An ETF that holds no shares adds nothing to the portfolio's side. For an ETF read from its SEC filings, a holding the filing lists on a market abroad matches only the same holding abroad.","share_of_candidate":"The part of the candidate's weight in companies the portfolio also holds, each counted at the candidate's own weight. It is never below the overlap, which counts the smaller of the two weights.","correlation":"Pearson's correlation between the candidate's weekly returns and the portfolio's, on the weeks both have: at most the 156 the files carry, at least 52. The portfolio's weekly return is the return of its ETFs at their weights, counting every ETF with at least 52 weekly returns here, whatever it holds. A weekly return is a weekly total return, from the last close of one week to the last close of the next, with dividends reinvested, as in the fund files. The weeks end on Fridays, or on the Thursday when the exchange is shut that Friday, and the last one ends on the files' last close.","down_weeks":"The same correlation on the weeks the portfolio's return was below zero, when there are at least 20.","mega_cap_tech":{"rule":"A fixed list, the one every fund file's breakdown and every ETF page count: Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta Platforms, Broadcom and Tesla, every listed class of each.","companies":[{"name":"Apple","tickers":["AAPL"]},{"name":"Microsoft","tickers":["MSFT"]},{"name":"Nvidia","tickers":["NVDA"]},{"name":"Alphabet","tickers":["GOOGL","GOOG"]},{"name":"Amazon","tickers":["AMZN"]},{"name":"Meta Platforms","tickers":["META"]},{"name":"Broadcom","tickers":["AVGO"]},{"name":"Tesla","tickers":["TSLA"]}]},"sectors":"Each ETF's breakdown, as its fund file and ETF page give it.
