You can to it simply like this. It is not that commonly known but you can make UPDATE on a SELECT

UPDATE 
    (SELECT 
        company, direction, TYPE, YEAR, MONTH, VALUE, 
        RANK() OVER (PARTITION BY direction, TYPE, YEAR, MONTH ORDER BY VALUE DESC) AS NEW_RANK
    FROM table1) a
SET RANK = NEW_RANK;
