Good books/websites for learning about Options pricing (e.g. S&P Puts)

[thowed]

So I mainly research & select funds, but I want to expand the old circle of competence in this environment & have the option of buying Puts etc. for protection.

 

I passed CFA Level 1 ages ago & can't remember much about the Options stuff there.  Should I just re-read my notes?  Or is there a good book/website for learning stuff that explains it simply for busy people, so I don't buy outrageously overpriced Puts etc.

 

Many thanks for your help.

Not sure whether or not this will be helpful for you, but the most important concept to get comfortable with is implied volatility, which is basically a shorthand way of comparing the option market's expectation for the size of the range of future outcomes for stock prices. Once you have a basic understanding of what it means, you can start comparing implied volatilities among different options the same way folks compare stocks on their favorite valuation ratios.
