If you’re going to treat buying QQQ puts as a 0DTE or 1DTE day lottery ticket, you should at least know how often the market gives you a winning number.
We analyzed over 3,000 trading days of QQQ data to answer a simple question:
How often does a given period include at least one “down day”?
A down day is defined as a daily drop from the previous close to that day’s intraday low.
Then, for each period length, we measured how often at least one such day appeared.
