Uh, how 'bout a translation for those of us who don't speak "acronym-ism".
Those aren’t acronyms, they are ticker symbols. Go to Yahoo Finance, plug them into “Get Quotes”, then click on “Profile”, and you will find an explanation of what type of investment it is. Charts of the history of the trading price are also there.
Those are the trading symbols for several Exchange Traded Funds (ETFs).
