Key Takeaways
At the highest level, investments fall into a few categories. You don't need all of them, and for most investors, a two- or three-category portfolio is more than enough.
Stocks (equities) represent partial ownership of a company. You profit when the company's value grows and, sometimes, through dividends. Historically the highest-returning major asset class over long periods, but also the most volatile.
Bonds (fixed income) represent loans you make to governments, municipalities, or corporations. You receive regular interest and your principal back at maturity, assuming the borrower doesn't default. Lower returns than stocks, but much lower volatility — they reduce portfolio risk when paired with equities.
Cash and equivalents — savings accounts, money market funds, short-term Treasuries. Principal is essentially safe in nominal terms, but inflation erodes purchasing power. Useful for emergency funds and money you'll need within 1–2 years.
Real estate — direct ownership of property, or shares in REITs (Real Estate Investment Trusts) that hold real estate portfolios. Provides income (rent) and price appreciation. Often treated as part of a diversified portfolio, though many Americans already have significant real-estate exposure through their home.
Alternatives — commodities, private equity, hedge funds, crypto. Can provide diversification but add complexity, cost, and in many cases poor risk-adjusted returns. Most investors don't need them.
You can own investments directly (individual stocks, individual bonds) or through pooled vehicles (mutual funds, ETFs). For almost all individual investors, pooled is the right answer:
The exception is when you have a specific goal that requires individual securities — for example, a bond ladder for known future cash needs, or company stock you received as compensation.
Passive funds try to match a market index (S&P 500, Total Stock Market, aggregate bond index). They have low fees and deliver the market's return, by definition minus a small expense.
Active funds try to beat the market through stock-picking or market-timing. In theory this could outperform. In practice, over 10- and 20-year periods, about 80% of active funds underperform their index after fees. There are a few durable active managers, but identifying them in advance is extremely difficult.
For most investors, a passive core portfolio is the default and active is the exception.
Many serious investors hold just three or four funds:
Everything else is refinement. The "three-fund portfolio" has produced returns roughly equivalent to professionally managed portfolios over decades, at a fraction of the cost.
Horizons doesn't track individual securities — it tracks aggregate asset values with associated strategies. That's enough for forecasting. The Connected Accounts feature can pull balances from brokerages and banks so your totals stay accurate without manual updates.
