Range of annualized real returns of US equities for different holding periods (1850–2008)
Since 1850, a US investor who bought a broad basket of equities could have earned a real return of anything between –62% and 172% in one year (assuming no taxes). If she had held the stocks for 25 years, the range of possible annualized returns would have been smaller but positive (between 1% and 12% per annum). Had she invested in government bonds, the range of returns would have been narrower, but because of inflation she could still have suffered a negative real return after 25 years.
