A stock market index made up of 600 small-cap U.S. companies chosen to represent the performance of smaller publicly traded firms.

The S&P MidCap 400 is a group of 400 companies that are smaller than the big, well-known corporations but larger than tiny startups. It helps investors see how medium-sized companies are performing in the stock market, acting like a barometer for this middle-sized group of businesses.

reit financial

"Whitestone REIT (NYSE: WSR)"

A real estate investment trust (REIT) is a company that owns, operates, or finances income-producing real estate, like shopping centers, apartments, or office buildings. For investors, REITs offer a way to invest in real estate without having to buy property directly, often providing regular income through dividends. They function like a mutual fund for real estate, making it easier for people to add property investments to their portfolio.

"Ticker | GICS Sector"

GICS sector is one of the major industry groupings from the Global Industry Classification Standard, a system that sorts companies into consistent categories (like Technology or Health Care) based on the primary business they do. Investors use these sectors like folders in a filing cabinet to compare companies, build diversified portfolios, and track how whole parts of the market are performing rather than focusing on single stocks.
