Learn the fundamentals behind this asset.
Market cap is shares times price. A simple formula that produces wildly unequal numbers: a single US tech name can be worth more than every company on a LATAM exchange combined.
A venue where buyers and sellers meet at a price. Six exchanges cover almost everything a LATAM retail investor will ever touch, and the differences between them are mostly about access, currency, and tax.
Cross-border equity wrappers: how Brazilian retail accesses Apple, and how the US accesses Itaú. Two depository-receipt structures, six dimensions of difference, and a path picker that maps real combinations of investor and target stock.
A stock is a fraction of ownership in a real company. Buy one share and you own a piece (usually a tiny piece) of every desk, factory, contract and brand the company runs. The price moves because the market keeps revising what that whole pie is worth.
