1 year forward growth - Average major brokerage firm financial analyst 
estimate of future year's growth in earnings.
12 month yield - Change in price of fund plus dividends 
received per share over past year divided by price of fund. A better measure of 
total return than simply rate of price rise.

may withdraw each year to pay for marketing and other non-operating expenses. 
Generally absent among ETFs but common and often large in actively traded funds.
3 year earnings growth - Annualized rate of increase of 
earnings of past three years.
YTD - The calendar Year-To-Date return from January 1 to the

Annual turnover - Percentage of value of stocks in a portfolio 
that are sold and replaced with new stocks each year. Turnover in indexing 
should be low.
Naked options trading is very risky - many people lose money trading them. It is recommended contacting your broker or investment professional to find out about trading risk and margin requirements before getting involved into trading uncovered options.
