What it means
A stock exchange is a regulated market where companies raise money by selling shares and investors trade them. The BMV lists large Mexican companies in sectors such as retail, telecommunications, food and beverages, mining and finance.
Trading is done in Mexican pesos. The main yardstick of the market is the S&P/BMV IPC, an index that tracks the performance of the most traded companies.
An index is a basket of shares used to summarise how a market is doing. Many funds and derivatives are linked to it, so it serves as the benchmark for Mexican equities.
There is also a second exchange, called BIVA, which opened in 2018 to add competition. Both trade shares, though the BMV remains the larger and better known.
Settlement and custody services are provided by separate institutions behind the scenes. For foreign investors, there are two sources of return: the change in share price and the change in the peso against their home currency.
A share can rise in pesos and still produce a poor result in dollars if the peso weakens. Many foreign investors therefore use funds that hold Mexican shares, or hedge the currency to remove that effect.
The exchange matters to businesses beyond investing. Companies trading with Mexican partners watch it as a gauge of economic confidence, and firms planning to raise money in Mexico consider listing there.
It also illustrates how emerging market exchanges tend to be more volatile than those of larger economies. Another point for managers is that listing rules shape corporate behaviour.
Companies on the exchange must publish audited results, tell the market about important events promptly, and meet governance standards. Those obligations cost money, but they also give lenders and customers more confidence in the business.
In practice
Real-world examples.
Example
A Mexican bottler wants to expand its plants and sells new shares on the exchange. The proceeds fund new equipment, and the company gains a public share price that employees can use for share-based bonuses. Its finance team now publishes quarterly results to meet listing rules.
Example
A US pension fund adds Mexican shares to its emerging markets allocation and buys through an exchange-traded fund. The fund manager tracks the S&P/BMV IPC to judge performance. She also monitors the peso because it affects returns in dollars.
Example
A Canadian mining company with operations in Mexico considers a secondary listing on the BMV. A local listing would make it easier for Mexican investors to hold the shares and could reduce its borrowing costs in the region. The board weighs these gains against the added reporting costs.
Formula
Calculation
Dollar value of investment = (Shares x Price in pesos) / Pesos per dollar
Suppose a US investor buys 1,000 shares at 100 pesos each when the rate is 20 pesos per dollar (an assumed rate for illustration). The cost is 1,000 x 100 = 100,000 pesos, which is 100,000 / 20 = $5,000. Later the shares rise 10% to 110 pesos, but the peso weakens to 22 pesos per dollar. The shares are now worth 1,000 x 110 = 110,000 pesos, which is 110,000 / 22 = $5,000. Despite a 10% gain in pesos, the dollar return is zero because the currency move cancelled it out. The example is simplified and ignores dividends, fees and taxes, but it shows why both numbers must be tracked.Case study
Seen in the real world.
Sol del Valle Foods is an illustrative, fictional Mexican company that processes fruit for export. It has grown from a family business to annual revenue of $200,000,000 and needs $50,000,000 for new factories. Its owners consider borrowing but prefer not to carry more debt.
They decide to list on the Mexican Stock Exchange and sell 20% of the company to the public. Listing requires audited accounts, an independent board committee and regular disclosures, which raise running costs by about $1,000,000 a year. In return, the company raises the money it needs and gains a share price that shows its worth.
In this illustrative story, the first year is mixed. The share price rises 15% in pesos, but the peso weakens, so foreign holders earn less in dollars. The management team learns to explain currency effects clearly in its investor presentations.
Watch out
Common mistakes.
- Judging foreign investment returns using only share price moves and ignoring the peso exchange rate.
- Assuming the BMV is the only exchange in Mexico, when a second exchange called BIVA also operates.
- Treating the index as a guaranteed measure of the whole economy, when it tracks only the largest listed companies.
