Key Terms

equity derivatives, single stock options, electronic trading, equity linked structured products

4 terms

equity derivatives financial

"completed the acquisition of European equity derivatives market maker Webb Traders"

Equity derivatives are financial contracts whose value is tied to a stock or a group of stocks, like a bet or an insurance policy based on a share's future price. They matter to investors because they let you protect against losses, amplify gains with less upfront cash, or take a position without owning the stock directly, which affects market risk, liquidity and how prices move.

single stock options financial

"specialises in single stock options market making for European and US"

Single stock options are financial contracts that give one person the right, but not the obligation, to buy or sell a specific company’s shares at a predetermined price before a set expiration date. Investors use them to bet on or hedge against a single stock’s movement—like buying short-term insurance or a leveraged ticket to bigger gains—but they require paying a cost upfront and can expire worthless.

electronic trading technical

"This addition also brings further electronic trading capabilities to Marex"

Electronic trading is the buying and selling of stocks, bonds, options and other financial instruments using computerized systems and networks instead of face-to-face or phone-based methods. It matters to investors because it makes trades faster, cheaper and available around the clock, improving price transparency and liquidity—think of it like shopping online versus going to a physical store, where speed and wider choice can change the price you pay and how reliably you can complete a purchase.

equity linked structured products financial

"enhance Marex’s established Equity Linked Structured Products platform"

A packaged investment that combines exposure to one or more stocks or equity indexes with derivative features, creating a custom payoff profile such as capped gains, periodic coupons, partial capital protection, or leverage. Think of it as a custom-made financial gadget built from stocks and options whose final return depends on specific conditions written into the product. It matters to investors because it changes the usual trade-off between risk and return, adds issuer credit and liquidity considerations, and can behave very differently from holding the underlying shares.
