He made a fortune through stockjobbing during the market boom.
Stockjobbing → The word is formed from 'stock' (from Middle English *stoc*, meaning a supply or store) and 'jobbing' (from the verb 'job', meaning to do small pieces of work). The term refers to the practice of buying and selling stocks for short-term profit, essentially doing small transactions in the stock market.
Think of 'stock' as a supply and 'jobbing' as doing small tasks — stockjobbing means engaging in small transactions in the stock market.
