I noticed that the options on BNO have maintained a positive attitude after the April developments. Looking at the data, the put-call ratio has dropped significantly - from 0.24 to 0.17 - which generally means that investors are more optimistic about crude oil. When you see this kind of movement in options, it usually indicates that sentiment is turning upward. Also interesting because some big names in the energy sector like ExxonMobil, Valero, and ConocoPhillips are showing interesting setups in this context. If you're looking at options on BNO, these movements in the put-call ratio deserve attention - when the ratio drops like this, it's often a signal that traders are becoming more bullish on the market.
