relative-strength

IBD Style Relative Strength Percentile Ranking of Stocks (i.e. 0-100 Score).
I also made a TradingView indicator, but it cannot give you the percentile ranking, it just shows you the Relative Strength: https://www.tradingview.com/script/SHE1xOMC-Relative-Strength-IBD-Style/

Daily Generated Outputs

Stocks: https://github.com/skyte/rs-log/blob/main/output/rs_stocks.csv
Industries: https://github.com/skyte/rs-log/blob/main/output/rs_industries.csv

Known Issues

Unfortunately the close prices loaded from the price history API are not always split adjusted. So if a stock had a split recently there is a chance the relative strength value will be wrong...

Calculation

Yearly performance of stock (most recent quarter is weighted double) divided by yearly performance of reference index (SPY by default).

Considered Stocks

Tickers from ftp://ftp.nasdaqtrader.com/symboldirectory/nasdaqtraded.txt disregarding ETFs and all stocks where the industry and sector information couldn't be retrieved from yahoo finance.
