What I Learned About Investing from Darwin

Select one trait, inherit many free. A 60-year Soviet experiment breeding silver foxes for tameness alone accidentally produced floppy ears, curly tails, piebald coats, and puppy-like faces, because selecting one behavioral trait shifted the hormones governing dozens of others. Prasad wanted an investing equivalent: a single measurable filter that quietly signals overall quality.

Return on capital employed is that filter. ROCE is operating profit divided by capital employed (working capital plus fixed assets). Nalanda rejects management quality (unmeasurable, as Enron's polished executives proved), revenue growth (WeWork grew eightfold while burning cash), and margins (Costco's 3% margin beats Tiffany's 19% because Costco turns inventory in 31 days versus 521). A consistently high ROCE tends to bring competent management, durable moats, smart capital allocation, and the cash cushion to take risks, all for the price of one screen.

Robustness is the hidden survival engine. Life persists through 3.5 billion years of assault because it is robust at multiple layers: a DNA mutation often codes the same amino acid, a changed amino acid often folds the same protein, altered proteins often preserve the body plan. Two sea urchin species look identical yet develop completely differently. McKinsey transformed its geography, services, and hiring over a century while staying culturally the same firm.

Robust businesses evolve while staying themselves. Nalanda seeks firms that are robust on many fronts simultaneously:
1. High, durable ROCE
2. Zero or minimal debt
3. Fragmented customer and supplier bases
4. Strong competitive barriers
5. Stable management in a slow-changing industry

Crucially, robustness enables evolvability. Paints maker Havells survived a botched acquisition because its 52% ROCE gave it cash to fix mistakes. Robustness comes free with quality, just as evolvability comes free with biological resilience.

Separate proximate from ultimate causes. Biologists explain a bird's migration two ways: the proximate trigger (a cold snap on August 25) and the ultimate cause (millions of years of selection favoring migrants). Dung beetle horns can be explained by the hormones that grow them or the mating advantage that selected them. Both questions are valid but different.

Markets confuse the two constantly. A Fed rate hint, an OPEC breakdown, or a Greek default sends stocks tumbling worldwide, yet these are proximate noise divorced from long-term business success. When the Asian crisis hit in October 1997, Walmart and Boeing dropped, then rose 57% and 16% within six months. Three Indian banks under identical interest-rate regimes multiplied 16x, 33x, and 81x over two decades. The difference was management, not macro. Nalanda assigns exactly zero weight to macroeconomic forecasting.

Investing is a historical science, not a predictive one. Physics predicts; evolutionary biology explains what already happened. Darwin cracked natural selection, sexual selection, and common descent not with new data but by reinterpreting facts everyone could see: pigeon breeding, peacock tails, embryo similarities. Nalanda mimics this, analyzing only delivered historical financials over a decade or more, building zero projections.

Discounted cash flow is elaborate self-deception. DCF values a business as the sum of future cash flows discounted to today. But it requires forecasting a discount rate (built on the dubious volatility-equals-risk beta) and cash flows years out. A single percentage point change in discount rate swings present value 11-13%. Analysts could not predict Snapchat's numbers days ahead, yet DCF demands decade-long guesses. Nalanda values businesses on trailing earnings, buying at a median 14.9 PE versus the market's 19.7.

Convergence means success has a limited menu of forms. Unrelated species facing the same problem evolve the same solution independently. Caribbean lizards on four islands developed identical body types. Australian marsupials mirror placental wolves, mice, and anteaters. Sharks and dolphins share the same shape. There are only so many ways to swim fast or eat termites.

Business success converges too, so ask: where else has this worked? Nalanda invested in Naukri, India's leading job site, not because founders impressed them but because the model converged with two proven templates: old Yellow Pages directories (network-effect monopolies earning 40%+ margins) and seven global job boards from Australia to Japan showing identical economics. This mirrors Kahneman's outside view: before trusting your inside story, check base rates. The disciplined outside view on airlines (a cumulative $44 billion loss across US carriers from 2000 to 2013) says simply walk away.

Zahavi's handicap principle decodes corporate communication. In nature, a signal is honest only when it is costly to produce. A peacock's extravagant tail and a guppy's bright red coloration are reliable because they are dangerous handicaps only healthy animals can afford. Cheap signals get faked: small frogs lower their croak to fake size, milk snakes mimic venomous coral snakes.

Most corporate signals are cheap, therefore worthless. Press releases, glossy investor conferences, earnings guidance, and management interviews cost nothing to spin optimistically. Wirecard's CEO gave a flawless interview a year before his fraud arrest. Nalanda ignores all of these. It trusts only costly signals:
1. Decades of delivered operating and financial performance
2. Scuttlebutt from competitors, ex-employees, suppliers, and customers

A reputation built over decades cannot be faked cheaply. Scuttlebutt once revealed a company inflating sales through a subsidiary; its value later fell 98%.

Evolution runs fast short-term, slow long-term. Finnish scientist Bjorn Kurten found brown bear teeth changed at 13.8 units over 8,000 years but only 0.41 units over 400,000 years. The Grants watched Galapagos finch beaks swing dramatically year to year with droughts, yet stay range-bound across decades. Short-term fluctuation is not long-term direction.

Prasad calls this the Grant-Kurten Principle of Investing. For a high-quality business whose fundamental character stays stable, exploit the inevitable short-term price swings to buy, never to sell. L'Oreal endured lawsuits, recalls, price-fixing fines, and a 20% China sales drop between 2009 and 2020, yet remained the same global beauty compounder, its stock rising 450%. Nalanda invested $851 million (46% of fourteen years of deployment) during just 26 months of market panic, including $288 million in seventeen days of March 2020.

Punctuated equilibrium describes business too. Gould and Eldredge argued species stay static for eons, then change abruptly, rather than evolving gradually. Stasis is the default in nature. Prasad finds the same in commerce: excellent businesses remain excellent, weak ones remain weak, far longer than intuition suggests. Of the 1955 Fortune 500, a plausible 40-45% were still thriving sixty years later. Meanwhile perhaps 97-99% of firms that could have joined the list never did.

This justifies extreme laziness in both buying and selling. Because great businesses are rare and durable, the default is not to buy. Because they stay great, once owned, the default is never to sell. Nalanda never confuses a rising stock price with genuine business improvement, which keeps it out of hyped sectors like Indian infrastructure, where Reliance Power fell 95% from its IPO peak.

Compounding hides its power, then explodes. Twenty-four rabbits released in Australia in 1859 became ten billion by 1925, yet for decades almost nothing seemed to happen. Darwin grasped this: a 1% selective advantage spreads through a population in a few thousand generations. The counterintuitive lesson is that compounding produces nothing visible for a long time, which is precisely why impatient investors sell too soon.

A few extraordinary holdings carry the whole portfolio. Shelby Davis turned $50,000 into $370 million buying insurers and never selling, despite hundreds of dud picks. In Nalanda's first fund, seven of seventeen investments underperformed, yet Page Industries alone (up 82x over fourteen years) paid for all seven losers more than five times over. Prasad's costliest error was selling Shree Cement for a quick 2.2x gain; it later rose fivefold, a $400 million lesson in the tyranny of chasing internal rate of return over multiple.

Complexity yields to a repeatable algorithm. Honeybees make their most consequential decision, choosing a new home, through a stunningly simple process: scouts dance longer for better sites, and undecided bees randomly follow dancing sisters. This positive feedback loop reliably converges on the best available site without any leader. It does not succeed every time, but it has served bees brilliantly for thirty million years.

Nalanda's entire method is three repeatable steps:
1. Avoid big risks
2. Invest only in stellar businesses at a fair price
3. Own them forever

The failure of most investors, Prasad argues, is not choosing a wrong model but failing to repeat a good one consistently. Biologists spend lifetimes admitting how little they know about a single gene, while investors declare after a one-hour meeting that they have found the next great company. Humility about ignorance, encoded into a simple durable process, is the real edge.
