Bloomberg: The positioning in equity options was already leaning more and more bullish ahead of the upbeat vaccine news. The headlines confirm the optimistic view towards more reopenings and economic progress, bolstering confidence to bid up equities this morning. Cross checking with put open interest on two liquid ETFs, SPY and QQQ, and also on the S&P 500 shows the number of put contracts are closing in on the fewest since July of last year. Pessimism is abating in options. It seems just a matter of time before that seeps into into cash trading.
