Put/Call Ratio Charts
Attached is the put/call ratio charts versus the S&P 500, which shows the combined ratio of all Put/Call options ($SPX:$CPC), as well as the separated Put/Call options between the index options ($SPX:$CPI) which are mostly associated with professional traders and the equity options ($SPX:$CPE) which are mostly associated with retail traders.
Note the divergence between the whats' been happening in the index options over the last few months compared to the equity options. As the professional traders have clearly been getting more bearish while the retail traders have continued to buy the equity options. So something to be aware of at least.
