Omnium is a term used in various contexts, but it is most commonly associated with the world of cycling. In competitive cycling, an omnium is a multi-race event that includes several different track cycling disciplines. Cyclists accumulate points based on their performance in each race, and the rider with the highest total points at the end of the event is declared the winner. In finance, "omnium" can refer to a type of investment fund that pools resources from multiple investors to invest in a diverse range of assets. This approach allows for risk diversification and can provide investors with access to a broader market than they might achieve individually.
