Based on many questions and statements, it is quite evident that too many people don't have a basic understanding of the Stock market. They don't know the difference between an ETF, CEF and Closed End Mutual Fund, shorting a stock, Puts, Calls and much more. The statements about Oil Futures is laughable. The same futures selling apply to pork bellies, wheat, sugar, cotton, soy beans and every other commodity. Unless, they take the time to educate themselves about the Stock Market, they will continue to make laughable statements and ask ridiculous questions.
