Means.... ?
It's a small series, less than 4 weeks, so the options will suffer time decay quicker than other months. Also, the market will be closed for 2 days till Monday, but the clock ticks on. Observe the behaviour of the options on the Friday of the 2nd and 3rd weeks of the series, you may see them generally going down in value for both PE and CE. But this is the first week of the series, the big traders seem to be taking position on both the sides, so the option value is not going down.
