- randomcarbloke 5y agoit's the library, not the models. and no.
- boppo1 5y agoI always seem to hear from finance people that asset modeling is done in excel. Or are we talking modeling statistical relationships between assets? The fundamentals-based valuation and statistical arbitrage approaches are so different, I wonder how they get reconciled into an overall profitable strategy. Or are fundamental valuations strictly used for the department and statistical relationships for the active trading department?
- Ntrails 5y agoTrading on the stock market is a negative sum game (you pay fees to play, so the sum of all outcomes is negative). Tooling is an edge, giving it away is not nothing. Typically data is also an edge. Realistically though, they're small edges and I guess GS believes the upside is worth it

I can imagine: - easier to hire/train, candidates will compete by learning the internal library before joining - community bugfixes/feature contributions, although I can't imagine there's anyone close to being as on top of this as the GS dev team, given the GS work-life-balance
