Thursday Good day to short vega and theta means to say that its a good time to create a debit spread? and exit by friday EOD?
yes rise in vix rise in premium but why means vix is non directional index na... so if you get caught on a wrong side so my 1st question?

A vertical debit/credit spread has a low theta and vega.
A simpler statement would have been Thursday is a good day to short options. It was an incorrect statement to say short theta.
See, by option pricing formula, option value by Friday EOD will not include theta decay for weekends. So for decaying the option value, IVs are reduced which is reflected in VIX. That is why I say short vega.
We can get caught on the wrong side, however, you will observe that this is a logical strategy, backed by historical data. If we are clued in with the workings of IV, we will be more often than not on the right side. Given all things equal, which day will I consider for shorting options, my answer is Thursday.
