Thanks for the response. I do notice very similar premiums on the June call options. However, I still do not understand why the premiums are so different for January. I do not mind buying the call options on the GLD with a higher premium as long as I can sell them with a similar higher...
Can anyone tell me why there is such a difference between the price of a call option for $1600 gold January expiry on the GLD ETF and the Comex? It appears to be around $50/contract for the Comex and $200/contract equivalent on the GLD.
