there are various ways to quantify risk and 'blue-chipness' or what categorizations you want. The secret is to find and build what works for you. There is work involved in learning more about yourself and what is acceptable for you. For risk, you might look at volatility (many different measures for volatility), or you might look at financials and historic performance of financials. So many different ways to quantify things. The trick is to build what works for you. No cookie cutter here. You might get ppl say that you should use X measurement but then someone will say you should use Y. which do you use? they both work for each individual. So... test, reflect, refine, test again...If by proper categorization as an essentiality to risk management you are referring to the realized volatility of the underlying, I agree 100% and would like to hear you out more in this regard as this is a major question to me. To illustrate;
How do you equalize risk between trading weeklies on an index like SPY, that has much lower realized volatility than, say, NFLX, which has high realized volatility? Because a move on SPY has the same weight dollar-for-dollar as a move on NFLX in regards to delta. The complication is, to your point on categorization, that a dollar move on SPY carries far more risk than a dollar move on NFLX. Perhaps you would use gamma?

jk, but you get the point.
