For decades, the standard advice for retail investors has been simple: buy a mix of stocks and bonds, perhaps with a few shares of well-known companies. The stock market was the primary engine of wealth creation. But that picture is changing, and the shift has big implications for how everyday investors think about opportunity.
Private companies—those not listed on public exchanges—are now capturing a growing share of the economy's growth before they ever go public. As a result, the traditional 60/40 portfolio (60% stocks, 40% bonds) may no longer offer the balance it once did. Investors who ignore private markets could be missing some of the most significant opportunities of the 21st century.
Public markets are shrinking
The number of publicly traded companies in the U.S. has declined significantly over the past two decades. In the late 1990s, there were over 7,000 listed companies. Today, that number is closer to 4,000. Meanwhile, private companies are staying private longer, and many of the most innovative firms—think of the biggest names in tech and biotech—are choosing to raise capital from private investors rather than through an initial public offering (IPO).
This trend means that much of the value creation in the economy now happens behind closed doors. By the time a company lists on a stock exchange, a large portion of its growth may already be priced in. For retail investors who only have access to public markets, that can mean missing out on the early-stage gains that institutional investors have long enjoyed.
Powerlaw Corp. (Nasdaq: PWRL) is one company focused on helping bridge this gap. The firm provides tools and strategies that allow everyday investors to gain exposure to private markets, including through secondaries and other structures. As Powerlaw Corp's approach to secondaries shows, there are ways to tap into pre-IPO value creation without needing to be a venture capital firm.
Why private markets matter more now
The shift toward private markets is not just a temporary trend. It reflects deeper structural changes in the economy. Companies can now access large amounts of capital from private equity, venture capital, and other institutional investors without the regulatory burdens and quarterly earnings pressure that come with being public. That flexibility allows them to focus on long-term growth, but it also means that the public markets are left with a smaller and often less dynamic set of companies.
For retail investors, this creates a challenge. The traditional advice to buy a diversified portfolio of public stocks and bonds may no longer capture the full range of growth in the economy. As private markets open to more investors, understanding how to access them—and the risks involved—becomes increasingly important.
Powerlaw Corp. is one of a growing number of firms working to democratize access to private investments. The company's name references the "power law" distribution that often characterizes returns in venture capital and private equity, where a small number of investments generate the majority of returns. By providing tools to build portfolios that account for this dynamic, Powerlaw aims to help retail investors participate in the kind of growth that has historically been reserved for institutions.
What it means for investors
For the average investor, the takeaway is not that stocks and bonds are obsolete. Rather, it is that the investing landscape has evolved, and the tools and strategies that worked in the past may need to be updated. A portfolio that only includes public stocks and bonds may be missing a significant part of the economy's growth engine.
That said, private markets come with their own risks. Investments are often illiquid, meaning you cannot sell them easily. Valuations can be less transparent, and the due diligence required is often greater. For these reasons, it is important to approach private market investing with caution and to understand the specific products and platforms you are using.
Powerlaw Corp. offers one pathway, but it is not the only one. Investors should also consider how private market exposure fits into their overall portfolio and risk tolerance. As Powerlaw Corp's insights on building a portfolio for a power-law market suggest, the key is to think about diversification not just across asset classes, but across stages of company growth.
The bottom line: public markets are no longer the only game in town. For investors who want to capture the full range of economic growth, private markets are becoming an essential piece of the puzzle. The question is no longer whether to look beyond stocks and bonds, but how to do so wisely.
