Intangible Assets and the Value Factor

The value factor’s traditional metric—low price-to-book ratio—has broken down because today’s high-return companies are loaded with intangible assets and intangible capital (brands, patents, networks, data, human capital) that accounting rules do not capitalize as assets, making balance sheets look cheaper than economic reality, and skewing the value factor toward industries where physical assets still dominate.

The Broken Assumption

The value factor rests on a simple premise: companies with low price-to-book ratios—that is, trading at a discount to the accounting value of their assets—are statistically cheap and likely to outperform. Over the past century, this worked. A company with $1 billion in assets on its balance sheet, trading at $500 million in market capitalization, was genuinely mispriced relative to the tangible value of factories, inventory, and equipment it owned.

But that logic depends on balance sheets accurately measuring economic value. For much of the 20th century, they did. A bank’s assets were mostly loans and Treasury securities. A factory owner’s assets were real property and machinery. A retailer’s assets were stores and inventory.

Today, the balance sheet is a historical artifact. A company like Apple has perhaps $400 billion in book value but commands a $3+ trillion valuation. That gap is not a mistake or a bubble. It reflects the reality that Apple’s value lies almost entirely in intangibles: brand strength, supply-chain relationships, patents, software ecosystems, data networks, and human talent. None of these appear as significant assets on the balance sheet. Apple spent decades on research and development; almost none of that R&D is capitalized as an asset—it was expensed immediately, per generally accepted accounting principles.

How Accounting Rules Hide Intangibles

Under accrual accounting, a company cannot recognize R&D as an asset. It must be expensed as it is incurred, regardless of whether the R&D produces a lasting competitive advantage worth billions. A pharmaceutical company spends $2 billion on drug research, and that $2 billion hits the income statement as an expense, reducing earnings and, therefore, reported book value.

By contrast, if a company buys another company for $1 billion and that purchase includes $600 million in “goodwill” (the premium paid over the target’s book value), that $600 million is recognized as an asset on the balance sheet, even though it represents the same underlying intangible value (brand, R&D, market position, human capital) that would have been expensed if developed internally.

This creates a massive valuation gap. A company that internally develops a valuable drug, brand, or technology has a lower reported book value than an acquirer of the same assets, because the acquirer gets to put goodwill on the balance sheet while the developer expensed it.

The Scale of the Distortion

Intangible assets now comprise roughly 60% of the market capitalization of the S&P 500, up from about 20% in the 1980s. That shift is not speculative; it reflects the genuine reorientation of the economy toward software, intellectual property, brands, networks, and data.

A few examples make the scale concrete:

• Microsoft: ~$200 billion book value, ~$3 trillion market value. The gap is almost entirely software, patents, and brand.
• Coca-Cola: ~$15 billion book value, ~$280 billion market value. The gap is brand value; the formula and recipe are world-class intangibles on neither balance sheet.
• Johnson & Johnson: ~$100 billion book value, ~$400 billion market value. The gap is patents, drug compounds, clinical trial data, and brand.

In each case, a traditional value investor using price-to-book would classify these as “expensive.” Yet they are not illiquid or unexamined; they are simply misrepresented by an accounting system designed for manufacturing and extractive industries, not knowledge work.

The Value Factor’s Divergence from Reality

As the economy shifted toward intangibles, the value factor increasingly tilted toward companies with large tangible asset bases: banks, mining, industrial manufacturing, utilities. These companies looked cheap by price-to-book because their balance sheets actually represented their economic value.

The software, biotech, consumer brand, and financial services companies increasingly looked expensive by the same metric, not because they were overpriced in absolute terms, but because their balance sheets radically understated their true asset value.

This distortion has contributed to the value factor’s notorious underperformance from 1990 to 2020. The value factor was not capturing cheap firms; it was capturing tangible-asset-heavy firms, which happened to be in low-growth, mature industries. The truly cheap intangible-heavy firms (or rather, firms cheap relative to their true asset value) were excluded from the value factor basket.

Attempted Fixes: Quality-Adjusted Value Metrics

Researchers and practitioners have proposed several alternatives to price-to-book to better capture value in an intangible-heavy economy:

Price-to-sales: Using revenue instead of book value is more robust to accounting distortions. A company with high R&D or brand investment still books sales; the P/S ratio is not distorted by expensed intangibles. However, P/S does not distinguish between profitable and unprofitable sales, and it can mislead.

Enterprise value to EBITDA: EBITDA (earnings before interest, taxes, depreciation, and amortization) tries to isolate cash generation from accounting artifacts. A company with high R&D expenses will have lower reported earnings, but EBITDA captures the operating cash generation regardless. This is more robust.

Profit-based metrics (ROE, ROIC): Instead of asking how cheap a company is, ask how profitable it is. The return on equity or return on invested capital of a firm with high-quality intangibles (strong brand, durable patents) will be high and stable. A quality factor tilted toward high-ROIC, low-price-to-earnings firms captures the true economic value, intangibles and all.

Adjusted book value (tangible book value): Some investors calculate book value minus intangible assets and goodwill, trying to isolate the tangible asset base. This works for capital-intensive firms but fails entirely for intangible-heavy firms (where tangible book value becomes negative or trivial).

Intangible capital measurement: A few academics (notably Baruch Lev and others) have proposed capitalizing R&D and brand investment, then calculating a balance sheet adjusted for capitalized intangibles. This requires estimating useful lives and amortization, but it produces a more economically realistic asset figure. Unfortunately, these calculations require custom analysis and are not standardized across firms or databases.

The Implication for Value Investors

The rise of intangibles has forced a reckoning. A strict price-to-book value factor no longer reliably identifies cheap firms in an economy where the cheapest firms are often those with intangible assets invisible to accounting.

Modern value investors have responded by:

1. Combining price-to-book with profitability screens (favoring cheap firms that also have high ROIC)
2. Using revenue multiples instead of book-value multiples
3. Explicitly excluding or underweighting intangible-heavy sectors (technology, biotech) and then supplementing with quality factors
4. Developing custom indices that attempt to adjust book value for estimated intangible capital

The net result is that “the value factor” is no longer a single, well-defined metric. Different value indices now diverge significantly from one another depending on their approach to intangibles and quality.

Has the Value Premium Died?

A persistent question in finance is whether the value factor is broken. The answer is nuanced. Traditional price-to-book value has dramatically underperformed. But value defined as “cheap relative to true economic profits and intangible quality” has not disappeared; it has just become harder to measure and implement.

A portfolio of cheaply valued companies with high profit margins, durable competitive advantages (moats), and reasonable intangible quality has continued to outperform growth over long periods. But this portfolio looks very different from a simple price-to-book screen.
