There’s a midpoint support at 13.09 that we can bottom-fish with a 13.11 bid for 200 shares, stop 13.06. If the stop is hit, look for the selling to continue to 12.15. If the stock gets within three cents of that price, buy four August 12 calls (SLVHL), good through Monday.  If you want to park a limit order with your broker, a price of 0.70 for the calls would be a decent buy.  The snapshot of my option calculator (see inset) shows how I arrived at a price for the options. It may come in on the low side, since call option often pick up “juice,” or volatility, when a stock falls (even as premium levels drop in absolute terms). ______ UPDATE: The stock, which rarely fails to open on a gap, gapped down through the 13.09 support, negating our trade.  However, the play at 12.15 can still be attempted, since that Hidden Pivot has become our new minimum downside target.  Make the order good through Friday, and lower the bid for the calls to 0.60.  _______ FURTHER UPDATE (July 21):  SLV made a key low at 12.27, 12 cents above our target, on July 13, so we took no action. The stock subsequently rallied as high as 13.53 a week later.
