I've basically worn out my welcome at Google searching for any sort of free API or data set that maps stock ticker to sector/industry. Yes, I know that individual sites like Yahoo Finance display this information on a per-ticker basis, but I'm trying to pull down a “complete” data set that I can store locally and use without resorting to screen scraping individual pages. Ideally, there would be an easy way to refresh that data over time (e.g., monthly). I would think this would be relatively simple, but I can't seem to find this, other than scraping. Some of the obvious places (e.g., SEC EDGAR) don't seem to have this data, which surprised me. Any ideas? Am I overlooking something obvious? I'm OK doing some programming and synthesizing the result from multiple sources, if that's required. Thanks in advance.
