What I Learned About Investing From Darwin
by Pulak Prasad
“Pulak Prasad’s fresh take on Darwin’s principles illuminates the complexities of markets with uncanny clarity.”
At first glance, Charles Darwin’s theory of evolution might seem worlds apart from the daily tumult of the stock market. Yet, as Pulak Prasad contends in What I Learned About Investing from Darwin, the very same principles that shape the natural world can also guide successful investing. Adaptation, survival, competition—these are terms we typically associate with biology. But if you look closely, they resonate just as strongly with the realities of capital allocation.
From time to time, markets shift so drastically—think of the 2008 financial crisis or the dot-com bubble—that they feel like cataclysmic events in nature, wiping out weaker species and leaving only the fittest to flourish. Prasad sees parallels everywhere: from how companies evolve (or fail to) under shifting consumer demands, to how certain investing strategies survive in a climate of fierce competition. This blog post will explore the major themes of What I Learned About Investing from Darwin, offering both an overview of its core lessons and a taste of the author’s distinctive approach.
Who is Pulak Prasad?
Pulak Prasad is an investor with decades of experience in global markets. Having worked in private equity and founded Nalanda Capital—an investment firm focused on Indian equities—Prasad has a reputation for patience, discipline, and thorough research. But unlike many in finance, he isn’t content simply to crunch numbers and look at quarterly reports. Instead, Prasad draws inspiration from diverse fields, biology being one of his favorites.
It’s not just lip service. Reading What I Learned About Investing from Darwin feels like attending a conversation between a seasoned investor and a fascinated naturalist. The premise? Markets, like ecosystems, are in constant flux. Companies, like species, fight to survive, adapt to new conditions, and sometimes fail. Shareholders, like apex predators, can exert tremendous influence—though their success depends on reading the environment correctly. Through telling personal anecdotes and historical examples, Prasad weaves these threads into a cohesive argument for an “evolutionary mindset” in investing.
Main Themes
1. Variation: The Fuel for Opportunity
In Darwin’s theory, variation among species members is the foundation of natural selection—without differences in traits, there’s no mechanism for evolution. Prasad applies this idea to the stock market in an intriguing way. He reminds us that every listed company has its own story, its own “variation,” and that these differences are precisely what create investment opportunities.
Rather than seeing the market as a uniform playing field, Prasad urges investors to celebrate its diversity: from niche tech firms pioneering new software, to centuries-old manufacturing powerhouses adapting to the digital age. Identifying which “variations” are advantageous becomes a crucial skill. Just as an organism’s unique attributes might help it endure drought or avoid predators, a company’s strategic innovations, strong competitive moats, or shrewd leadership can help it thrive amid market shifts.
Takeaway: Don’t shy away from companies that look different. Variation can sometimes signal a hidden advantage—just be sure to assess whether that advantage is truly viable in the long term.
2. Selection: The Harsh Reality of Market Competition
Darwin posited natural selection as the mechanism that decides which traits (and thus which organisms) survive to pass on their genes. In investing, selection occurs when markets “vote” on a company’s fate over time. If a firm’s strategy succeeds, demand for its stock generally rises; if it fails or stagnates, it gets punished by falling share prices or waning investor interest.
Prasad contends that selection in markets is relentless. It doesn’t matter how storied a brand is or how large a company has grown; if its fundamental business model no longer resonates with consumers, the market will eventually reflect that. This reality can be sobering, but it’s also a reminder not to rest on the laurels of past glories.
For investors, selection underscores the importance of staying informed and periodically re-evaluating holdings. Even the strongest businesses can lose their competitive edge. Like a biologist monitoring how certain traits persist or vanish in a species, investors should track the key performance indicators that signal a company’s ongoing vitality.
Takeaway: Market selection punishes complacency. An “evolutionary” investor stays curious, re-checking each holding’s competitive edge periodically—just as nature constantly retests an organism’s fitness.
3. Adaptation: Thriving in a Changing Environment
Perhaps the most famous Darwinian principle is adaptation. Species that successfully adapt to new environments tend to flourish, while those that cling rigidly to outdated traits risk extinction. Prasad illustrates how companies follow a similar pattern. Think of how Blockbuster failed to adapt to streaming, while Netflix transformed itself multiple times to keep pace with technology and consumer preferences.
But adaptation isn’t just for companies. Prasad insists that investors, too, must adapt—both to external market conditions and to their own evolving perspectives. He shares examples of times he clung to an investment thesis for too long, only to lose money when the thesis no longer reflected reality. Ultimately, investing is not a static discipline. Strategies must evolve as the global economy, cultural trends, and geopolitical landscapes shift.
Takeaway: Check your biases regularly and be willing to pivot. Adaptability—both for companies and investors—can mean the difference between long-term success and quiet obsolescence.
4. The Power of Patience and Long-Term Thinking
Darwin’s work didn’t just teach us about survival of the fittest; it also taught us that evolution unfolds over extensive time horizons. Prasad draws on this to champion long-term thinking in investing. Just as a species can’t evolve beneficial traits overnight, a company’s real value can’t always be recognized in a single quarter or even a single year.
In Prasad’s view, many investors get swept up in short-term noise: sensational headlines, daily market swings, and hype cycles. The Darwinian lens reminds us that genuine adaptation, sustainable competitive advantage, and business transformations typically take time. Patience, therefore, becomes a strategic advantage. By allowing good companies the breathing room to execute on ambitious plans, investors can reap the benefits of compounding growth.
Takeaway: Darwin’s timeline wasn’t measured in days or months—it was measured in millennia. While you don’t have to wait eons for a payoff, adopting a multi-year horizon can help you avoid impulse decisions and harness the power of compounding.
5. Ecological Balance: Knowing Your Niche
Prasad also draws parallels to the concept of “ecological niches.” In nature, each species occupies a niche—a set of conditions under which it can best survive. The market is similarly an ecosystem. Different investment styles (value, growth, momentum) or sectors (tech, healthcare, consumer staples) represent distinct niches. Some thrive during boom times; others remain stable during downturns.
In What I Learned About Investing from Darwin, Prasad encourages readers to figure out their own “niche” as an investor. Are you more suited to patient, research-intensive stock picking, or do you prefer systematic trading strategies? Do you have an edge in spotting undervalued small caps, or do you excel at identifying high-growth tech disruptors? By acknowledging your own strengths—and the environment you’re best suited to—you can focus your energy where it’s most likely to yield results.
Takeaway: Don’t try to be all things to all people. An investor, like a species, is more resilient and effective when they specialize in a niche that matches their unique skills and risk tolerance.
Practical Applications
Investment Checklists
Prasad suggests creating checklists modeled on Darwin’s meticulous observation methods. Before committing to a stock, examine key factors: industry growth, leadership adaptability, financial robustness, and any sign of “favorable variations” that might indicate a lasting moat.Periodic “Fitness” Tests for Your Portfolio
Just as natural selection demands constant reevaluation of traits, so too should investors regularly assess each holding’s fundamentals. Has your company kept up with technological change? Are its revenue streams healthy and diversified? An honest, data-driven “fitness test” can prevent stubbornly holding onto outdated ideas.Mental Models from Biology
Concepts like “coevolution,” “symbiosis,” and “ecosystem dynamics” can spark new insights. For instance, coevolution might inform how you view the relationship between two companies—like a software provider and its network of partners—as they evolve in tandem.Long-Term Scorecard
Prasad recommends focusing on multi-year performance rather than daily or monthly fluctuations. By maintaining a scorecard that records annual or even 5-year benchmarks, you keep your eyes on the Darwinian arc—slower but more meaningful growth patterns—rather than short-term blips.Explore Adjacent “Habitats”
The author highlights how some of the best investment ideas come from looking at adjacent fields. Just as species often migrate to similar but slightly different habitats, you might find potential multi-baggers by examining markets with similar structures or consumer behaviors to those you already know.
Why This Book Matters
The global financial landscape can appear chaotic, much like the natural world. But Prasad’s analogy offers a reassuring framework: it’s not pure randomness but an evolutionary playground where only the most adaptable and resilient strategies prosper. For readers who find standard finance texts dull, What I Learned About Investing from Darwin offers a refreshing viewpoint. You’ll learn to see a stock chart not just as a line graph but as the living story of a “species” fighting for survival in an unforgiving environment.
At the same time, the book doesn’t skimp on tangible investing know-how. Prasad’s ideas about checklists, thorough research, and contrarian thinking align well with the discipline championed by legendary investors like Warren Buffett or Charlie Munger. What sets Prasad apart is his knack for weaving these principles into a broader narrative about life, change, and survival—a narrative that resonates across disciplines and centuries.
Final Thoughts
In an era of meme stocks, frenetic trading, and fleeting market fads, What I Learned About Investing from Darwin reminds us that true success takes time and requires adaptation. Pulak Prasad’s central message: Treat investing as an ecosystem, with each company, competitor, and investor playing a role in an ever-shifting environment. By learning from nature’s laws—variation, selection, adaptation, niche specialization—we gain a deeper perspective on market forces and sharpen our decision-making.
So, if you’re looking for new frameworks to make sense of your portfolio—or simply want a more meaningful lens through which to view finance—this book is a worthwhile addition to your reading list. Darwin may never have dabbled in the stock market, but Pulak Prasad makes a compelling case that his evolutionary wisdom can guide us through its twists and turns. By adopting a Darwinian mindset, investors might just discover the power to outlast volatility, survive inevitable challenges, and ultimately thrive in the unpredictable but endlessly fascinating jungle of global finance.
