Nope. It’s price weighted. Hence the comment on how dumb it is.

  Sounds like a simple thing to solve if they just let me make a pull request for the function getDJIAValue() or wherever the hell it lives. Based on price is fine -- when splits happen just adjust the weight by the split factor. Are they really that incompetent at coding?

    >Based on price is fine -- when splits happen just adjust the weight by the split factor It's not fine since companies have varying counts of shares, nevermind the stock splits. The proper solution is getSharePrice() * getShareCount(). Which is what most other indeces do.

    It’s not an error in the implementation, the problem lies within the index specification: https://www.spglobal.com/spdji/en/documents/methodologies/methodology-dj-averages.pdf https://www.spglobal.com/spdji/en/documents/methodologies/me...

      So change the specification. Fire the person who hasn't changed it already and schmoozing with beer in a Manhattan high rise, and put an engineer in charge.

        They did, it's called the s&p 500, and it's run by the same company.

        If you change the specification, that’s a new index FFS. It’s like changing the specification for Fahrenheit.

          Oh I'd __love__ to change the specification of Farenheit so that people get confused and stop using it.
