What is the grey market anchor?

Grey market anchor uses pre-listing grey market performance as one short-term input for first-day judgment.

Plain meaning

Grey market trading happens before official listing and reflects off-exchange orders and sentiment from some brokers. The anchor considers return, intraday quality and activity.

Why it matters

Grey market can shape first-day expectations, but it is not the official market and may have limited liquidity. It is useful but unstable.

How to read it

Read it with public demand, greenshoe support, final pricing, market conditions and first-day turnover.

How it appears here

Backtests separate grey market and first-day targets, while grey intraday behavior can act as one stage-specific factor for first-day calls.

Common mistakes

Treating grey market close as first-day open or close.
Ignoring turnover and liquidity differences.
Assuming grey market direction must continue on listing day.
