The only time past performance really means anything in investing is when it's to illustrate how well an individual investor or fund manager has done - mainly how much money they've piled up and managed to hold on to.
Past performance of companies and individual investments (stocks, bonds, commodities, options, etc.) doesn't mean much, unless it's in reference to an individual investor or money manager's ability to invest for themselves using such investments as tools - i.e., a track record of success or failure of such an investor.
If someone is going to give me advice or criticism of my own investing, or try to sell me on their methods, or get me to put a little money to work with them, they'd better have a verifiable track record of success going back many years or decades.
