The tranche in a series of mortgage-backed securities that is the last one to receive payment. The Z-Bond is typically considered a high-risk investment.

As the holder of a Z-Bond, you wont receive any periodic payments. Instead, you get all the accrued interest payed out in a lump sum.

In the context of collateralized mortgage obligations (CMO), a Z-Bond is a bond that pay no coupon payments to the holder as long as principal is left to be paid on earlier bonds. Instead of paying out interest on the Z-Bond, the money is used to amortize the principal on the earlier series of bonds more quickly. The interest payable on a Z-Bond is added to its principal balance and becomes payable once there is no more payments to make on all the earlier series of bonds.

Zeta Model

The Zeta Model is a mathematical formula developed by NYU Professor Esward Altman in the 1960s. It is an attempt to calculate the chance of a public company going bankrupt within the next 2 years.

The model is specified as:

1.2A + 1.4B + 3.3C + 0.6D + 1.0E = the company’s Z-score
A = Working Capital/Total Assets
B = Retained Earnings/Total Assets
C = Earnings Before Interest & Tax/Total Assets
D = Market Value of Equity/Total Liabilities
E = Sales/Total Assets

The company’s Z-score is the predictor of bankruptcy within the next 2 years.

In the context of options, zomma is a measurement of the change in gamma in relation to changes in volatility of the underlying asset.

Zomma and gamma are both greeks, i.e. quantities representing the sensitivity of the price of derivatives to a change in underlying parameters on which the value of the instrument depends. They are called greeks since most of them are denoted by Greek letters.

Zomma is considered a third-level greek. Options traders chiefly use zomma when monitoring the effectiveness of gamma-hedged investment portfolios.
