3 terms

environmental, social and governance (esg) financial

"based on long-term environmental, social and governance (ESG) criteria."

Environmental, social and governance (ESG) refers to a set of standards that evaluate how a company manages its impact on the environment, treats people and communities, and oversees its leadership and operations. Investors use ESG factors to identify companies that are responsible, sustainable, and better positioned for long-term success, much like choosing a vehicle that is both eco-friendly, safe, and well-maintained.

float-adjusted market capitalization financial

"The DJ BIC are float-adjusted market capitalization weighted indices that track"

Float-adjusted market capitalization is the total market value of a company’s shares that are freely available for public trading, excluding shares held by insiders, governments, or other long-term locked-up holders. Investors care because it shows the portion of a company that can actually be bought or sold on the market — like valuing only the slices of a pie you’re allowed to trade — which affects liquidity, price impact of trades, and how weightings are set in many investment indexes.

indices financial

"float-adjusted market capitalization weighted indices that track equity markets"

Indices are measurements that track the combined performance of a selected group of stocks or other financial assets, acting like a thermometer for a segment of the market. They matter to investors because they reveal broad market trends, provide a benchmark to judge how individual investments perform, and underpin index-based funds that let people buy wide exposure without choosing single stocks — like buying the score of a whole team instead of one player.
