cola (KO): An investor bought 13,200 November 40 calls for $0.36, but sold a large number of shares at the same time. Known as a delta-neutral trade, the strategy will benefit from increased volatility rather than higher share prices. KO fell 0.05 percent to $38.61.

Microsoft (MSFT): More than 21,000 September 35 calls were bought, mostly for $0.06 and $0.07 as investors look for more upside in the software maker. MSFT rose 1.61 percent to $32.91.
