Loads of people play the stock market, but few understand the inner workings of even the most common securities. A favourite tool is the ETF - but where do they come from, and how do they really work? Is it possible to build one yourself?...
Looking around, I couldn't find an ETF covering the sector I'm interested in. There are a lot of them out there - representing anything from the global lithium battery industry (LIT) to the casino gaming world (BJK) - but not the one I was hoping for.
