Someone with a big pocket, for sure a professional, made a huge Gold bullish option bet during the last trading session. The trader purchased 40,000 Mar 2015 GLD or SPDR Gold Trust (ETF) (NYSEARCA:GLD) gold call options. The strike of the call options was $120, which is not very far from the current price of about $117, so the premium paid was huge. Still due to the limited time until March 2015, it’s obvious that the option trade was a bold, directional bet expressing the view that Gold might appreciate up to $130-$135. The amount committed to the trade was $10+ million. If the price of GLD reaches the range $130-$135 before expiration, this pro trader, probably working at a desk in a big bank or a hedge fund, will make between 300% and 600% of his investment or $20-$50 million net profit.
