up until Wednesday afternoon, OSTK has seen daily bullish trading up to ~1030. at that point, buyers seen to abandon the spread, ignore the ask, and let the trading fall carelessly to the bid, resulting in a slow bleed for the rest of the day, often erasing most of the early gains, and even going negative.
last Friday 1f19 also saw a shake down to $16.25ish which played well for that's days $17 & 17.50 OpEx.
thought? volume is very inconsistent, ill-funded, and narrow. I don't believe there is any deliberate shorting aimed at price points on the chart. there is an accumulation of shorts simply trading this passive-aggressive opportunity.
why...while OSTK is being noticed, there is a wide family of equities moving in the blockchain sector, and a similar broad base to accept investment. so OSTKs p-a market behavior won't find stability until blockchain monies grow within mutual/ETFs.
The takeaway for now should be that pops in OSTK can still be traded with confidence. closing calls for profits. rolling those profits forward in the calendar to exploit anticipated good news, and reinvesting the core option equity back into calls as the price spike peters out, and call prices shrink back down.
