## Statistical Arbitrage Models

Statistical arbitrage models use historical data and mathematical relationships to identify temporary price deviations between correlated assets. Unlike pure arbitrage, which is risk-free, statistical arbitrage is based on the expectation that prices will eventually revert to their historical mean.

Traders build portfolios of long and short positions to hedge against general market movement while profiting from the spread between assets. These models are complex and require rigorous testing to ensure their validity.

They are widely used in traditional finance and are increasingly applied to cryptocurrency markets. Success depends on the stability of the correlations and the ability to accurately forecast price movements.

It is a powerful tool for generating returns in diverse market conditions. Understanding these models requires a solid foundation in quantitative finance and statistics.

## Glossary

### [Crypto Derivative](https://term.greeks.live/area/crypto-derivative/)

Instrument ⎊ A crypto derivative is a contract deriving its valuation from an underlying digital asset, such as Bitcoin or Ethereum, without requiring direct ownership of the token.

### [Implied Volatility](https://term.greeks.live/area/implied-volatility/)

Calculation ⎊ Implied volatility, within cryptocurrency options, represents a forward-looking estimate of price fluctuation derived from market option prices, rather than historical data.

### [Crypto Options](https://term.greeks.live/area/crypto-options/)

Asset ⎊ Crypto options represent derivative contracts granting the holder the right, but not the obligation, to buy or sell a specified cryptocurrency at a predetermined price on or before a specified date.
