Korea Is Bet On Four Times Over, and Half of It Is Not in This Group

TL;DR

One country's exposure is listed four times on this book — single name, single name at 2x, broad index at 1x, broad index at 3X. But this group holds only two of them, and the label "Asia" itself ties together two regions that moved in opposite directions.

• Korea is bet on four times across the book, totalling $50.76M, 3.85% of it: SKHYB (SK Hynix spot, $29.12M), SKUUB (SK Hynix 2x, $434.0K), KORUB (MSCI South Korea 3X, $10.72M), EWYB (MSCI South Korea 1x, $10.48M). Only 41.8% of it is in this group — the other two sit in group 3 and group 2.
• On the same index over the same 30-day window, the realized 3X-to-1x ratio is 2.795, below the nominal 3. KORUB −49.66% against EWYB −17.77%; a static 3x would give −53.31%, so the actual fall is 3.65 percentage points shallower.
• SKUUB's 30-day field covers 5 days. It listed 2026-10-26, and both its 30d and 7d fields read −9.85% — the same truncated window. So this four-rung leverage ladder cannot be compared across on 30-day returns.
• Counter-example: KORUB ranks only 4th on range width in its own listing cohort. Among the ten that listed the same day, INTWB 5.583x, SNXXB 3.243x and MVLLB 3.075x all exceed its 2.669x, and all three are 2x single-stock leveraged ETFs. The leverage multiple does not determine range width; the underlying does.
• The harder counter-example: the plain common stock AXTIB, listed the same day, has a width of 2.658x, 99.6% of KORUB's. A plain common stock and a 3X country ETF travelled nearly identical range widths over the same 103-day window.
• KORUB is not the worst 30-day performer on the book either. It ranks 6th, and four of the five ahead of it are leveraged ETFs on US semiconductors (INTWB −78.03%, SNXXB −61.18%, SOXLB −51.90%, MVLLB −51.66%).
• The label "Asia" ties two opposite things together. The Korean half of this group, $21.20M (64.0%), is −17.77% and −49.66% over 30 days; the Chinese half, $11.93M, is −14.78%, −9.19% and +0.57% — a spread of 50.23 percentage points inside one group.

1. What these five are

bStocks is Binance's own on-chain equity issuer (entity BTech Holdings Limited, ADGM / FSRA listed certificates, single chain BNB Chain, Binance only). CoinMarketCap reports 105 instruments; this piece uses a snapshot covering 100 of them, timestamped 2026-10-31T06:06:52Z.

Group market cap is $33.13M, 2.5% of the book; volume is $23.21M, 2.7%. The five split across two regions: two Korean (KORUB and EWYB, $21.20M or 64.0%) and three Chinese (BABAB, PDDB and KSTRB, $11.93M or 36.0%).

What this group cannot hold has to be said first. Asia exposure on this book totals $71.70M, and this group is only 46.2% of it:

• Two more Korean instruments are not in this group: SKHYB (SK Hynix, $29.12M, 11th on the book) sits in the memory supercycle group, and SKUUB (SK Hynix 2x, $434.0K) in the single-stock 2x ETF group.
• Taiwan's TSMB (TSMC ADR, $9.01M) sits in the semiconductor design and fabs group. It listed the same day as BABAB (2026-07-13), at $9.01M against $8.96M — almost identical in size.

So this piece does not make any panoramic claim about "Asia exposure in this channel" — half of that label lives in other groups, and sections 2 and 5 both use that fact to bound the conclusions.

2. Korea is bet on four times over

This is the one structural finding in this group that holds completely in the data. The snapshot's underlying.name and leverage fields state all four identities outright:

$50.76M in total, 3.85% of the book's market cap. One country's exposure comes in four ways on this book: the single name, the single name at 2x, the broad index, and the broad index at 3x. SKHYB's spot behaviour and its Korean listing were already covered in group 3, and SKUUB belongs to group 2 as a single-stock 2x product; this piece repeats neither and puts them in this table only to establish one thing: 58.2% of this trade is not in this group.

But the ladder cannot be compared across on 30-day returns, because of SKUUB. It listed 2026-10-26, giving it 5 days to the snapshot, and in the snapshot both its 7d and 30d fields read −9.85% — the same truncated window reported twice. So reading "2x fell less than 1x" is simply wrong: its window is a sixth of the others'. For any instrument live less than 30 days, the 30d field covers the whole span from listing to snapshot, not 30 days. PDDB (32 days) just clears it; KSTRB (12 days) does not — its −14.78% covers 12 days.

What can be compared is the same-index, same-window pair. The underlying names of KORUB and EWYB both state the same index (MSCI South Korea), and both have been live more than 30 days:

Same index, same 30-day window, and the realized 3X ratio is 2.795, below the nominal 3. That direction is the one daily-reset leverage should produce in a sustained one-directional decline: resetting exposure to net asset value each day means the principal exposed shrinks as the asset falls, so cumulative loss comes in under a static 3x. Had the month been choppy rather than steadily down, the sign would reverse. To be clear about the measure: the snapshot has no daily path, so this piece cannot decompose those 3.65 percentage points into how much came from the reset and how much from each token's own pricing deviation — what is compared here is two token price changes, with the 1x token standing in for the index rather than being it.

This measures the same mechanism as the directional 3X group from the other side: that piece held the multiplier fixed (two ±3X pairs) and attributed the difference to the index; this one holds the index fixed and attributes the difference to the multiplier. Together they say that on this book "3X" is a statement about path, not a multiplication of outcomes.

3. The Chinese half and the Korean half moved in opposite directions

The 30-day spread inside this group is 50.23 percentage points — from KORUB's −49.66% to PDDB's +0.57%. PDDB is one of the book's 18 positive instruments.

This is not "Asia fell" or "Asia rose" but three independent things: a Korean broad index magnified 3x and down by half; two Chinese ADRs between a mild decline and flat; and a Chinese STAR Market ETF down 13.25% over 7 days, having covered its entire −14.78% within 12 days. Weighting those into a single "Asia exposure" number produces something that corresponds to no tradable position.

One more thing worth isolating: BABAB's turnover of 0.276x is the lowest in this group and 90th on the book, while its position in range of 3.5% is also the group's lowest. An $8.96M instrument, 28th on the book by market cap, is simultaneously the quietest in this group and the one closest to the bottom of its own range. The previous piece already quantified how size and turnover run backwards on this book; this one does not repeat it and simply records BABAB as another instance of the pattern.

4. Counter-examples: the 3X label does not predict width, and a 12-day narrow range says nothing

Counter-example one: KORUB ranks only 4th on width in its own listing cohort. Ten instruments listed 2026-07-20, over the same 103-day window:

All three 2x single-stock leveraged ETFs are wider than this 3X country ETF, and INTWB's 5.583x is 2.09x KORUB's. The leverage multiple does not determine range width — the underlying does. The same table holds another 3X: TQQQB's 1.512x is only 56.7% of KORUB's, so two broad-index leveraged ETFs that are both 3X, listed the same day over the same 103-day window, differ by 1.77x on width. TQQQB was already written up as a counter-example in the directional 3X group; this piece does not repeat that conclusion and notes only that it sits in the same cohort table as KORUB, so this comparison's window is strictly identical.

Counter-example two, the hardest in this section: the plain common stock AXTIB, listed the same day, has a width of 2.658x, 99.6% of KORUB's 2.669x. AXT Inc is not a leveraged product, not a country ETF, and has no daily-reset structure at all — it is an ordinary common stock, and over the same 103-day window its high-to-low ratio differs from a 3X Korea ETF's by 0.4%. If the "3X" label carried information about path width, those two numbers would not sit that close.

Counter-example three: KORUB is not the worst 30-day performer on the book. Ranked by 30-day change it is 6th:

Four of the five ahead of it are leveraged ETFs on US semiconductors. So "3X Korea is the disaster of this book" does not hold — the worst of this month were the leveraged semiconductor products, and SOXLB's −51.90% is also a 3X, running 2.24 percentage points deeper than Korea with semiconductors as the underlying.

Counter-example four, a measurement problem rather than an argument: KSTRB's narrow 1.224x says nothing. It listed 2026-10-19 and has been live 12 days. Five instruments listed that day:

All five widths fall between 1.031x and 1.242x, including a 3X Treasury leveraged ETF. In 12 days even a 3X product only manages 1.081x — that is not because they are calm, it is because the window is too short for extremes to have appeared yet. So KSTRB's narrow range carries no information about STAR Market volatility, and section 8 lists this among the measurement limits.

5. Putting this group back in the distribution

First, this group's turnover is slightly above the book, 5th among the eight groups published in this series.

This is the smallest of the eight by market cap ($33.13M), and its turnover of 0.7005x sits essentially at the book's level. That turnover is almost entirely carried by KORUB: one instrument at 1.207x with $12.94M of volume accounts for 55.8% of the group's volume while holding only 32.4% of its market cap. Take KORUB out and the remaining four are $22.41M in market cap, $10.27M in volume and 0.4581x in turnover — below the book, and below every group except group 1.

Second, the Korea trade as a whole turns 0.7285x, close to this group. Of the four instruments KORUB is fastest (1.207x) and EWYB slowest (0.562x), while the largest, SKHYB, runs 0.609x. The same shape again: the large ones are slow and the leveraged ones are fast.

Third, the kind composition here is the most mixed in the series so far. The five span three kinds: one leveraged ETF, two ETFs and two ADRs — the book has only 6 ADRs in total, and this group holds 2 of them (BABAB, PDDB), which with TSMB in group 4 means three Asian ADRs account for half the book's ADRs. For comparison, group 6 is three common stocks plus two unclassified, and all five in group 7 are common stock.

Fourth, where the sizes sit. The book has 7 instruments at $50M or more, 12 at $25M or more, 61 under $5M, 33 under $1M, with a median of $2.39M. Three of these five — KORUB, EWYB and BABAB — fall between $8.96M and $10.72M (21st, 23rd and 28th on the book), PDDB at $2.14M is below the median, and KSTRB at $833.9K joins the 33 under $1M. Not one reaches the $25M bucket — the only instrument in the Korea trade that does is SKHYB ($29.12M), and it is not in this group.

6. Structure

All of this comes from this site's issuer record, the same data behind /stocks/bstocks:

• Legal wrapper: tracker certificate, ADGM / FSRA listed certificates, issuing entity BTech Holdings Limited. The holder receives a certificate tracking the underlying price, not a registration of units.
• Voting rights: none.
• Dividends: passed through, but after 30% US withholding, then reinvested via a multiplier.
• Redemption: supported, KYC required, $5 minimum.
• Proof of reserve: attestation, not live on-chain proof.
• US persons: blocked.
• Chain: BNB Chain only. BSC deposits only; sending on the wrong network loses the assets.
• Issuance model: exchange self-issued; the only venue is Binance, operated by the issuer.
• Grade on this site: B.

Three of those carry concrete meaning for this group.

The "30% US withholding first" line deserves separate attention, because none of these five underlyings is a US company. The dividend mechanism this site records is pass-through, then 30% US withholding, then reinvestment via a multiplier. But BABAB and PDDB are ADRs, and EWYB, KORUB and KSTRB are US-registered ETFs. The dividend character of those three instrument types differs under US tax law, while the issuer record gives one uniform 30% figure — this piece cannot verify how that figure actually applies to non-US underlyings, only note that the record states it, and that this is one of the reasons section 8 gives no premium number.

The underlying is already a wrapper in its own right. BABAB's underlying is Alibaba's ADR, itself a US depositary institution's receipt against foreign shares; the underlyings of EWYB, KORUB and KSTRB are ETF units. So buying BABAB is a certificate over a certificate, and buying KORUB is a certificate wrapped around units of a daily-reset leveraged ETF — in section 2's 2.795x realized ratio, the daily reset happens inside the underlying ETF and has nothing to do with the bStocks layer, but once the two layers stack the holder sees only the final price.

"No voting rights" means little for the ETF underlyings and something for the two ADRs. An ETF unit does not give its holder votes in the constituents anyway, so the clause adds no new forfeiture for EWYB, KORUB or KSTRB; but the ADRs underlying BABAB and PDDB typically do carry voting arrangements in public markets. One issuer clause means different things inside this group, which is one cost of grouping five heterogeneous instruments together.

7. This snapshot was taken on a Saturday

The timestamp 2026-10-31T06:06:52Z is Saturday morning UTC. The US cash market closed Friday at 20:00 UTC and does not reopen until Monday — for more than two days after this snapshot, these token prices are the only prices these five instruments have.

This group carries a wrinkle the others do not: the markets where these underlying assets live are not in the same time zone as the US market that prices them. Korean and Chinese exchange hours barely overlap with US hours, and EWYB, KORUB and KSTRB are themselves US-traded ETFs — which means these instruments already sit behind one time-zone layer on a weekday, and on the weekend the US layer closes too. This piece draws no quantitative inference from that (the snapshot is a single moment and cannot see session structure), and notes only that KORUB's 24-hour change of −3.59% occurred along a chain where both the underlying Korean market and the US market were closed.

The same issuer has already provided a quantified version: one stock, four books laid AAPL's four tokenized versions side by side on a single Saturday and concluded that a quote during non-trading hours is a market maker's opinion, not a market price.

The 24-hour window in this piece runs Friday 06:06 UTC to Saturday 06:06 UTC, which includes a full Friday US trading session, so these are not purely closed-market quotes.

8. What this method cannot compute

First, the 30d field is not 30 days for any instrument live less than 30 days. This is the most important measurement note in this piece. SKUUB has been live 5 days and its 7d and 30d both read −9.85%; KSTRB has been live 12 days and its −14.78% covers 12 days. So section 2's four-rung leverage ladder can only be set side by side structurally, never compared on returns — only SKHYB (114 days), KORUB (103 days) and EWYB (132 days) are comparable.

Second, the range-width windows are unequal, and unusually scattered here. The five are 103 / 132 / 110 / 32 / 12 days. Only KORUB, EWYB and BABAB clear 100 days, so PDDB and KSTRB do not enter the comparison across the 46 instruments live 100 days or more. The 12-day cohort table in section 4 already demonstrates the point: all five land between 1.031x and 1.242x, narrow not because they are calm but because there has not been enough time.

Third, it cannot compute index constituents. Section 2 compares KORUB and EWYB as two leverage rungs on one index on the strength of both underlying.name fields stating MSCI South Korea. But the snapshot has no index constituent or weight field, and no quote for the index itself — so that 2.795 is the ratio of two token price changes, not a leveraged ETF's realized multiple against its index. The 1x token stands in for the index here, and that proxy carries its own premium or discount and its own liquidity.

Fourth, it cannot compute the daily path, so leverage decay cannot be decomposed. Section 2's 3.65 percentage point gap (actual −49.66% against a static triple's −53.31%) matches the direction a daily reset should produce in a sustained one-directional decline, but the snapshot has only four point-in-time fields (24h / 7d / 30d / high and low since listing) and no daily series — so this piece can compute no realized volatility and cannot say how much of those 3.65 points came from the reset versus each token's own pricing deviation.

Fifth, it cannot compute premium or discount. The snapshot carries only the token's own price, with no reference price for the underlying. More fundamentally, the bStocks dividend mechanism is "30% US withholding, then reinvested via a multiplier" — without knowing the current multiplier, the token price and the underlying unit price are not comparable in the first place. This group adds a further problem: the five underlyings are ADRs and units of US-registered ETFs, and how that uniform 30% figure lands on them is not stated in the snapshot and has not been verified here.

Sixth, it cannot compute units per token. The snapshot has no conversion ratio. KORUB trades at $10.61 and its circulating supply is in the snapshot, but without the ratio those numbers cannot be converted into any count of ETF units. Every market cap in section 2's table is a comparison between token floats.

Seventh, market cap is the CMC measure (price times circulating supply), and the book total of $1,318.38M is the sum of these 100 rows; the bStocks line on this site's /stocks page shows an on-chain size of $914M — two numbers from different sources at different moments that will not tie. This piece uses the former throughout.

Eighth, 100 of 105, and this directly affects two ratios in this piece. CMC reports 105 instruments and the snapshot in hand holds 100. So the accurate phrasing of "the Korea trade has four instruments" is "four among these 100 rows," and $50.76M and 3.85% are on that same basis — if any of the missing 5 is a Korean or Chinese instrument, both section 1's 46.2% and section 2's 41.8% change.

Ninth, turnover is 24h volume divided by market cap. A small denominator inflates the ratio. These five span $833.9K to $10.72M, a factor of 12.9 — though this group happens to run the other way: the largest, KORUB, has the highest turnover, while the smallest, KSTRB, at 0.560x is among the lowest, so the turnover differences here are unlikely to be mostly a denominator effect.

Conclusion. On this book one country's exposure has been built into four instruments — SKHYB on the single name, SKUUB at 2x, EWYB on the broad index at 1x and KORUB on the broad index at 3X, totalling $50.76M or 3.85% of the book, of which 58.2% is not in this group (SKHYB in group 3, SKUUB in group 2). That is the one structural finding here that holds completely, because its basis is the snapshot's underlying.name and leverage fields and requires no inference.

Only one pair in that ladder can actually be computed: same MSCI South Korea index, same 30-day window, KORUB −49.66% against EWYB −17.77%, a realized ratio of 2.795 below the nominal 3, falling 3.65 percentage points short of a static triple — the direction a daily reset should produce in a sustained one-directional decline, and as far as it can be taken, since the snapshot has no daily path. SKUUB cannot enter that comparison: it has been live 5 days, and its 30d and 7d fields are the same truncated window.

And the "3X" label does not predict width in cross-section. KORUB's 2.669x ranks only 4th among the ten instruments in its own cohort, with all three 2x single-stock leveraged ETFs wider and INTWB at 2.09x its width; the plain common stock AXTIB, listed the same day, reaches 99.6% of it; and TQQQB, also a 3X, is only 56.7% of it. Nor is it the worst faller on the book: 6th over 30 days, with four of the five ahead of it leveraged ETFs on US semiconductors.

One last thing to state plainly: the label "Asia exposure" ties two regions that moved in opposite directions. The Korean half of this group, $21.20M, fell 17.77% and 49.66%; the Chinese half, $11.93M, ran −14.78%, −9.19% and +0.57%, a spread of 50.23 percentage points, with PDDB among the book's 18 positive instruments. Add Taiwan's TSMB in group 4 and the two SK Hynix instruments in groups 2 and 3, and 53.8% of Asia exposure on this book is outside this group — which is why this piece offers no panoramic conclusion about how this channel treats Asia.
