Step 1 -- Clarify your access path before you debate tickers
SIC listings, local fund platforms, BDR-style wrappers, and global brokers each change available tickers, custody, and tax reporting.
Write down which share class or listing you are buying and how dividends and gains are treated where you live -- that layer sits on top of any “SPY vs QQQ” debate.
Step 2 -- Run the same economic checklist as any global investor
Index methodology, TER, liquidity, concentration, currency of exposure, and replication structure still matter regardless of passport.
Cognitor analyzes the underlying U.S.-listed sleeve; you translate all-in cost after local fees, FX, and tax.
Step 3 -- Stress the sleeve with six independent lenses
HELIOS, NEXUS, ARGOS, VEGA, ATHENA, and PSYCHE read the same evidence pack through different domain boundaries before five SENIOR verdicts and PRIME synthesis.
Use that map to see where the scenario is contested -- not to outsource position sizing to a headline.
Step 4 -- Keep two columns of invalidations
Column A: what economic evidence would flip your thesis (rates, earnings, flows, geopolitics).
Column B: what operational constraint would flip the channel (FX spike, liquidity window, rule change, wrapper fee shock).
Many LATAM mistakes are correct on the ETF story but wrong on the execution stack -- track both explicitly.
Step 5 -- Pick the country hub that matches your tax residence
Cognitor publishes localized hubs so operational and tax documentation matches jurisdiction -- not a one-size English page with a different flag.
Scenario research on the 40-ticker universe is shared; how you execute it is not.
