Liquidity Adjustment in Multivariate Volatility Modeling: Evidence from Portfolios of Cryptocurrencies and US Stocks

We develop a liquidity-sensitive multivariate volatility framework to improve the estimation of time-varying covariance structures under market frictions. We introduce two novel portfolio-level liquidity measures, liquidity jump and liquidity diffusion, which capture magnitude and volatility of liquidity fluctuation, respectively, and construct liquidity-adjusted return and volatility that reflect real-time liquidity…

Hedging and Leveraging: Principal Portfolios of the Capital Asset Pricing Model

The principal portfolios of the standard Capital Asset Pricing Model (CAPM) are analyzed and found to have remarkable hedging and leveraging properties. Principal portfolios implement a recasting of any correlated asset set of N risky securities into an equivalent but uncorrelated set when short sales are allowed. While a determination of principal portfolios in general requires a detailed knowledge of the covariance…

Banking

Bank CDS Index

Bank CDS Index tracks the cost of insuring major bank credit risk and serves as a real-time indicator of banking-system stress and confidence.

Banking

Fractional-Reserve Banking

Fractional-reserve banking is taking deposits and holding only a fraction in reserves or liquid assets — credit creation with a run risk.

Banking

Leverage Ratio Constraint

Leverage Ratio Constraint — Non-risk-weighted capital floor binding balance-sheet capacity.

Banking

Regional Bank ETF

Regional Bank ETF performance helps track stress in smaller and mid-sized banks, especially around deposit stability, asset quality, and local credit conditions.

Banking

Systemic Risk Indicator

Systemic Risk Indicator — Aggregate capital shortfall under stress — connects banking to macro hedges.

Credit

CDX HY Index

CDX HY Index tracks the cost of insuring a basket of North American high-yield corporate credit and serves as a sensitive gauge of credit risk appetite and stress.

Credit

Credit Rating

A credit rating is an agency’s opinion of relative default risk — a letter grade that gates mandates, not a market price.

Credit

Credit Valuation Adjustment

Credit Valuation Adjustment — Adjustment to derivative value for counterparty default risk.

Credit

Default Risk

Default risk is the chance the issuer misses a contractual payment — the event credit spread is trying, noisily, to price.

Credit

High Yield OAS

High Yield OAS measures the spread of high-yield corporate bonds over risk-free Treasuries after adjusting for embedded options, serving as a key gauge of speculative credit stress.

Credit

Junk Bond

A junk bond is a high-yield, below-investment-grade credit — more equity-like default risk, still quoted in spread and price.

Credit

Loan Officer Survey

The Loan Officer Survey tracks bank lending standards and loan demand, providing insight into whether credit supply is tightening or easing in the real economy.

Credit

Loss Given Default

LGD is 1 minus recovery — the fraction of exposure lost when default happens.

Credit

Probability of Default

PD is the probability a name defaults over a horizon — real-world for books, risk-neutral for CDS.

CTA

AI / Machine-Learning CTA

A CTA whose signals come from ML (trees, nets, representations) rather than a hand-written MA — still a futures risk engine underneath.

CTA

ATR Unit Sizing

Size each new futures position so that 1 ATR move equals a fixed fraction of equity — the Turtle risk unit, still the cleanest per-trade language.

CTA

CTA Correlation-Adjusted Sizing

Shrink size when markets are moving together so that ‘20 commodities’ are not one energy-risk factor wearing 20 tickers.

CTA

CTA Long/Short Symmetry

Whether the program treats shorts with the same rules and risk as longs — the difference between a two-way CTA and a long-biased TAA in a futures wrapper.

CTA

CTA Options Strategy

Express views with listed options on futures — defined-risk directional, calendars, or vol — still a CTA if the underlying is a commodity interest.

CTA

CTA Pyramiding / Scale-In

Add units as the trend extends — more risk on a working trade — instead of a single full-size entry.

CTA

CTA Volatility Targeting

Scale the whole book (or each market) so forecast σ hits a target — the reason a 15% vol CTA is not ‘more leveraged crude’ in a quiet month.

CTA

Diversified CTA

A program that risks money across the four big futures groups — equity indices, bonds/STIR, FX, and commodities — rather than a single pit.

CTA

Multi-Strategy CTA

A single platform that allocates risk across trend, carry, short-term, RV, and sometimes options — a house of sleeves, not a style-pure trend shop.

Derivatives

Implied Volatility Surface

Implied Volatility Surface — Strike and tenor structure of implied vol, the core object for vol trading and risk.

Derivatives

Skew

Skew measures the relative richness of downside versus upside implied volatility, helping track hedging demand and asymmetry in market risk pricing.

Derivatives

Vega Exposure

Vega Exposure — Sensitivity to implied volatility changes — core risk for vol books and structured products.

Derivatives

VIX Index

VIX Index measures implied volatility in S&P 500 options and is widely used as a shorthand for equity market fear and risk aversion.

Desk Slang

CS01

CS01 is the dollar value of one basis point of credit spread — how much the book makes or loses if the name or index OAS/CDS widens by 1 bp.

Desk Slang

DV01

DV01 is the dollar value of one basis point: how much the position’s mark changes if the yield (or the curve point you risk on) moves by 0.01%.

Desk Slang

Risk-On Risk-Off

Risk-on / risk-off (RORO) is a one-factor tape: the same risk appetite impulse hits credit, EM, high-beta equity, and vol in one direction while Treasuries, the dollar, and gold take the other side.

Desk Slang

TINA

TINA — There Is No Alternative — was the 2010s slogan that zero rates left no choice but equities (or credit), compressing risk premia because cash paid nothing.

Desk Slang

Wrong-Way Risk

Wrong-way risk is when exposure rises at the same time the counterparty’s credit worsens — the hedge or the receivable fails exactly when you need it.
