One ETF's weekly returns, as Find reads them

The files Find reads, public like every file under /api/v1/. candidates.json is the list: its date, its groups, its rule in words, and each ETF of it with its weekly returns, its breakdown or what it holds, and what its file counts for against the limits of an answer. /api/v1/diversify/weekly/{ticker}.json, in lower case, is one ETF's weekly returns and breakdown, for every ETF with at least 52 weekly returns whose last week is the list's, with its own ranking against the list. An answer of have alone is a sort of these measurements by the published rule, the same list for every portfolio: a ranking can be recomputed from these files alone, as Pearson's correlation of w against the portfolio's weekly returns at its weights.
