SP Morningstar·https://www.morningstar.com 3 Top US ETFs for 2026 and Beyond | Morningstar The cheapest one is State Street SPDR Portfolio S&P 500 ETF, ticker SPYM. It charges just 2 basis points. Consequently, it performed the best over the past 10 years compared to the other S&P 500 ETFs.

If you want a simple, long-term S&P 500 index ETF, my top pick is VOO (Vanguard S&P 500 ETF).

My ranking

Why VOO: It tracks the S&P 500, has an extremely low 0.03% expense ratio, enormous assets, and is designed as a straightforward long-term core holding. Vanguard currently reports the 0.03% expense ratio.

IVV is essentially just as good. It also tracks the S&P 500 and charges 0.03%.

SPYM is interesting because its expense ratio is only 0.02%, making it technically the cheapest of these choices. State Street reports that it tracks the S&P 500 and currently has about $169 billion in assets.

I'd generally choose VOO over SPY for a buy-and-hold investor. SPY's big advantage is trading liquidity, but its 0.0945% expense ratio is substantially higher.

Bottom line

If you told me, "I want to invest in the S&P 500 for 10–30 years and don't want to overthink it," I'd pick VOO.

One important caveat: the "best" ETF can depend on whether this is a 401(k), IRA, Roth IRA, or taxable brokerage account, and on whether you're investing a lump sum or making monthly contributions. If you tell me which account you're using and roughly how much you're investing, I can recommend the best choice and explain VOO vs. IVV vs. SPYM for your situation.

If you want a simple, low-cost ETF that tracks the S&P 500, my top choice is VOO (Vanguard S&P 500 ETF).

My ranking

VOO, IVV, and SPY all track essentially the same S&P 500 index, so their investment performance is very similar before fees. The biggest practical difference is cost: VOO and IVV charge just 0.03%, while SPY is considerably more expensive.

Why I'd pick VOO: its 0.03% expense ratio is extremely low, it's highly liquid, and it is designed specifically as a long-term core holding. At that fee, you'd pay roughly $3 per year for every $10,000 invested.

IVV is effectively just as good. It also charges 0.03% and tracks the S&P 500. www.etf.comwww.ishares.com If your brokerage makes IVV easier or cheaper to buy, there's little reason to prefer VOO.

One important distinction: if by "S&P 500 index fund" you mean the best single fund for your entire portfolio, rather than specifically an S&P 500 tracker, I'd also consider a total-market or total-world ETF because the S&P 500 excludes smaller U.S. companies and international stocks.

If you tell me your age, investment horizon, and whether this is a taxable account, Roth IRA, or 401(k), I can tell you which ETF I'd choose and how I'd allocate it.

When looking for the best S&P 500 ETF, the short answer is that VOO, IVV , and SPLG are nearly identical in performance because they all track the exact same 500 companies . The differences come down to cost (expense ratio) and your specific use case.

The top choices compare as follows:

• Vanguard S&P 500 ETF (VOO): Best for long-term buy-and-hold retail investors. It features an ultra-low expense ratio of 0.03% ($3 annually per $10,000 invested) and has grown to become one of the largest ETFs in the world . Vanguard’s investor-owned structure makes it a favorite for core portfolio building.
• iShares Core S&P 500 ETF (IVV): Best institutional alternative to VOO. Managed by BlackRock, it matches VOO's ultra-low expense ratio of 0.03% and delivers virtually identical total returns, with high liquidity and efficiency.
• SPDR Portfolio S&P 500 ETF (SPLG): Best for the absolute lowest fee / smaller accounts. Formerly known as SPYM, State Street prices this fund with an even lower expense ratio of 0.02%, and a lower per-share price makes it very budget-friendly if you aren't using fractional shares.
• SPDR S&P 500 ETF Trust (SPY): Best for active traders and options. SPY is the oldest and most heavily traded S&P 500 fund, boasting an unmatched options market ecosystem . However, its expense ratio is higher at 0.0945% ($9.45 per $10,000), making it less ideal for long-term buy-and-hold investing compared to VOO or IVV.

Are you planning to use this as a long-term buy-and-hold investment or for active trading/options , and does your broker support fractional shares ? I can give you a final specific recommendation based on those details.

When looking for the best S&P 500 ETF, the short answer is that VOO, IVV , and ultra-low-cost alternatives like SPLG are practically identical in performance and holdings because they all track the exact same index . The differences come down to expense ratios (fees), fund structure , and trading goals.

The top options break down as follows:

• Vanguard S&P 500 ETF (VOO)
  • Expense Ratio: 0.03% ($3 on a $10,000 investment)
  • Best For: Long-term buy-and-hold retail investors. It is massively popular, highly trusted, and backed by Vanguard's investor-owned structure.
• iShares Core S&P 500 ETF (IVV)
  • Expense Ratio: 0.03%
  • Best For: Investors using brokerages other than Vanguard (like Fidelity or Schwab), or those looking for an identical alternative to VOO for tax-loss harvesting. It is managed by BlackRock.
• SPDR Portfolio S&P 500 ETF (SPLG)
  • Expense Ratio: 0.02% ($2 on a $10,000 investment)
  • Best For: Fee-conscious investors looking for the absolute lowest cost among major S&P 500 ETFs. (Note: State Street also manages SPY , but SPY has a higher fee of 0.09% because it is optimized for heavy day-trading and options liquidity rather than long-term holding).

To help narrow down which one makes the most sense for you, tell me:

• Which brokerage platform do you use (e.g., Vanguard, Fidelity, Schwab, Robinhood)?
• Are you planning a long-term buy-and-hold strategy or active trading/options?

If your goal is simply “own the S&P 500 for the long term at very low cost,” my top choices are:

VOO and IVV both charge just 0.03% and track the S&P 500. SPYM is now even cheaper at 0.02%, according to State Street. SPY is considerably more expensive for a long-term buy-and-hold investor, despite its enormous liquidity.

My pick: VOO

For a long-term retirement/taxable investment, I'd lean toward VOO. There's very little practical difference between VOO and IVV—their costs and underlying exposure are essentially identical. VOO has also accumulated enormous assets, making it a very established core holding.

The interesting newcomer is SPYM: at 0.02%, its annual fee is about $2 per $10,000 invested, versus $3 for VOO/IVV. That's a tiny difference, so I wouldn't switch from an existing VOO/IVV position solely to save that 0.01%.

Bottom line:
Starting from scratch → VOO.
Already own IVV → keep IVV.
Want the absolute lowest expense ratio → SPYM.
Primarily trading options → SPY.

If you tell me whether this is for a taxable brokerage, Roth IRA, traditional IRA, or 401(k), plus roughly how much you're investing, I can tell you which one I'd choose and why.

When looking for the best S&P 500 Exchange-Traded Fund (ETF), most top choices track the exact same index and yield virtually identical performance . The "best" choice comes down to your specific goals, such as absolute lowest cost, long-term buy-and-hold investing, or active options trading.

The top contenders stack up as follows:

• Vanguard S&P 500 ETF (VOO)
  • Expense Ratio: 0.03% ($3 per year for every $10,000 invested)
  • Best For: Long-term "set-and-forget" buy-and-hold investors.
  • Why it's a top pick: Backed by Vanguard’s investor-owned structure, massive scale (over $1 trillion in assets), and razor-thin fees.
• • Expense Ratio: 0.03%
  • Best For: Long-term investors looking for an exact equivalent to VOO, managed by BlackRock.
  • Why it's a top pick: It matches VOO's ultra-low cost and high liquidity, making it interchangeable for most retail portfolios.
• SPDR Portfolio S&P 500 ETF (SPYM)(formerly SPLG)
  • Expense Ratio: 0.02%
  • Best For: Cost-conscious investors and beginners needing a lower absolute share price.
  • Why it's a top pick: State Street's low-cost alternative undercuts VOO and IVV by a fraction, making it the cheapest S&P 500 ETF available.
• SPDR S&P 500 ETF Trust (SPY)
  • Expense Ratio: 0.0945%
  • Best For: Active day traders and options strategists.
  • Why it's a top pick: As the oldest and most heavily traded ETF in the world, it has unmatched liquidity and the deepest options market, though its higher fee makes it less optimal for long-term buy-and-hold.

Are you planning a long-term buy-and-hold strategy or looking to trade options , and do you have a preference for a specific brokerage platform?

If your goal is simply “buy the S&P 500 and hold it for the long term,” my default pick would be VOO (Vanguard S&P 500 ETF).

The main contenders are:

IVV currently has a 0.03% expense ratio and tracks the S&P 500 directly. www.ishares.com VOO and IVV are therefore extremely close for a buy-and-hold investor; the difference in fees is negligible.

My recommendation

🥇 VOO — best default choice

Why:

• Extremely low cost
• Tracks the S&P 500
• Huge, established fund
• Excellent for long-term investing
• No need to overthink it

IVV is essentially just as good. If your brokerage makes IVV easier or you already own it, I wouldn't sell it merely to switch to VOO.

SPY is also excellent, but its higher expense ratio makes it less attractive for a long-term investor when VOO/IVV do essentially the same job.

One important caveat: “best” depends on what you're investing for. If this is for retirement and you're building a portfolio from scratch, I'd also consider whether you actually want only the S&P 500 versus a total-U.S.-market or global ETF.

If you tell me your age, investment horizon, and whether this is a taxable account or IRA/401(k), I can give you a more tailored choice and allocation.

If your goal is a long-term, low-cost S&P 500 index ETF, the best choices are all very similar because they track the exact same index. The differences come down to fees, liquidity, and the brokerage you use.

My recommendation

For most investors:

• VOO is the default choice. It's extremely low-cost, highly liquid, and backed by Vanguard.
• If your brokerage makes IVV easier to buy, it's an equally strong option.
• If you're focused on minimizing fees as much as possible, SPLG is worth considering, though the savings versus VOO are tiny.

For example, on a $100,000 investment:

• 0.03% fee = about $30 per year
• 0.02% fee = about $20 per year

That's only about $10 annually, so factors like your brokerage, automatic investing features, and convenience often matter more than the last basis point.

If you're investing for retirement and simply want to "buy and hold" for decades, VOO is the choice I'd recommend for most people.

If you tell me:

• your age,
• whether this is in a 401(k), IRA, Roth IRA, or taxable brokerage account, and
• how much you plan to invest each month,

I can suggest the ETF that best fits your specific situation.

When choosing an S&P 500 ETF, the short answer is that VOO, IVV , and SPYM are virtually identical in performance because they all track the exact same index. The right choice comes down to your expense ratio (fees) and how you plan to trade.

The top S&P 500 ETFs compare as follows:

• • Expense Ratio: 0.03% ($3 annually per $10,000 invested)
  • Best For: Long-term buy-and-hold retail investors
  • Why it stands out: It is one of the largest ETFs in the world, backed by Vanguard's investor-owned structure. It handles dividends and structural tracking with maximum efficiency for long-term compounding.
• iShares Core S&P 500 ETF (IVV) (managed by BlackRock)
  • Expense Ratio: 0.03%
  • Best For: Long-term investors or taxable accounts
  • Why it stands out: It is a direct peer to VOO with the same low cost. Some investors prefer IVV for secondary portfolio pairing or specific tax-loss harvesting strategies alongside Vanguard funds.
• SPDR Portfolio S&P 500 ETF (SPYM) (formerly SPLG)
  • Expense Ratio: 0.02%
  • Best For: Fee-conscious core investors looking to shave off every single basis point
  • Why it stands out: State Street's lower-cost sibling to SPY. It undercuts VOO and IVV by a microscopic 0.01%, making it technically the cheapest mainstream S&P 500 ETF available.
• SPDR S&P 500 ETF Trust (SPY)
  • Expense Ratio: 0.0945% ($9.45 annually per $10,000 invested)
  • Best For: Active traders and options users
  • Why it stands out: SPY is the oldest and most heavily traded S&P 500 fund, boasting the deepest options liquidity in the world. However, it charges triple the annual fee of VOO or IVV, making it less ideal for passive, long-term holding.

Summary Recommendation

• For a standard long-term portfolio , go with VOO or IVV (or check which one your brokerage offers commission-free).
• If you want the absolute lowest headline fee for an ETF, look at SPYM.
• Avoid SPY unless you plan on actively day-trading or trading options.

Are you planning to hold this in a taxable brokerage account or a retirement account (like an IRA) , and which brokerage platform are you using?
