The Oxo company manufactures beef stock cubes, among other products. There have been several Oxo puns mentioning the “stock” market.
   
“Retweeting @andrewsayer: I see the price of Oxo cubes has shot up again. The stock market’s gone crazy” was posted on Twitter on October 23, 2008.
       
“Do you know where you can get chicken broth in bulk? The stock market,” “The only stock options I have are chicken and beef,” “I started investing in stocks: beef, chicken, and vegetable. One day, I hope to be a bouillonaire” and “I went to the store to buy chicken broth, but they said they were out of stock” are related “stock” jokes.
   
           
Wikipedia: Oxo (food)
Oxo is a brand of food products, including stock cubes, herbs and spices, dried gravy, and yeast extract. The original product was the beef stock cube, but Oxo now also markets chicken and other flavour cubes, e.g. Chinese Recipe and Indian Recipe. The cubes are broken up and used as flavouring in meals or gravy or dissolved into boiling water.

If you opened a market stall selling only oxo cubes and gravy granules, then when you meet attractive women in bars, you could tell them that you are big on the ‘stock market’
