# When to buy

The most realistic distinction between investors and speculators lies in their attitudes towards stock market changes. The primary interest of speculators is to predict market fluctuations and profit from them; the primary interest of investors is to purchase and hold suitable securities at appropriate prices. In fact, market fluctuations are important to investors because when the market is at a low price, investors will rationally make buying decisions; when the market is at a high price, investors will inevitably stop buying and may even make selling decisions.
