What Is a Stock, Really?
When Maya buys one share of Apple, she owns a literal sliver of the company, not just a number on a screen.
A share of stock is a literal slice of ownership in a company, not a lottery ticket, not a number that moves around for fun. When Maya buys one share of Apple, she owns a tiny fraction of every iPhone sold, every dollar of profit, every building the company owns, roughly one fifteen-billionth of it, since Apple has issued somewhere around 15 billion shares.
That ownership comes with real rights: a claim on future profits, and a vote on major company decisions, even if her one share barely moves the needle. It also comes with real risk: if Apple performs badly, her shares are worth less, and nobody guarantees her money back.
This is the whole reason stocks have historically outgrown cash and bonds: owners get paid for taking on a business's risk, not for lending it money at a fixed rate. Maya's 70% allocation to stocks is a bet on ownership over lending.
