To give you an example that this actually can be bulish: look at todayFeb 20 expiry put trading:at 9.49am
someone sold 4500 $firstname.lastname@example.org and purchased same amount 4500 $85 puts @1.59 for a total credit of $1.3 Millon. Similar trade in April 17put option chain: 75/82.50 9000 contracts each strike price at exactly same time for $1.73 Million credit. It looks bullish to me..
It's a matter of perspective. Most likely someone is selling puts for a credit (premium collected) or it could be bull put credit spread. That would signify that the bottom is close. Big players don't like to be assigned stock so most likely they will defend the price. That's my perspective..: ;) GL
