Beta Hedging
Beta hedging is a strategy used to reduce the sensitivity of a portfolio to broader market movements by taking an opposing position in a market index or a highly correlated derivative. Beta measures the volatility of an asset relative to the overall market; a beta of one means the asset moves in lockstep with the market.
By shorting an index, an investor can neutralize the market risk of their portfolio, leaving only the alpha, or the return generated by specific asset selection. In crypto, this might involve hedging a portfolio of altcoins by shorting Bitcoin or an Ethereum-based index.
This allows traders to express a view on the relative performance of specific assets without being exposed to the volatility of the entire market. It is a sophisticated technique used to isolate and capture specific market inefficiencies.
