Which of the following best describes 'end of day' (EOD) data?

The term 'end of day' (EOD) data specifically refers to information that is gathered at the conclusion of the trading day, capturing the final prices and volumes for securities. This data provides a snapshot of the market's performance and is essential for various analyses, including performance tracking and trend analysis. EOD data allows investors and traders to assess the closing market conditions, which aids in making informed decisions for future trading activities.

The other options do not accurately capture the essence of EOD data. For instance, data accumulated over several months focuses on a longer time frame, which contradicts the specific time frame that 'end of day' data represents. Projected future prices are inherently speculative and not based on the finalized trading information characteristic of EOD data. Lastly, data collected at the beginning of the trading day would pertain to opening prices and is not indicative of EOD conditions, which only reflect the status at the market's close.
