Is TNA a Good Investment? The Case For and Against (2026)

TNA seeks 300% of the Russell 2000's DAILY return using total-return swaps and cash collateral. The leverage resets each day, so over multiple days the return compounds and can diverge sharply from 3x the index, an effect amplified by small-cap volatility. At roughly 1.05% it costs far more than a plain small-cap ETF and is built for short-term tactical use.

Largest holdings (approximate as of mid-2026; verify on Direxion's fund page):

TNA is a leveraged ETF from Direxion that aims to deliver three times the DAILY return of the Russell 2000, the benchmark for US small-cap stocks. A 1% up day for the index targets roughly 3% for TNA, and down days are magnified the same way. It gets there with index swaps and cash collateral, not by holding all 2,000 stocks. Because the leverage resets daily, holding TNA for weeks does not give you 3x the index's longer-run return, and small-cap volatility makes that decay especially pronounced. It is a short-term trading tool, and it is far pricier than a plain small-cap ETF.

In its favour: it gives you Russell 2000 Index (3x daily leveraged exposure) exposure in one ticker at a ~1.05% expense ratio, which is simple to hold and cheap to own.

• Cost vs alternatives: ~1.05% is the fee; compare it to funds tracking a similar index.
• Concentration: check how much of TNA sits in its largest holdings (SWAP, CASH, IWM).
• Overlap: if you already own a broad-market fund, you may already hold much of this.
• Tracking scope: TNA only gives you Russell 2000 Index (3x daily leveraged exposure); it will not capture what sits outside that index.

“Diversified” is the word every index fund uses and it hides a wide range. The number that actually matters is how much of the fund sits in its largest positions, because that is the part that drives the return. In TNA, the three largest positions are about 226% of the fund and the 3 largest are about 226%, with the single biggest at roughly 200%. Those are approximate weights as of mid-2026, and because this is the published top 3 rather than the full book, treat 226% as a floor on concentration rather than the whole picture. Verify with Direxion.

That is a concentrated fund. Most of what you own moves with a small number of companies, so TNA behaves much more like a bet on those names than the word "index" suggests. That can be exactly what you want, as long as it is what you meant to buy.

This is also the number that decides whether TNA adds diversification to your portfolio rather than to a portfolio in the abstract. A fund can be well spread on its own and still concentrate you further, if its largest holdings are names you already own directly or through another fund. That is a question about your account rather than about TNA, and it is the one worth answering before you buy.

A fund is defined as much by what it leaves out as by what it holds, and the exclusions are rarely on the marketing page. TNA tracks Russell 2000 Index (3x daily leveraged exposure), so anything outside that index is simply absent from your portfolio no matter how much of the fund you own.

In practice that means checking three gaps. Whether the geography you want is covered, since a US index holds no international companies and a developed-markets index holds no emerging ones. Whether the size band you want is covered, because a large-cap index excludes the smaller companies some investors specifically want exposure to. And whether the asset class you want is covered at all, since an equity fund holds no bonds and gives you nothing to rebalance against in a drawdown.

None of these are faults. They are the fund doing exactly what it says. The mistake is assuming that owning a diversified fund means being diversified, when it means being diversified within one index.

Being specific about this is more useful than another paragraph on why it might be right.

• You already own most of it. If a broad-market fund you hold already contains SWAP, CASH, IWM at meaningful weight, adding TNA mostly increases your exposure to the same companies while adding a second fee. That is the single most common way people accidentally concentrate.
• You want the exposure for a short horizon. An index fund is a way to own an asset class over years. Over months it is simply the index, with all of the index's volatility and none of the compounding that makes holding it worthwhile.
• You need income you can rely on. Distributions from an equity index fund vary with what the underlying companies pay, so they are not a schedule you can plan around the way a bond ladder is.
• A cheaper fund tracks the same thing. Where two funds follow a similar index, the difference in expense ratio is one of the few advantages available to you without taking extra risk. Compare before assuming ~1.05% is competitive.

The useful question is rarely “will TNA go up?” It is “does this exposure fit my plan, at a cost I am happy with, without doubling up on what I already own?” Walnut connects your real brokerage so you can see exactly how TNA would overlap with your current holdings, analyze it by chatting through Claude or ChatGPT, and place any trade yourself. You stay in control.

The bottom line: TNA is a low-cost core building block for Russell 2000 Index (3x daily leveraged exposure) exposure, not a tactical bet on a single name. If you want Russell 2000 Index (3x daily leveraged exposure) exposure and the ~1.05% fee is competitive for you, it does its job well. If you already own that exposure through another fund, adding it mostly doubles a fee without adding diversification. Decide from your goal and your existing holdings, not from where the market sat last week. Walnut is not an investment adviser.
