NTSD – The What, Why, and How

NTSD is a new ETF from WisdomTree that launched on March 19, 2026, on the NYSE. Its full name is the WisdomTree Efficient U.S. Plus International Equity Fund, and it's the newest member of WisdomTree's growing family of capital-efficient ETFs — a lineup that has evolved considerably since the original NTSX launched in 2018.

If you're new to these funds, go read my post on NTSX first where I fully explain the philosophy and reasoning behind the creation of these products. I won't repeat all that stuff here, since most people interested in this fund will almost certainly already be familiar with the other products in this lineup and the theory behind them.

The core idea is to use the same 90/60 framework WisdomTree pioneered with NTSX, but whereas NTSX pairs U.S. stocks with Treasury bond futures, here with NTSD we're pairing U.S. stocks with developed international equity futures. The result is a fund that gives you $1.50 of global equity exposure for every $1.00 you invest – $0.90 in U.S. stocks and $0.60 in MSCI EAFE developed international equity futures – without requiring you to sell anything you already own.

Usually when wanting to add a diversifying asset of any sort, you'd be forced to sell something to make room. WisdomTree's answer to that problem is capital efficiency via futures. Rather than allocating 100% of your capital to a single exposure, futures allow you to gain notional exposure to an asset using a fraction of that capital as collateral. The remainder can be invested in something else. The result is 150% total exposure.

Put another way, NTSD is effectively 1.5x leverage on 60% U.S. stocks and 40% international EAFE stocks, thus the 90/60 allocation. WisdomTree calls this “accounting leverage” to distinguish it from borrowed capital. The fund doesn't take out a loan. It uses the mechanics of futures contracts to extend exposure beyond 100%.

Specifically, NTSD is straightforwardly holding 90% of its assets in 500 largest U.S. stocks by market cap. Savvy readers will recognize that as the famous S&P 500 Index, but note that NTSD is holding the individual stocks themselves, not an S&P 500 fund.

Then for the international exposure, 10% of assets are in cash (T-bills) as collateral for international developed markets stock futures, providing 60% notional exposure. This is the overlay – the “plus international” in the fund's name.

The MSCI EAFE Index tracks large- and mid-cap equities across 21 developed markets in Europe, Australasia, and the Far East, excluding the U.S. and Canada. Think Japan, the UK, France, Germany, Switzerland, Australia. By holding EAFE futures rather than the actual stocks, NTSD can gain this exposure using only a small amount of collateral rather than full capital.

So if you're familiar with Vanguard tickers, think of NTSD as roughly 60% VOO and 40% VEA and then lever that up 1.5x. (Technically, VEA is not EAFE, so the fund IEFA would be more accurate, but many are not immediately familiar with that ETF.)

WisdomTree goes into plenty of detail on the merits of global stock market diversification per se in their marketing materials for this fund that I won't repeat here for the sake of brevity, but I have a whole separate post delineating that idea here.

NTSD rebalances quarterly, and also triggers a rebalance anytime equity or futures exposures deviate by more than 5% from their targets between scheduled dates.

NTSD has an expense ratio of 0.35%.

Use Cases for NTSD

NTSD may appeal to the U.S. stocks investor who's curious about international equities diversification but doesn't want to give up U.S. exposure. NTSD effectively allows such an investor to layer international exposure on top of existing core U.S. equities without giving up anything. This is the specific use case suggested by WisdomTree themselves. More people may be in this camp after seeing international stocks beat U.S. stocks for 2025 and 2026 YTD after Q1.

From another perspective, an investor who's already down with international equities diversification may simply want to ratchet up exposure without borrowing themselves, so for them NTSD provides 1.5x leverage on a portfolio of U.S. stocks and EAFE stocks.

The third investor who may appreciate NTSD is one who wants to diversify into additional uncorrelated assets like bonds or gold without giving up core global equities exposure. 67% NTSD and 33% bonds, as a hypothetical example, would provide effective exposure of 60% U.S. stocks, 40% EAFE stocks, and 33% bonds, for a total 133%.

NTSD Tax Treatment

Something I harped on in my NTSX review is its relative tax efficiency.

NTSX's Treasury futures are Section 1256 contracts, which means they're taxed at a blended 60% long-term / 40% short-term capital gains rate regardless of holding period, rather than as ordinary income the way direct bond interest would be taxed. This made NTSX genuinely one of the most tax-efficient leveraged products available, appropriate even for taxable accounts.

But here with NTSD, that consideration is basically reversed. NTSD's EAFE futures are also Section 1256 contracts, which means they get the same 60/40 tax treatment. But this is worse at any income level compared to long term capital gains for stocks, which is how a fund like VEA or IEFA would be treated.

Still, NTSD does package global equity exposure into a structure that avoids taxable rebalancing events, as the fund handles rebalancing internally without triggering capital gains.

Risks for NTSD

The obvious risk here with NTSD is that both sleeves are straight equities risk and then we're levering that up 1.5x. So if the aforementioned 60/40 portfolio of US and EAFE stocks falls 10%, for example, NTSD will fall roughly 15%. Many investors already don't have the stomach for 100% stocks, much less 150%.

WisdomTree seem to sort of gloss over this fact in their literature in my opinion. They've positioned this product as – and the verbiage in the launch announcement communicates – the hypothetical investor wanting to mitigate potential regret by not giving up any U.S. exposure in case the U.S. continues to outperform international but also simultaneously wanting international exposure in case international outperforms.

Once again, the solution, they maintain, is to keep the core U.S. exposure intact wholly and then just layer on some international exposure, providing the best of both worlds. That sounds nice, but appreciate that this is a very gentle, generous, euphemistic way of basically saying adding beta on top of beta and invariably increasing volatility and risk by going from 100% stocks to 150% stocks.

Also appreciate that, once again, this is not at all the same thing as what NTSX/NTSI/NTSE do, wherein the gentle “layering on top” phrasing is actually appropriate because the assets have independent sources of risk. Those funds have stocks and bonds, which is a case of structural asset class diversification. NTSD's two equity sleeves are naturally highly correlated here (0.86 over the past 3 decades). Again, don't expect a volatility or drawdown reduction relative to 100% U.S. stocks.

The other obvious thing at this point is that NTSD just launched, so whether or not AUM will materialize remains to be seen. NTSI and NTSE still aren't exactly huge years later, so we'll have to wait and see. Look out for wide bid-ask spreads right now.

NTSD Financing Costs and Roll Costs

Speaking of spreads, let's briefly talk about the excess financing spread for the EAFE equity futures. You didn't think those were free, did you?!

With the older members of the family, NTSX, NTSI, and NTSE, they're using U.S. Treasury futures, for which there's basically zero – and sometimes even negative – excess financing costs. S&P 500 equity futures are basically the same story.

But remember here we're talking about EAFE equity futures, for which the spread would probably be 0.5% at best and about 1.25% at worst. Let's err on the side of caution and call it an even 1%.

And then don't forget the 10% collateral in the form of 3-month T-bills earns the risk-free rate, so it claws back a little bit.

Putting those together, total financing drag should be about:

 (SOFR + 1%) * 0.6 - (RFR * 0.1)

where SOFR is the Secured Overnight Financing Rate and RFR is the risk-free rate.

SOFR and RFR are around 3.65% at the time of writing, putting total financing drag here at about 2.43% if my assumptions and napkin math are right. This is embedded in the price of the futures contracts.

Then we've got roll costs of the futures contracts, which are pure execution costs that are not embedded. Once per quarter, NTSD is closing the expiring contract and opening another. This incurs transactional frictions because, once again, EAFE futures are traded much more thinly than, say, S&P 500 futures.

WisdomTree have to pay the bid-ask spread twice per quarter, once to exit the old contract and once to enter the new contract. Let's call it a spread of 5 bps, or 0.05%. Paying that on both trades 4 times per year makes the annual roll cost approximately:

 0.05% * 2 * 4 * 0.6 = 0.24%

Adding that to our financing cost, that's a drag of 2.67% at the time of writing.

Add in the expense ratio of 0.35% and we're right at an even 3% for total drag, with that calculation being:

FC + RC + ER

where FC is financing cost, RC is roll cost, and ER is expense ratio.

The glaring irony here is that there would be far less drag if the assets were reversed: 90% straight EAFE stocks and 60% S&P 500 futures.

Someone smarter than me may want to check my assumptions and math here, as while I know a little more than the average person, I'm admittedly not an expert on futures, particularly for international markets.

Is NTSD a Good Investment?

So is NTSD a good investment? Maybe.

Let's talk about what I think are several salient considerations, which I've broken up into 3 sections below.

Elephant 1 – Stocks Plus More Stocks

The first big elephant in the room here is that, as I hinted at above in the risks section, while both are 90/60, NTSX and NTSD are two completely different products. NTSX uses 2 completely separate, uncorrelated asset classes in stocks and bonds, which means undeniable diversification with the sensible expectation of dampened volatility of the fund per se.

NTSD is entirely stocks, 150% of them. There's no getting around the fact that it's going to be more volatile than 100% stocks right off the bat.

Zooming out a bit to speak more generally on this point, the whole purpose of this fund family's creation – and the research from which it was based – was capital efficiency in service of asset class diversification, not just to lever up equities exposure. In that sense, NTSD frankly doesn't seem to fit with the spirit of its peers (which is fine I guess, but worth noting in my opinion). In a family photo of NTSX, NTSI, NTSE, and NTSD, NTSD is going to look out of place. It's taller and has a more aggressive bone structure.

I know I'm annoyingly repeating this distinction at this point that I already covered in the risks section above, but I think it bears repeating just to make it abundantly clear that while it shares a very similar ticker, NTSD provides a very different exposure with very different expected behavior compared to the NTSX/NTSI/NTSE family. NTSD is arguably a distant cousin.

I wasn't the only one to notice this. On WisdomTree's announcement post on Twitter for this fund, several replies were basically “Isn't this just levered global equity?”

Elephant 2 – No Emerging Markets

The other large elephant you may have noticed – but that may not be immediately obvious – is that EAFE is just developed markets, so NTSD excludes Emerging Markets entirely.

If you've read my ramblings elsewhere, you know I like some Emerging Markets for their reliably lower correlation to U.S. stocks due to their unique developmental characteristics. A fun stat I often rattle off is that when U.S. stocks finished flat for the famous Lost Decade of 2000-2009, Emerging Markets finished up 155%.

EAFE markets are inherently highly correlated with U.S. stocks, so you're getting the least amount of geographical diversification of any type of international exposure, as even global market cap weights put Emerging Markets at about 10%. Here you're getting zero. I'm not sure why WisdomTree chose to exclude them entirely.

I think that makes the product much more confusing and much less appealing, but that's just me. I would venture to guess anyone who feels comfortable buying this product probably wants some Emerging Markets in there.

It's a bit of a head scratcher for me. I don't really see why one wouldn't just use other products to create similar exposure, such as NTSX + NTSI + NTSE, unless the investor just absolutely hates bonds and Emerging Markets. So I guess I'm missing the appeal of NTSD.

I'm not seeing a clear slot for how exactly this thing would slide into well-diversified portfolios, and I'm not seeing the obvious utility of the product design like I did with NTSX. If you added bonds to your portfolio here alongside NTSD, you'd be doing so in a way that is objectively less tax-efficient than just using NTSX + NTSI. If you want to diversify outside the U.S., I'd guess you'd probably want all markets outside the U.S.

If you want Emerging Markets exposure with NTSD, you've got to add beta to your beta, which again sort of defeats the entire purpose here. And then doing so takes up more space that you can't use for a diversifier.

Not that it matters much, but it's also going to be basically impossible to resemble global market cap weights accurately, because you're starting with an immutable 3:2 ratio of US to EAFE. I can see Bogleheads being annoyed with that mathematical imprecision.

In the fund literature, WisdomTree have some nice charts about valuations, correlations, risk, returns, etc. to support the idea of international equities diversification, which we'd expect. But all those nice statistical attributes apply just as much, if not more, to Emerging Markets! Strangely, the roughly 30 pages of marketing materials basically just don't mention Emerging Markets, as if they don't even exist. Any references to diversifying outside U.S. borders – of which there are naturally many – implicitly refer solely to EAFE.

I couldn't find any official reason for why Emerging Markets are absent from this fund.

And it's not like we don't have suitable indexes that could be used. NTSD uses the MSCI EAFE Index. But we also have the MSCI All-Country World Index, which is the whole globe, we have the MSCI ACWI ex-USA Index, which is all international markets – both developed and emerging – outside the U.S., and then we even have the individual MSCI Emerging Markets Index.

Admittedly, maybe I'm also being too nitpicky. EM are only about 10% of the globe and most people probably don't consciously overweight them like I do.

Maybe they're planning to launch another variation of this allocation that is U.S. + Emerging Markets, but then that would be a weird one for all the same reasons on the other side of the same coin we've been discussing. I'm basing all this current commentary on the simple fact that NTSD is live and there's no obvious public indication that there's any plan for a variation for Emerging Markets. If anyone knows otherwise, let me know.

The only possible hint I'm aware of, which still requires some assuming, is the very last line of WisdomTree's own blog post about NTSD that says “And this is still just the beginning where our capital efficient family will go overtime.” (I think they probably meant “over time,” but I didn't want to assume more on the assumption.) That, plus the simple pattern we saw years ago of NTSX > NTSI > NTSE, is arguably suggestive.

But did anyone even ask for such a US + EAFE combination? It's puzzling to me. Maybe I'm vastly underestimating the number of people who want to avoid Emerging Markets entirely. Or maybe I'm not thinking of something obvious here; let me know in the comments.

Now let me briefly steel man the other side for a moment on this Emerging Markets conundrum.

First, NTSE's assets pale in comparison to NTSI. It's not unreasonable to think internal discussions at WisdomTree potentially concluded that investors interested in capital efficiency simply aren't interested in Emerging Markets enough to warrant their inclusion.

I'll also remind you of something that strengthens that argument further: Emerging Markets equity futures are even harder and costlier to trade than EAFE equity futures, so the efficient rolling thereof at the scale needed for an ETF would involve more friction and almost certainly a higher expense ratio than would otherwise be seen. So is it worth that greater friction and cost to be able to include Emerging Markets? Maybe WT concluded the answer is no.

Baby Elephant – The Fee

Lastly, let's briefly talk about the baby elephant – the fee – and crunch some more numbers.

0.35% seems unusually high to me purely considering what their other funds in this family cost. NTSX and NTSI have fees of 0.20% and 0.26% respectively. Put those at 60/40 and your overall fee is roughly 0.22%. NTSD costs 60% more than that, and it's just equities.

Then of course the simple, unlevered combo I mentioned earlier of VOO + VEA would only cost you 0.03% and would be more tax-efficient. So basically just to lever that up 1.5x, it costs you an extra 0.32%. That just feels high to me. And then to add insult to injury, on top of that higher fee, you've got the aforementioned worse tax treatment if we're talking about taxable space.

0.35% is higher than the other funds in the family, but I understand why it's higher: again, simply put, greater operational frictions in EAFE markets.

Speaking of which, I suppose the other baby elephants are the financing costs and roll costs discussed earlier, which amount to nontrivial drag here.

Conclusion

So I guess the optimistic interpretation is that we have a pretty well diversified global stocks fund with modest leverage, albeit lacking Emerging Markets. And honestly, maybe that simple interpretation is the appeal and I'm overthinking all this.

Proponents on Reddit are cavalierly calling this fund “1.5x VT” (VT is the Vanguard Total World Stock ETF), and while it's similar exposure, remember NTSD includes neither Emerging Markets nor small caps, while VT has both, and NTSD has a fixed relative regional allocation at a 60/40 ratio, while VT resembles true global market cap weights at any given time, for better or worse.

Is that 1.5x leverage worth the greater fee, financing costs, and roll costs? Only time will tell.

What do you think of NTSD? Let me know in the comments.
