The counterintuitive finding buried in a paper that was not written to make it is this: the same management quality that earns a company its premium val...
Good management and good stock returns are not the same thing. On the evidence in Fillat and Garetto's NBER working paper, they may even pull in opposite directions once a company grows large enough to go shopping.
That is not the conclusion the authors set out to reach. Their subject was the link between management quality and multinational expansion, and their headline claim is straightforward: better-run firms expand abroad, and they carry a valuation premium even while they are still small and domestic. But the number that matters for an investor is not the multiple a firm commands. It is the return an investor earns from owning it. Those two things diverge, and the direction of the divergence is the part worth pricing.
Why a Premium Is a Warning, Not a Reward
The word "premium" does a lot of quiet work in this paper, and it is easy to misread. When the authors say multinational enterprises carry a larger risk premium than purely domestic firms, they do not mean these companies are riskier to own. They mean the opposite. Multinationals trade at higher multiples because the market has already recognised their quality: better management, more diversified revenue, higher profitability. The premium is the market's applause, paid in advance.
The problem with applause paid in advance is that it is deducted from future returns. A higher entry multiple, all else equal, is a lower forward return. So the very features that make a multinational look safer, the diversified revenue stream and the stronger management bench, are the features that have already been capitalised into the price. Domestically oriented firms, run on average by weaker teams and exposed to a single economy, look riskier, and the paper's factor-adjusted returns confirm that the market compensates that risk with higher realised returns over the cycle.
This is the first rung of the evidence ladder, and it inverts the intuitive story. The instinct that domestic firms should be the risky, low-return laggards, while global champions should be the safe compounders, gets the return direction exactly backwards.
The Acquisition Channel Is Where Value Leaks
The more actionable finding sits one layer down. Within both the domestic and multinational groups, companies that make acquisitions underperform companies that do not. The paper's factor-adjusted return data separates firms not just by geography but by acquisition strategy, and the ranking is consistent: domestic non-acquirers and multinational non-acquirers earn higher returns than their deal-making peers. The share-price reaction to individual acquisition announcements confirms the same thing at the transaction level, for domestic and cross-border deals alike.
The mechanism connecting management quality to this value leak is almost mundane. Better managers run more profitable firms. More profitable firms generate more cash. More cash, combined with the confidence that comes from a track record, funds acquisitions. And acquisitions, on average, transfer value from the buyer's shareholders to the seller's. The premium paid in a deal is real money leaving the acquirer's balance sheet; the synergies used to justify it are a forecast. The paper's average tells you which side of that trade wins.
None of this says that no acquisition ever creates value. Some do, and the distribution has a right tail worth respecting. But an investor allocating on averages, rather than on a specific deal thesis they can underwrite themselves, should treat a serial-acquisition strategy as a red flag rather than a growth story. The narrative a management team offers when it announces a roll-up of competitors is precisely the narrative the average outcome contradicts.
Where the Counterargument Bites
The cleanest challenge to this reading is survivorship and selection. Firms that make many acquisitions may underperform not because acquisitions destroy value but because struggling firms buy their way toward growth they cannot generate organically. If weak organic prospects cause both the acquisition spree and the poor returns, then the acquisition is a symptom, not the disease, and blaming the deal is a category error.
The paper's transaction-level evidence blunts this objection without fully retiring it. The negative average share-price reaction at the moment of announcement is a clean event study: the market marks the buyer down on the news itself, before any operational underperformance has time to show up. That timing points to the deal, not the pre-existing condition. Still, an honest reading concedes that the two stories are entangled in the cross-section, and the paper's averages cannot fully separate a bad deal from a bad business making a deal.
There is a second tension the paper does not resolve. If multinationals are genuinely better-managed and more profitable, the case for owning them does not vanish; it just relocates. Lower expected return on a higher-quality, lower-volatility asset can still be the right holding for an investor who cares about drawdowns rather than raw return. The finding is not "avoid multinationals." It is narrower and more useful: do not expect a quality premium and a return premium from the same holding, because the market has already chosen which one to pay you.
What This Says About the UK Market
The geography of who buys whom turns this from a portfolio observation into a market-structure one. The paper identifies UK businesses as the prime targets for US companies expanding abroad. Read alongside the value-destruction finding, that is a double-edged fact for anyone invested in UK equities.
On one side, it is cold comfort for the shrinking London market. The steady disappearance of listed UK companies is not only a story of weak domestic growth and cheap valuations; it is also a story of British firms being the most acquired feedstock for American expansion. Every takeout removes a name from the index, and the index does not replace them at the same rate.
On the other side, the paper's core finding offers a genuinely contrarian consolation to holders of unloved UK domestics. These are the purely domestic, single-economy, often unglamorously managed firms that the factor-adjusted data says earn the highest returns over the cycle, precisely because they look riskier and carry no quality premium in their price. UK domestic equities have lagged badly while the US and other markets ran ahead. The paper's framework suggests that underperformance is at least partly the setup for the compensation, not a permanent verdict on the assets. This link is the weakest in the chain and I flag it as such: applying a US-sample study to the specific case of UK domestics is an inference the paper does not directly test.
The Condition That Would Change the View
The thesis rests on averages, and averages can be dominated by base rates that shift. The read holds as long as acquisition premiums stay rich and synergy realisation stays disappointing, which is the historical norm. It would weaken if a structural change, cheaper financing that lowers the premium paid, or acquirers with genuinely repeatable integration edges, moved the average deal from value-destroying to value-neutral.
Until that shows up in the announcement-day reactions, the cleaner reading stands. Judge a company by the returns it produces for owners, not by the multiple the market awards its quality, and treat a management team's enthusiasm for buying its competitors as a cost to be underwritten rather than a virtue to be applauded. The best-run firm in a sector and the best stock in that sector are frequently not the same company, and the acquisition strategy is often what separates them.
