Stock Perp Funding and Basis Risk

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. Annualizing the current rate assumes it stays constant; it is not a forecast of future payments.
• 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.

Example funding problem

A trader buys a stock perp because the underlying equity thesis is bullish, but funding is expensive and the reference market is not moving quickly. The trader can be right about direction and still bleed value through carry, spread, or liquidation pressure. Funding turns time into a cost.

Example basis problem

Basis becomes dangerous when the perp price and reference market separate. Thin liquidity, market-hour mismatch, earnings events, corporate actions, and crowded positioning can all widen the gap. A trader exiting during that gap may not receive the price implied by the reference chart.

Oracle quality questions

Ask what reference price the market uses, how often it updates, what happens when the underlying market is closed, and whether stale or stressed conditions are visible. If the page cannot explain the reference, the market should be treated as lower confidence.

Liquidity questions

A mark price is not executable depth. Inspect spread, visible size, impact, recent volume, and open-interest caps. A stock perp may look clean on a chart while still being expensive to enter or exit at the size a trader wants.

How to use the tools

Use the funding dashboard to identify carry pressure, the stock-perp screener to inspect live metadata, and the liquidation calculator to stress leverage. The goal is not to find a perfect number; it is to notice whether the position survives conservative assumptions.

Build a risk stack

Use a risk stack rather than one favorite metric. Funding tells you carry. Basis tells you tracking quality. Oracle details tell you reference quality. Liquidity tells you whether the mark price is tradable. Liquidation distance tells you how much room the account has if the market moves.

When to mark the market lower confidence

Mark a stock-perp market lower confidence when metadata is unclear, depth is thin, funding is extreme, the underlying reference has an event risk, or open-interest caps constrain behavior. Lower confidence does not always mean no trade, but it should mean smaller assumptions and clearer labels. A trader should know whether the concern is carry, tracking, oracle quality, or execution depth instead of seeing one generic warning. That precision helps the reader choose the next tool: funding dashboard, screener, source page, or liquidation calculator. It also makes future reviews easier for editors.

Simple summary

Name the risk source before deciding whether the market is usable for your size and holding period. Carry, basis, oracle quality, liquidity, margin, and event timing lead to different decisions, different tools, and different confidence levels for traders.
