Final answer:
The S&P 500 has a broader index than the DJIA because it includes a larger number of companies in its index.
Step-by-step explanation:
True. The S&P 500 has a broader index than the DJIA. The S&P 500 index is based on the weighted average market capitalization of 500 large U.S. firms, representing the economy as a whole. On the other hand, the DJIA is a price-weighted average of 30 industrial stocks on the New York Stock Exchange. So, the S&P 500 includes a larger number of companies in its index, making it broader than the DJIA.
