Shelf Life

Shelf Life - The length of time that a given item, product, service, stock, investment can be or ‘remain in a selling/sell-able condition’ on a retailer's shelf, or making profit/return sense in the marketplace. Similar to expiry dates or  “use by,” “best by” or “best if used by” type descriptive properties referring specifically to the duration and time an item will still be healthy, safe and remain fresh. Purchasing assets, items or investing in instruments beyond these shelf life parameters are not recommended. It is in fact a good metric on how long something will last, be good, but also that they will eventually start declining, or go really bad (south, decrease), in value and return, after a certain time.
