WealthWorks Editorial Team
Intelligent Investing • January 31, 2026You know you should invest. You know which accounts to use. Now: what do you actually buy?
This is where most people get overwhelmed—and unnecessarily so.
This guide breaks down the major investment vehicles: stocks, bonds, ETFs, mutual funds, index funds, and REITs. You'll learn what each is, how they work, and—most importantly—which ones you should use.
Spoiler: for most people, the answer is simpler than you think.

ETFs vs Mutual Funds: What's the Difference?
Both are collections of stocks/bonds, but they differ in structure, costs, and tax efficiency.
ETF vs Mutual Fund
Both index ETFs and index mutual funds track the same markets. The differences are minor:
Feature
ETF
Mutual Fund
Trading
Throughout trading day (like stocks)
Once per day at 4PM ET
Minimum Investment
1 share ($50-500 typically)
$1,000-3,000 minimum (varies)
Fees
0.03-0.20% (lower)
0.04-0.50% (slightly higher)
Tax Efficiency
More efficient (fewer capital gains)
Less efficient
Automatic Investment
Not available
Yes (dollar-based)
The Bottom Line
For most investors, the differences don't matter. Choose based on: ETF if you want lower minimums and slightly lower fees. Mutual Fund if you want to automate dollar-based contributions. Either is fine—just pick one and move forward.
The Modern Consensus
ETFs have largely won the debate. Lower costs, better tax efficiency, and trade flexibility make them superior for most investors. Only exception: some employer 401k plans only offer mutual funds (still fine—focus on low-cost options).
Index Funds: The 90/10 Solution
Index funds track a market index (S&P 500, total stock market, etc.) instead of trying to beat it. This simple approach outperforms 90% of actively managed funds over 20+ years.
Index Fund Examples
These three funds form the foundation of the “three-fund portfolio” — a simple, effective strategy for most investors:
VTSAX / VTI
VanguardTotal U.S. Stock Market
3,600+ companies
0.04%
VTSAX: $3,000 / VTI: 1 share (~$250)
Owns essentially every publicly traded U.S. company. Complete U.S. market exposure.
VTIAX / VXUS
VanguardTotal International Stock Market
8,000+ companies
0.11%
VTIAX: $3,000 / VXUS: 1 share (~$70)
Owns stocks from developed and emerging markets outside the U.S. Geographic diversification.
VBTLX / BND
VanguardTotal U.S. Bond Market
10,000+ bonds
0.05%
VBTLX: $3,000 / BND: 1 share (~$75)
Government and corporate bonds. Lower volatility than stocks, lower expected returns.
The Three-Fund Portfolio
60% U.S. stocks + 30% International stocks + 10% Bonds = instant global diversification in three funds. Simple, effective, low-cost.
Bonds: The Stability Anchor
Bonds are loans you make to governments or corporations. They pay interest and return principal at maturity. Lower returns than stocks, but more stable.
Bond Types
Treasury Bonds
U.S. Government
Lowest (backed by government)
3-5% (varies with term)
Safety, predictable income
Corporate Bonds
Private Companies
Medium (depends on company)
4-7% (varies with credit rating)
Higher yield than Treasuries
Municipal Bonds
State/Local Governments
Low-Medium
2-4% (tax-free in your state)
High earners seeking tax-free income
When to Use Bonds
Bonds are for money you'll need in 3-10 years (house down payment, car replacement) or to reduce portfolio volatility near retirement (60/40 or 70/30 stock/bond split). If you're under 40 with 20+ years until retirement, you can skip bonds entirely and go 100% stocks.
REITs: Real Estate Without the Hassle
Real Estate Investment Trusts (REITs) let you invest in real estate without buying property directly. They own and manage income-generating properties (apartments, offices, warehouses, malls).
Real Estate Investment Trusts (REITs)
What is a REIT?
A company that owns, operates, or finances income-producing real estate. By law, REITs must pay out 90%+ of taxable income as dividends to shareholders.
Pros
• Diversification beyond stocks/bonds
• High dividend yields (3-5%)
• Liquid (trade like stocks)
• No landlord responsibilities
Cons
• Dividends taxed as ordinary income
• Interest rate sensitive
• Lower long-term returns than stocks
• Correlation with stock market
Recommendation
REITs are optional. Total stock market index already includes some real estate exposure. If you want more, allocate 5-10% of portfolio. Keep in tax-advantaged accounts due to dividend taxation.
Active vs Passive Investing
Active vs Passive Management
Active Management
Fund manager picks stocks trying to beat the market
0.5-2.0% annually
90% fail to beat market over 20 years
Low (manager does work)
PRGFX (T. Rowe Price Growth)
Passive (Index) Management
Fund tracks entire market index
0.03-0.20% annually
Matches market (beats 90% of active funds)
Minimal (set and forget)
VTSAX (Vanguard Total Stock)
The Data is Clear: Passive Wins
Over 20 years, 90% of actively managed funds underperform their index benchmark after fees. The few that beat it rarely do so consistently.
For most investors, low-cost index funds are the obvious choice. Don't pay 10-50x higher fees for worse performance.
The Data is Clear
Over 15 years, 90% of actively managed funds underperform their benchmark index after fees. Over 20 years, it's closer to 95%.
Translation: unless you're a professional investor with time to research, stick with low-cost index funds.
The Simple Portfolio: What to Actually Buy
The Three-Fund Portfolio (Beginner to Advanced)
1. Total US Stock Market (VTI, VTSAX): 60-80%
2. Total International Stock Market (VXUS, VTIAX): 10-30%
3. Total US Bond Market (BND, VBTLX): 10-30%
This covers the entire investable world with just three funds. Adjust percentages based on age and risk tolerance.
The One-Fund Portfolio (Ultra Simple)
Target-Date Fund (e.g., “Vanguard Target Retirement 2055”): 100%
One fund, automatically rebalanced, adjusts risk over time as you near retirement. Perfect for hands-off investors.
The Bottom Line
You don't need to be an expert to invest successfully.
Low-cost index funds (VTI, VOO, target-date funds) give you instant diversification across hundreds of companies, with returns that beat 90% of professionals over time—all for under 0.1% annual fees.
Simplicity wins. Low costs win. Time in market wins.
The hardest part is doing nothing once you've invested.
