still sidelines for now. i bid on COST dec18 puts at the open, but too low and didn't fill. not gonna chase. but might add some puts if a decent rally stalls at high price.
logic is that COST earnings at down 7% while COST was at all-time-highs enjoying at 31 P/E ratio.
with membership growth declining, that shiny P/E ratio will also drop. so we may see a 10-15% drop in COST over the next couple weeks.
