This is the at 0.52, saying that for every put there are 2 calls around. It is the lowest level since many years, meaning that
1- there is a lot of optimism in the market (usually followed by a drop)
2- investors want to ride this rally until it lasts, and for this goal it is better to have options that just the underlying.
Of course the TF is weekly and we are just in the first day of he week so the data can change, but it is the sameon the daily also. I used the weekly TF just to show you more data in the past.
Keep your eyes open
