Definition of 'Consumables'

Investopedia explains 'Consumables'
Stocks of companies that make consumables are considered to be relative safe harbors for equity investors when the economy shows signs of weakness. The reasoning is simple: people will always need to purchase groceries, clothes and gas no matter what is going on in the broad economy.
Many of the items measured in the basket of goods used to calculate the Consumer Price Index (CPI) are consumables; inflation in these items is closely watched because it can lower the discretionary income people have to spend on items such as cars, vacations and entertainment.
