A product that I've wanted for a long time is "broad market index fund , minus the individual stocks I am overweight in due to current or previous employment equity" (e.g. VTSAX - MSFT, GOOG/GOOGL), any chance you can handle this today/build it out in the near future? Sounds like you might be able to handle this already?
Yes we can handle this already. You can customize our broad market indexes by removing or lowering the weights of specific stocks (or sectors although you asked about stocks).
From a functional perspective, you can already do that using options, look at market neutral strategies for an example of how to construct a position like this. From a practical point of view, I doubt you want to get your nose into complex financial instruments just for that.
To your point, I _very much do not_ want to stick my nose into complex financial tools, hence my desire to use a more simple tool to get the exact value of "give me the thing I generally want, minus the one or two things I don't." Sounds like this is one option for doing so!
I'd argue it's a good idea to consider one's current job-industry as an aspect of diversification even without having large RSUs/stocks/options.
Better to have either a market downturn you can ride out while working, or chronic unemployment while your investments are strong, instead of the double-whammy of long-term unemployment and a big portfolio downturn at the same time.
