What exactly is the S&P 500?
A market-cap-weighted index of 500 large US stocks selected by Standard & Poor's. Launched in 1957, it's the benchmark of the US stock market, covering about 80% of total US-listed market cap. It's the yardstick for evaluating fund managers, and index ETFs like VOO, IVV, and SPY track it. 'Investing in the S&P 500' means diversifying across 500 large US stocks by market-cap weight.
Why does Warren Buffett recommend an S&P 500 index fund?
Buffett holds that most individual investors, net of costs, can't beat the market average. So he says the most sensible strategy is to track the average via a low-fee S&P 500 index fund. Famously, his will instructs that 90% of the assets left to his wife be placed in a low-cost S&P 500 index fund. Note this is a long-term diversification principle, not a short-term return guarantee.
VOO, IVV, or SPY — which is better?
All three track the same S&P 500 index, so returns are nearly identical. The difference is fees: VOO (Vanguard) and IVV (BlackRock) charge 0.03%, while SPY (State Street) charges 0.0945% — about 3× more. For long-term accumulation, lower-cost VOO or IVV wins; SPY has the highest volume, suiting short-term trading and options. For buy-and-hold, VOO/IVV is the usual choice.
Isn't a 30%+ top-10 weight strange?
The S&P 500 is also cap-weighted, so as big-tech caps grew, top concentration kept rising. The top 10 holdings — once in the low 20s percent — have climbed to roughly 33-36%. So even diversified across 500 names, it's actually quite concentrated in a few big-tech stocks. Hence the critique that 'the S&P 500 is now a big-tech bet,' and an equal-weight S&P 500 ETF (RSP) is one alternative to reduce concentration.
As of when are these weights?
The weight and sector data are estimates from public sources. Actual weights shift daily with market prices, and constituents change via quarterly rebalancing plus ad-hoc M&A/delisting changes. Per-stock prices and daily change use unofficial Yahoo Finance data refreshed every 5 minutes but may lag 15-20 minutes — for exact live composition, check S&P Dow Jones or the issuer's (e.g., Vanguard) official disclosures.
What is the S&P 500's historical return?
Since its 1957 launch, it has returned about 10% annually (nominal) with dividends reinvested. After subtracting inflation, the real return is around 7% per year. But that's a long-run average only — in any given year it might rise 30%+ or fall sharply, like −38% in 2008. It trended up long-term through the dot-com bust, the financial crisis, and COVID, yet past performance does not guarantee future returns.
Does the S&P 500 pay dividends?
S&P 500 ETFs like VOO, IVV, and SPY pay quarterly dividends, yielding about 1.2-1.5%. That's higher than the NASDAQ-100 (~0.5-0.7%) because it includes dividend-paying traditional industries — financials, healthcare, utilities. Still, it's lower than SCHD (~3.5%) or high-dividend ETFs, so the S&P 500 is best viewed as a market-representative index balancing dividends and growth.
How is the S&P 500 taxed for a Korean resident?
Buying US-listed VOO/IVV/SPY directly, capital gains are taxed 22% (after a ₩2.5M annual deduction, filed each May), and dividends are withheld 15% in the US. Korea-listed S&P 500 ETFs (e.g., TIGER US S&P500, KODEX US S&P500) face 15.4% dividend-income tax on trading and distribution gains, and can be held in ISA/pension accounts for tax savings. Your effective tax varies greatly by whether you use tax-advantaged accounts.
How do Korea-listed S&P 500 ETFs differ from US-listed VOO?
They track the same index but differ in: ① tax (US direct = 22% capital gains; Korea-listed = 15.4% dividend-income), ② FX conversion (Korea-listed buys in won), ③ ISA/pension eligibility (Korea-listed only), and ④ fees (Korea-listed are usually slightly higher). Hedged (H) versions remove FX swings but cost hedging fees; unhedged (UH) pass FX through. Korea-listed wins for tax-advantaged accounts or skipping FX; US-listed wins on lower fees and directly holding dollar assets.
S&P 500 or total-world stocks (VT) — which is better?
The S&P 500 (VOO) concentrates on 500 large US stocks, while VT (total world) spreads across ~9,000 stocks including developed and emerging markets outside the US. Over the past decade-plus, strong US tech let the S&P 500 outpace VT, but the now-oversized US weight is a concentration risk. If you trust continued US dominance, the S&P 500; if you want country diversification, VT. Holding both to balance US concentration and global diversification is also common.
