Investors Expect More Than Double Realistic Long-Term Returns
Most investors dramatically overestimate long-term gains. Here's what the historical data actually shows about real annualized returns.
American investors are setting themselves up for disappointment, expecting long-term portfolio returns that history shows are more than double what markets realistically deliver, according to a MarketWatch analysis that cuts through widespread optimism with hard data.
