Interest that is due from the issue date of a new bond or from the last coupon payment date (existing bond) to the settlement date on an interest-bearing instrument. When the bond is traded in the secondary market, the buyer of the security pays the quoted price plus accrued interest when the bond trades “cum interest”, while the seller of the bond pays accrued interest to the buyer when the bond trades “ex interest”.

Alpha
A risk-adjusted measure of the so-called active return on an investment. It represents the return in excess of the compensation for the risk borne and is commonly used to assess active managers' performances. Often the return of a benchmark is subtracted to consider relative performance, which yields Jensen's alpha.
The alpha coefficient (αi) is a parameter in the capital asset pricing model (CAPM). It can be shown that, in an efficient market, the expected value of the alpha coefficient equals the return of the risk free asset: E(αi) = rf.
Therefore the alpha coefficient indicates how an investment has performed after accounting for the risk it involved:
αi < rf: the investment has earned too little for its risk (or was too risky for the return)
αi = rf: the investment has earned a return adequate for the risk taken
αi > rf: the investment has a return in excess of the reward for the assumed risk
American-style Option
A financial option that may be exercised at any time during its term (life), from inception (trade date) to the maturity date.
Amortising Swap
An interest rate swap structured so that the notional principal decreases over the life of the swap in accordance with a pre-specified schedule.
Annuity
An investment that makes a series of equal payments over a specified time frame. These payments occur at regular intervals (e.g. monthly, semi-annually or annually) and are of equal value (e.g. R1,000 monthly for twelve months).
Annuity Duennuity
Investments/contracts can be structured so that payments (contributions) are made in advance (beginning of the period) rather than in arrears (end of the period) as in the case of an ordinary annuity. This series of cash flows is known as an annuity due.
Arbitrage
The act of taking advantage of temporary price differences between markets, e.g. the spot and forward markets, or the forward FX market and the money markets. Arbitrage is possible when one of the following three conditions is met:
Arbitrageur
A person who engages in arbitrage activities is known as an arbitrageur.
Asian (Average Rate) Option
An option that, upon exercise, entitles the buyer (holder) to receive/pay the difference between the exercise (strike) price and the average price of the underlying during the life of the contract.
Ask (Price)
Also called offer price. The price that the seller of goods/instruments/securities is willing to accept when selling those particular goods. The term “ask price” is especially used in stock trading as a contrast to the term “bid price”. The difference between the ask price and the bid price is called the bid-offer spread.
Asset Backed Security (ABS)
Asset-or-Nothing Binary Option
Pays the value of the underlying security if the option ends in-the-money, or nothing if it ends out-the-money.
Asset Swap
A transaction where the cash flows of an underlying asset are swapped or exchanged. For example, an investor swapping the fixed rate coupons on a bond for a floating rate cash flow on another asset.
At-the-Money-Forward
An option is at-the-money-forward if the strike (exercise) price/rate is equal to the forward price of the underlying security. An at-the-money-forward option has no monetary (intrinsic) value, only a time value.
At-the-Money Option
An option (call/put) whose strike price is equal to the current, prevailing market price of the instrument in the underlying market.
At-the-Money-Spot
An option is at-the-money if the strike (exercise) price/rate is the same as the current market price of the underlying security on which the option is written.
