comment Individual/casual investors and the bias towards blue-chip stocks?
I said the bias is not limited to individual/casual investors. Institutional investors have a bias toward large caps, as well, for their own reasons. It's the stocks that the market as a whole is biased against that are going to do better.

comment Individual/casual investors and the bias towards blue-chip stocks?
I think Fama and French en.wikipedia.org/wiki/Fama%E2%80%93French_three-factor_model have found evidence for such a bias. Not just individual/casual investors either. Namely they found that small cap outperforms big, and value outperforms growth. (I think it's likely that stocks with high visibility characteristics and "positive skewness" do tend to be growth stocks, though.) Data on the fraction of institutional ownership for stocks is fairly easily obtainable, too.

comment How to generate a random price series with a specified range and correlation with an actual price?
So you wanted to bootstrap your original price series... en.wikipedia.org/wiki/Bootstrapping_%28statistics%29 ...interesting that the answers do that in the frequency domain.

comment Why the interest rate for put-call parity is not constant?
Well here's an exercise for you @Strange one. Buy a call 1000 and sell a covered call 1500. Then buy a put 1500 and sell a secured put 1000. What did that all just cost you net, and what's it going to be worth come expiration time? Can you figure out the interest rate from that?

No. $\frac D {strike}$ is different for every strike, not $D$ itself. Whatever the market expects dividends to be, that's what they're expected to be, regardless of options.

@John Dividend is the same across the board, but of course "dividend/strike price" is higher for lower strike price.

@John it still doesn't matter whether or not the dividend yield is higher for a lower stock price.

@John Dividends have nothing to do with strike price.
