16 Low-Cost ETFs to Buy

SoFi Select 500 ETF

• Type: Large-cap growth
• Assets under management: $499.6 million
• Expenses: 0.00%, or $0 annually for every $10,000 invested

The SoFi Select 500 ETF (SFY, $15.74) is as cheap as it gets. It costs absolutely nothing to tap into this portfolio of 500 large U.S. stocks …

… for now.

The name might lead a few investors to think it's an S&P 500 ETF; not so. Instead, this index fund tracks the Solactive SoFi US 500 Growth Index, which is made up of 500 of the largest U.S.-listed stocks while factoring in three fundamental metrics: trailing 12-month sales growth, trailing 12-month earnings per share (EPS) growth, and analysts' consensus 12-month forward-looking EPS growth estimates.

Despite the quality filters, the top 10 stocks aren't dissimilar from other large-cap index funds: Amazon.com (AMZN) is tops at 6%, followed by Apple (AAPL, 5%), Microsoft (MSFT, 5%) and Tesla (TSLA, 3%). Sector holdings are pretty standard, too – SFY is heaviest in tech stocks (24%), followed by consumer discretionary (15%), healthcare (11%) and financial services (11%), though these and the individual holdings can obviously change over time.

One vital note about SFY that can also serve as an educational point for many of even the best ETFs: SoFi has no expenses on a net basis – it charges 0.19% in gross fees, but a temporary 0.19% fee waiver is what knocks that fee to zero. The fee waiver was only guaranteed through Dec. 30, 2022, but it persisted as of SoFi's March 31, 2023, fact sheet, and there's no indication that waiver will disappear anytime soon.

Translation: If you do buy SFY, keep a close eye on that waiver. And whenever you're examining low-cost ETFs, determine whether the net expense ratio includes a fee waiver – because that ETF might not always sport that low, low price.

The good news? Most of the rest of the funds we'll cover have naturally low fees – no fee waiver necessary!

Note: SFY is not the only no-cost large-cap growth ETF. The BNY Mellon U.S. Large Cap Core Equity ETF (BKLC) also provides large-cap growth exposure for precisely zero fees.

* Includes 0.19% fee waiver.

Vanguard Total Stock Market ETF

• Type: Large-cap blend
• Assets under management: $310.3 billion
• Expenses: 0.03%

There are no asterisks with the Vanguard Total Stock Market ETF (VTI, $220.94) – it was dirt-cheap yesterday, it's dirt-cheap today, and it's going to be dirt-cheap for the foreseeable future.

Vanguard ETFs are, on the whole, among the cheapest in the business. But VTI is a particularly noteworthy jewel, providing access to nearly 4,000 stocks for a mere $3 annually for every $10,000 invested.

VTI is, as the name suggests, a "total stock market" fund, holding not just large caps like an S&P 500 fund, but equities of every size. It's market capitalization-weighted, so big stocks still dominate at more than 70% of assets, but you're still getting a nearly 20% weighting in mid-cap stocks and another 10% or so in smalls.

Effectively, this is an entire stock portfolio in one low-cost ETF.

It's not a perfectly balanced portfolio, of course. In addition to the oversized weighting in heavyweights, VTI features big clumps of technology (30%), consumer discretionary stocks (14%) and healthcare (13%), but next to no assets in sectors like materials (2%) and communication services (2%). And stocks like Apple and Microsoft have much more sway than the tinier names in the portfolio.

Still, VTI – and its mutual fund counterpart, the Vanguard Total Stock Market Index Fund Admiral Shares (VTSAX)—is simple, cheap and diversified, making it a wildly popular fund. Indeed, VTI and VTSAX combined boast $1.3 trillion in assets.

Fidelity Sector ETFs

• Type: Sector
• Expenses: 0.084%

OK. We're actually squishing 11 funds into this entry.

While firms like Vanguard and Schwab have made a name for themselves by providing low-cost ETFs, Fidelity is no slouch, either. Numerous Fidelity index funds are near the bottom of their categories in fees … and in the case of their sector ETFs, they're the cheapest you can get.

Here are Fidelity's 11 sector funds, all of which trade at just 0.084%, or $8.40 annually on every $10,000 invested:

· Fidelity MSCI Communication Services Index ETF (FCOM, $40.45)

· Fidelity MSCI Consumer Discretionary Index ETF (FDIS, $74.20)

· Fidelity MSCI Consumer Staples Index ETF (FSTA, $45.72)

· Fidelity MSCI Energy Index ETF (FENY, $22.24)

· Fidelity MSCI Financials Index ETF (FNCL, $47.39)

· Fidelity MSCI Health Care Index ETF (FHLC, $62.68)

· Fidelity MSCI Industrials Index ETF (FIDU, $56.88)

· Fidelity MSCI Information Technology Index ETF (FTEC, $130.46)

· Fidelity MSCI Materials Index ETF (FMAT, $46.85)

· Fidelity MSCI Real Estate Index ETF (FREL, $25.34)

· Fidelity MSCI Utilities Index ETF (FUTY, $42.53)

Fidelity's sector ETFs are based off MSCI indexes that are much more broad-based than SPDR's lineup – the gold standard of sector funds. Whereas the SPDR sector ETFs only hold stocks within the S&P 500 (and thus usually only hold a few dozen stocks each), Fidelity sector ETF holdings get up into the hundreds. 

Fidelity MSCI Information Technology Index ETF, for instance, holds 360 stocks at present, even providing some (10%) mid-cap exposure. That said, overweights are every bit as common as they are in the SPDR sector ETFs; FTEC, for instance, has a 22% weighting in Apple and another 19% in Microsoft, meaning a mere two stocks are responsible for 40% of the ETF's performance.

That's pretty standard fare, however, and it comes in a cheaper package than any competitor provides.

Gabelli Automation ETF

• Type: Thematic (Technology)
• Assets under management: $4.9 million
• Expenses: 0.00%*

 A "thematic fund" invests in a broader theme – say, robotics or artificial intelligence ETFs – that can span several sectors. Artificial intelligence, for instance, includes not just technology companies, but also communication services stocks, consumer discretionary, and more.

Because their rules tend to be a little more complex than a basic sector fund, thematic index funds tend to be more expensive. And if you're looking at an actively managed thematic fund … well, you can expect that to be a pricey puppy.

But – for now – Gabelli Automation ETF (GAST, $23.25) charges nothing.

The Gabelli Automation ETF is an actively managed thematic ETF investing in companies that are either involved somehow in automation technology – be it hardware, software, even processes – or use them to make their own businesses more productive. 

Industrial stocks such as Rockwell Automation (ROK) and Emerson Electric (EMR) make up the meat of this fund, at 54% of assets. Technology also takes up a thick 27% of AUM, with sprinklings of communication, materials and other sectors.

Under normal circumstances, Gabelli charges a hefty 0.90% in management expenses. However, the company said it would completely waive that fee on the first $25 million in net assets for one year from the commencement of the fund's operations. 

Thing is, inception was in early January 2022, so that year has passed, yet Gabelli still lists a 0.00% net expense ratio. But be on alert – should you buy GAST, you could go from paying nothing in fees to 0.90%, which is far more expensive than your average ETF and pricier than many thematic funds.

* Includes 0.90% fee waiver.

Note: Gabelli has another zero-fee thematic, the Commercial Aerospace and Defense ETF (GCAD).

SPDR Portfolio Developed World ex-US ETF

• Type: International equity
• Assets under management: $16.2 billion
• Expenses: 0.04%

As a general rule, funds investing in international stocks tend to be pricier than those that buy U.S. stocks. And indeed, the cheapest international stock ETF is more expensive than numerous low-cost ETFs with a focus purely on U.S. stock … but not by much.

The SPDR Portfolio Developed World ex-US ETF (SPDW, $32.63) provides exposure to stocks from roughly 25 other countries for the low, low price of just $4 annually for every $10,000 invested.

SPDW is a vast fund of roughly 2,500 stocks from developed and emerging markets alike. Japan is tops at the moment, with more than 21% of assets under management dedicated to the country's stocks. It's followed by the U.K. (12%), Canada (10%), France (9%) and Switzerland (8%).

The fund is loaded with European blue-chip dividend stocks including Nestle (NSRGY), Novo Nordisk (NVO) and Roche (RHHBY). As a result, SPDW has a high yield of 2.9% that beats most basic U.S. stock funds right now.

BNY Mellon Core Bond ETF

• Type: Total bond
• Assets under management: $440.4 million
• Expenses: 0.00%

Our list of low-cost ETFs also extends into the bond world – indeed, you can broad fixed-income exposure for zero fees with one bond ETF.

The BNY Mellon Core Bond ETF (BKAG, $41.80) is an indexed bond fund that holds nearly 2,800 different investment-grade fixed-income issues. You get a decent spread – more than 40% of the holdings are U.S. Treasuries, another 27% are fixed-rate agency bonds, and the rest are corporate bonds scattered across various industries.

The average duration of BKAG's portfolio is 6.4 years, which means that a 1% increase in interest rates should cause a 6.4% decline in the ETF's price, and vice versa. That's virtually identical to the duration of the Bloomberg U.S. Aggregate Bond Index right now, yet BKAG offers up 4.2% in SEC yield to the Agg's 4.0% currently.

Like with most other broad bond ETFs, BKAG doesn't offer exposure to some bond classes, such as junk and municipals. But you can always complement BKAG's basic bond exposure with a couple more targeted funds.
