big-cap

The term 'big-cap' is a modern financial compound, formed in the late 20th century within the context of stock market analysis. It combines the common English adjective 'big', denoting large size or significance, with the clipped form 'cap', derived from 'market capitalization'. Market capitalization itself stems from the Latin 'caput' (head), which evolved to signify the principal sum or capital in finance. Thus, the literal logic of the word is "large head" or "large capital," directly describing a company valued at a large sum in the financial markets. This compound exemplifies the trend in financial jargon to create concise, descriptive terms by blending and shortening existing words.
