Let’s start building a calendar spread again, legging into the buy side first. I’d like to start with March 15 calls, but since there are none, we’ll work on the December 12.5s (SLWLV). Bid 0.50 for four, 0.45 for six more, and 0.40 for another six, all good-till-canceled.  Once we lay in our inventory, we’ll look to short September or October 12.5 calls against it. _____ UPDATE (1:22 p.m.): The calls were un-buyable at our price earlier in the session because Silver Wheaton began the day with a wicked short-squeeze. However, the stock has since retraced most of this feint, allowing more than 500 December 12.50 calls to trade at the top of our ladder. Assuming four calls bought for 0.50, we are now bidding 0.45 for six more and 0.40 for another six, both good-till-canceled. _______ FURTHER UPDATE (August 26, 12:12 p.m.):  The December 12.50 calls traded down to 0.39 today, so we are filled on the order. We hold 16 calls with an average cost of 0.45.  Do nothing further for now.
