Core concepts
Reading the premium
The premium is the one number specific to a tokenized market, and the one most easily misread. It is not a discount waiting to be captured.
What it measures
The token premium is the listing pool’s last quoted price set against the underlying share’s current value:
premium % = (pool quote ÷ share price − 1) × 100 AMZN, measured: 257.10 ÷ 266.22 − 1 = −3.43%
Why a wide gap usually means silence, not value
The pool quote changes only when somebody trades against that pool, and it arrives with no timestamp. A pool that last traded hours ago is still quoting an hours-old price while the share has kept moving. So the first thing a wide gap tells you is that the pool has been quiet.
The second consideration is the other side of the comparison. With the US exchange closed, the share’s price is itself a settled close. Both halves are then hours old and the gap is uninformative about anything except inactivity.
When the quote stops being a price
Past a plausible tracking range the pool quote is not a price at all. The terminal marks it as unusable and refuses to report a premium for it.
| Listing | Pool quote | Share | Gap |
|---|---|---|---|
| SPY | $769.36 | $769.33 | +0.004% |
| NVDA | $219.63 | $217.88 | +0.81% |
| AEHR | $110.41 | $81.34 | +35.7% |
| APLD | $152.46 | $25.52 | +497% |
The last row is a pool nobody has traded against in a long time. Rendering +497% as a premium would dress a dead quote as a market signal, so past a ten-percent divergence the interface relabels it and says plainly that the listing’s quoted price carries the same doubt — because it is that same quote.
How to read it correctly
- Check the exchange state first. Closed means both sides are stale.
- Check when the share last traded. The interface prints this beside the premium for exactly this reason.
- Treat a wide gap on a thin listing as evidence about liquidity, not about price.
- A gap that stays wide while the exchange is open and the share is genuinely current is the only case that says something about the pool.
