Options Expirations Provide Clues Into Equities' Intra-Month Cycles

US indices NASDAQ 100 and S&P 500 made new all-time highs on Monday, gaining 1.46% and 0.85% on the day. Last week's drawdown was bought back as quickly as it was in the last several months.
 
The daily charts of the S&P 500 clearly show how the American market indices have been falling over the last year by the expiration date of the monthly options (third Friday of the month). In the meantime, explanations for market movements due to fears of increased illness or a sell-off are falling by the wayside.
