A Morgan Stanley study of 183 Latin American companies found that firms in the top quartile for governance practices outperformed those in the bottom quartile by 224% cumulatively since 2010 on market-capitalisation-weighted indices. On an equal-weighted basis, the gap was 145%. That’s the market’s polite way of saying the people with the best protection for capital got the best results, while everyone else got the leftovers.
The Rio Times says the study was reported by InfoMoney and that the underlying Morgan Stanley note is not public. It also says the headline number is real and does not mean what the headline says. That matters, because financial reporting loves a clean number almost as much as it loves hiding the machinery behind it.
Who Gets Protected
The article says concentrated ownership is the regional norm in Latin America, with controlling families and state shareholders common across Brazilian, Mexican, Chilean and Colombian listed companies. That makes minority-shareholder protection the live governance question, not some abstract sermon about board independence. In other words, the fight is over who gets to call the shots and who has to live with the consequences.
The comparison in the study is between the top quartile and the bottom quartile of the sample, not between good governance and an average peer. The 224% figure is cumulative over roughly fifteen years, from 2010 to the present, and the equal-weighted figure strips out some of the large-company effect. The spread is real, but so is the framing. A headline can make a hierarchy look like a universal law.
What the Market Calls “Governance”
Brazil built a market segment around this. B3’s Novo Mercado listing tier, created in 2000, requires a single class of voting shares and a minimum free float, and exists because investors would not otherwise price Brazilian equity on comparable terms. That’s not a moral victory. It’s a workaround for a system where ownership concentration is so entrenched that even capital needs special rules to feel safe.
The article says the events of the past twelve months are the argument in practice, citing a collapsed bank, a state-controlled bank reporting fraudulent documentation and public pension funds buying uncovered credit notes as governance failures before they are credit events. The damage lands below, where workers, savers and pension holders absorb the blast after the people at the top have already moved on.
The Limits of the Numbers
A fifteen-year backward-looking spread does not establish that governance causes returns. The article says well-governed companies also tend to be larger, more liquid, more widely covered by analysts and more likely to be held by foreign institutions, and each of those is independently associated with performance. Finance likes to dress correlation up as commandment, then act surprised when the story gets messy.
The honest claim, the piece says, is narrower and still useful: in Latin America, the governance ranking has separated outcomes to a degree that would be hard to dismiss as noise across 183 companies and fifteen years. For a portfolio manager, the operational use is as a screen rather than a strategy, because governance rankings are slow-moving and publicly available, which means any premium they carry is knowable in advance and therefore at least partly priced.
That leaves the real function of the screen. The article says the residual value lies in avoidance rather than selection. A screen that keeps a portfolio out of the bottom quartile captures most of the measured gap without requiring a view on which well-governed company will outperform. The system doesn’t reward justice. It rewards not getting burned.
The sourcing note says no report title, publication date or named strategists appear in the coverage, and the Morgan Stanley note itself is not public. The Rio Times reports it as InfoMoney’s account of a Morgan Stanley study, carries both the 224% and 145% figures, and does not present either as an independently verified result. Even here, the gatekeepers keep the file closed while everyone else is asked to trust the numbers.
