A peg is a target price relationship, such as a stablecoin aiming at 1.00 USD.
Pegs are maintained by reserves, arbitrage, or algorithms. Confidence and redeemability matter as much as the target.
In research workflows, Peg is usually interpreted with Depeg, Stablecoin, and Arbitrage rather than as a standalone signal. Compare circulating float, unlock overhang, and where size can actually trade before trusting a breakout headline.
