Key Terms

average daily volume (ADV), multi-listed options, trading volume, revenue per contract, +1 more

5 terms

average daily volume (ADV) technical

"MIAX Exchange Group reached a record average daily volume (ADV) of 11.1 million..."

Average daily volume (ADV) is the typical number of shares or contracts traded in a security each trading day, calculated by averaging activity over a set recent period. It tells investors how easily a position can be bought or sold—like measuring foot traffic in a market stall: higher ADV means more buyers and sellers and usually smaller price swings when trades occur, while low ADV can lead to bigger price moves and trading difficulty.

multi-listed options financial

"MIAX Exchange Group executed a record 2.4 billion multi-listed options contracts..."

Options that are listed and traded on more than one exchange at the same time; think of the same airline ticket being sold at several different ticket counters. For investors, multi-listed options matter because they usually increase the pool of buyers and sellers, which can make it easier to buy or sell a contract quickly and can lead to tighter bid‑ask spreads and more reliable pricing. They can also create short windows for traders to exploit small price differences between venues.

trading volume financial

"Summary statistics including trading volume and market share by business segment..."

Trading volume is the total number of shares, units, or contracts that are bought and sold within a specific period. It indicates how active or busy a market is, much like how many customers visit a store in a day. Higher trading volume generally suggests greater interest and can influence the price movements of a financial asset.

View in glossary

revenue per contract financial

"rolling three-month average revenue per contract and capture rates are available..."

Revenue per contract is the average amount of money a company earns from each customer agreement or service contract over a defined period. Investors use it like an “average ticket price” to judge whether a company is charging enough, keeping costs under control, and growing profit per deal; rising revenue per contract usually signals stronger pricing power or higher-value customers, while declines can warn of discounting or weaker demand.

capture rates financial

"rolling three-month average revenue per contract and capture rates are available..."

Capture rates measure the proportion of a defined pool of opportunities that a company, product or program successfully secures or converts — for example, the share of potential customers won, prescriptions written out of eligible patients, or users who adopt a new service. Investors watch capture rates because they show how well a business turns potential demand into real revenue or market share; rising capture rates suggest stronger sales execution or product-market fit, while falling rates warn of competitive pressures or weakening appeal.
