Bolsas y Mercados Argentinos SA (BYMA.BA) : juste valeur

Thèse ACCE

Bolsas y Mercados Argentinos (BYMA) runs the Buenos Aires stock exchange and its clearing and settlement infrastructure, earning fees on trading volume, listings and post-trade services across equities, fixed income and derivatives. The moat is the exchange itself: a single national venue with entrenched participants and high switching costs, which is why operating margins sit at 57.7% on a gross margin of 74.7%. Revenue grew 25.3% in the latest period, and trailing ROE of 27.5% shows that growth is not being bought with capital. The stock trades at 9.7 times trailing earnings and 4.6 times forward, a gap that implies the market expects earnings to fall or that Argentine macro and currency risk is being priced heavily. The name is worth a deeper look if you can form a view on whether peso volatility and capital controls will keep trading volumes high enough to sustain that margin structure, since that single question explains most of the spread between the trailing and forward multiples.
