GDP, or Gross Domestic Product, is the total value of all goods and services produced within a country’s borders during a specific time period, usually a year or a quarter.

Market cap is the market price of an entire company.

Price-to-earnings (P/E) ratio compares a company’s current share price to its per-share earnings. It may also be known as the “price multiple” or “earnings multiple”, and gives a general indication of how expensive or cheap a stock is.

The equity risk premium (ERP) is the extra return that investors expect to earn from investing in the stock market compared to investing in a risk-free asset.

Earnings yield is a financial ratio that expresses a company’s earnings per share (EPS) as a percentage of its stock price.

Risk-Free Rate represents the theoretical return an investor could potentially earn on assets that are considered virtually free of default risk, typically referring to U.S government-issued bonds.

The S&P 500 Index is a float-adjusted, capitalization-weighted index of 500 U.S. large-capitalization stocks representing all major industries. It is a widely recognized index of broad, U.S. equity market performance. Returns reflect the reinvestment of dividends. This index is unmanaged and investors cannot invest directly in this index.

The MSCI World Index (Net) is a free float-adjusted, market capitalization-weighted index that is designed to measure the global equity market performance of developed markets. The index covers approximately 85% of the free float-adjusted market capitalization in each country. This benchmark calculates reinvested dividends net of withholding taxes. This index is unmanaged and investors cannot invest directly in this index.

The Fund’s portfolio tends to be invested in a relatively small number of stocks. As a result, the appreciation or depreciation of any one security held by the Fund will have a greater impact on the Fund’s net asset value than it would if the Fund invested in a larger number of securities. Although that strategy has the potential to generate attractive returns over time, it also increases the Fund’s volatility.

Investing in foreign securities presents risks that in some ways may be greater than U.S. investments. Those risks include: currency fluctuation; different regulation, accounting standards, trading practices and levels of available information; generally higher transaction costs; and political risks.

Investing in value stocks presents the risk that value stocks may fall out of favor with investors and underperform growth stocks during given periods.
