Why Stock Tokens Trade at a Premium or Discount to the Stock
The common reasons a stock token's price differs from the stock: mismatched trading hours, liquidity, shares per token and mint/redeem barriers, and how to use premium data to find a better price.
A stock token rarely trades at exactly the share price. Sometimes it is a little more expensive (a premium), sometimes a little cheaper (a discount), and the gap differs between venues. Knowing where the gap comes from helps you avoid overpaying.
What premium and discount mean
We call the gap between a token and its stock the premium:
Premium = token price ÷ (underlying price × shares per token) − 1
- A premium of +0.30% means the token costs 0.3% more than the stock.
- A premium of −0.20% (a discount) means it costs 0.2% less.
The underlying price comes from the venues' index quotes for the stock, using the median when several venues quote it. See About our data for details.
Why premiums and discounts happen
1. Different trading hours
Most stock tokens trade around the clock, but the stock only has live quotes during market hours. Overnight and at weekends the token moves with sentiment while the underlying price stays near the close, producing a visible premium or discount that usually closes once the market reopens. That is why we flag the premium as indicative while the US market is closed.
2. Liquidity and spreads
Thinly traded tokens have wide bid-ask spreads, and the last trade can be stale. In thin on-chain pools a single trade can move the quote sharply. We only award "Best price" among tokens with enough volume and on-chain liquidity, and keep thin pools out of the premium rankings.
3. One token isn't always one share
This is the most common source of confusion. After a split or reverse split, or when an issuer turns dividends into extra shares, one token may represent 10 shares, 0.1 shares or 1.02 shares. If a stock splits 10-for-1 but each token still represents one pre-split share, the token looks ten times the share price, which is not a premium. We use the share count published by the venue, or apply a common split ratio when the price clearly matches one, and show "1 token ≈ N shares"; when we cannot confirm it we show no premium.
Ondo and xStocks turn dividends into extra shares, so tokens for high-yield stocks and ETFs tend to trade above the share price by roughly their accumulated yield.
4. Arbitrage has barriers
In theory, when a token drifts from the stock, traders can mint or redeem with the issuer to pull it back. In practice minting and redemption are usually limited to verified institutions with minimum sizes and timing rules, so small gaps can persist.
5. Moving between venues costs money
The same token can trade at different prices on an exchange and on-chain. Moving it between them costs fees and time, and gaps smaller than that cost don't get arbitraged away.
Using premium data when you buy
- Sort by premium on the stock page to find the cheaper venue, for example for NVDA or TSLA. "Best price" marks the cheapest actively traded option.
- Mind the clock: during US market hours tokens trade closest to the stock; outside them premiums can be larger.
- Check volume: a low-premium quote with almost no trading may not fill.
- Look at the history: the premium and price history on each stock page shows the last 7 or 30 days, so you can tell whether today's premium is unusually high.
- Scan the market: the rankings list the stock tokens with the highest premium and deepest discount right now.
