Axis charter
Positive (+) means FAVORITES win and upsets fail across major sports competitions: the market's subject is the consensus favorite for its event (the single most-likely winner of the tournament/series/award at scoring time — judged by current price relative to rivals and common knowledge) and YES = that favorite winning, sign +1. If the market's subject is a NON-favorite whose win would be an upset, YES = upset, sign -1. The index reads high when chalk is priced to prevail everywhere and low when chaos is priced in. Only outright winner/champion markets for prominent competitions qualify (World Cup, Champions League, NBA/NFL/MLB titles, majors); single regular-season games are low magnitude. Cluster legs by competition.
