The Universal, and Flawed, Logic of the Portfolio
There’s a certain intellectual tidiness to the portfolio model. It’s a framework built on logic, diversification, and the cold, hard math of risk management. It’s so compelling, in fact, that some are now attempting to export it beyond the stock market and into the messy realm of human connection. Andrew "Boz" Bosworth, the CTO of Meta, recently advised treating our relationships like a stock portfolio: diversify wisely, invest intentionally, and don't panic during market dips.
It’s an elegant concept. "Imagine each person in your life as a publicly traded security," he wrote. The influence someone has on you should be proportional to your emotional investment in them. A stranger’s insult should be like a stock you don’t own crashing—irrelevant.
On its face, this is the ultimate data-driven approach to life. But while Silicon Valley is busy trying to financialize our feelings, professional fund managers from Mumbai to Oregon are grappling with the often-brutal reality of what happens when portfolio theory collides with the real world. Their stories offer a far more useful lesson in the limits of any single model. One is a case study in rational expansion, the other a cautionary tale of over-concentration. Together, they reveal the profound difference between a neat theory and its chaotic application.
The Geographic Imperative
For years, the dominant narrative for Indian investors has been to bet on India. It’s an economy with undeniable momentum. But a recent masterclass in Mumbai, summarized by the headline Go global with investments or lose out: Top experts share simple secrets to world investing, suggests a critical evolution in that thinking. The core message from top fund managers was unambiguous: limiting your investments to a single country, even a high-growth one, is no longer investing. It’s speculation.
Saurabh Mukherjea of Marcellus Investment Managers presented the data with clinical precision. The correlation between the Indian and American stock markets has, in his words, "utterly broken" over the last 15 years. This isn’t just an academic observation; it’s the mathematical foundation for a powerful diversification strategy. When one market zigs, the other is likely to zag, smoothing out portfolio returns over time. His proposed allocation for an Indian investor—60% in India, 40% in dollar-based assets—is a direct translation of this low-correlation data into an actionable plan.
But the most compelling part of his argument was a piece of second-order thinking. If you want to profit from India’s economic development, where should you invest? The obvious answer is the Indian stock market. The correct answer, he argued, might be the New York Stock Exchange. “If you want to capture the upside from India’s growth,” Mukherjea stated, “necessarily you have to go and invest in companies outside India, such as Apple, such as Microsoft.” These companies, he points out, generate more revenue from Indian consumers than almost any single Indian-listed company does.
This is the kind of insight that separates robust analysis from simple cheerleading. It requires looking past national indexes to the underlying flow of capital. The rise of GIFT City, India’s new international financial hub, is the structural response to this mathematical reality. Firms like DSP and PPFAS are now launching retail funds and alternative investments (AIFs) that give everyday investors direct access to global assets, from US tech giants to specialized sectors like gold miners, which are virtually nonexistent in India. Is this just about finding new opportunities, or is it a tacit admission that the best way to play the Indian growth story is through a global lens?
The Gravity of Over-Allocation
At the exact same time that Indian investors are being urged to diversify outward, the Oregon Public Employee Retirement System (PERS) is providing a textbook case on the dangers of failing to diversify inward. The state's $97 billion pension fund is now actively shrinking its exposure to private equity, an asset class it had allowed to balloon to a dangerously high concentration.
The numbers tell a story of ignored guardrails. The Oregon Investment Council set its own target for private equity allocation at 20% back in 2013. Yet the fund’s actual exposure crept up past 21% in 2014 and eventually peaked at nearly 28% of the entire portfolio earlier this year. To be more exact, reports like the Oregon Treasury reducing public pension investments in private equity • Oregon Capital Chronicle put the high at 28.1%. That’s a deviation of over 40% from their own strategic target and roughly double the national average for state pension funds. This isn't a minor tactical shift; it's a fundamental breakdown in portfolio discipline.
This over-allocation is like a blackjack player who starts with a clear strategy but then, after a few winning hands, abandons it to bet bigger and bigger on the same outcome. For a while, it works. But the risk accumulates silently until a market shift makes it painfully visible. State Treasurer Elizabeth Steiner is now overseeing the slow, deliberate process of unwinding this position, aiming to get back to 25% by the end of 2025 and eventually return to the original 20% target. This involves selling off investments and redirecting profits, a process that can be difficult and costly in the illiquid world of private equity.
I've looked at dozens of state pension fund filings over the years, and a sustained deviation of this magnitude from a stated strategic target is a significant anomaly. It signals a deep-seated conviction that the asset class was a can't-lose proposition, a belief that ignored the foundational principle of diversification. The fund is now course-correcting, but the question remains: what was the opportunity cost of having nearly $26 billion (at its peak) tied up in an over-concentrated, opaque asset class while ignoring their own risk parameters?
This brings us back to Bosworth’s emotional portfolio. The logic of diversification and risk management is pristine on paper. But Oregon’s struggle shows how hard it is to stick to that logic, even for seasoned professionals managing billions of dollars. The temptation of a hot asset class, the fear of missing out, and the slow creep of concentration risk are powerful forces. If a state pension fund can get it this wrong with transparent targets and consultants, what hope does an individual have in applying this same rigid logic to the unquantifiable chaos of human relationships? What is the beta of a lifelong friendship? What’s the appropriate risk-adjusted return on a marriage? The metaphor collapses under the weight of its own flawed premise.
The Map Is Not the Territory
The principles of portfolio management are an incredibly powerful abstraction for managing capital. They provide a map—a logical, data-driven guide to navigating the unpredictable territory of financial markets. The push for global investing in India is a smart reading of that map. The painful correction in Oregon is the consequence of ignoring it.
But Andrew Bosworth’s advice to apply this map to our emotional lives is a profound category error. It mistakes the abstraction for reality itself. Human relationships aren’t securities with predictable correlations and quarterly reports. Their value is found precisely in the things that a portfolio model deems irrational: loyalty when the "stock" is down, investment without a guaranteed return, and commitments that defy any logical risk assessment. The real lesson isn't that we should run our lives like a hedge fund; it's that even the best models have their limits, and wisdom lies in knowing where the map ends and the territory begins.
