Stock Perp Funding, Basis, Oracle, And Liquidity Risk

Direct answer

The key stock-perp risks are funding, basis, oracle quality, liquidity, and margin. Funding is the recurring transfer between longs and shorts. Basis is the gap between the perp and the reference price. Oracle quality matters because the contract needs a reliable external reference. Liquidity matters because a visible mark price is not the same as executable depth.

Funding risk

Funding can make it expensive to hold a crowded position. A long that pays funding every hour may lose even if the mark price moves sideways. A short can face the same problem when funding flips.

Basis risk

Basis is the difference between the derivative price and the reference market. It can widen when liquidity is thin, when the underlying market is closed or stressed, or when traders crowd one side of the book.

Oracle and liquidity checklist

• Check whether the market is builder-deployed and what metadata is visible.
• Check funding direction and annualized carry before assuming the trade is cheap.
• Check impact spread and visible depth before relying on the mark price.
• Check open interest caps and max leverage for crowding and risk constraints.
• Treat market holidays, earnings, and corporate actions as extra research prompts.
