Level 3: Saving & Growing · 7 мин
Investing Vocabulary, Without the Mystery
Stocks, bonds, funds, and the handful of words that unlock every article.
Stocks are ownership slivers of companies; bonds are loans to governments or companies; funds are baskets holding many of either. An INDEX fund is a basket that simply copies a market list at very low cost. It is the workhorse concept of modern saving-for-later.
Risk and return travel together, always. Higher possible growth means bigger possible drops; anyone offering high return with no risk is describing something that doesn't exist (the SEC's investor.gov keeps a museum of what those pitches actually were).
Two numbers explain most outcomes: TIME (years invested: the compounding lesson again) and COST (expense ratios: a 1% annual fee versus 0.05% consumes a startling slice of a lifetime's growth). This lesson is orientation, not advice: our whole site teaches, and never tells you what to buy.
