Some finance-related things people say that irrationally annoy me
People use "ETF" as a synonym for "stock ETF". Someone asks where to invest 50k and gets a reply that they should just put it into an ETF. But which ETF? Bonds, gold, oil, real estate, Bitcoin, something else? It's like when someone asks for summer vacation tips and you tell them they should travel by plane.
Some people don't understand the very simple concept of net worth. They say that their net worth is $1M and later it turns out that it's just their portfolio, home equity is not included.
Some people think that the US stock market has historically outperformed the European stock market, therefore it's a better investment. I mean, do they think other investors can't see this very obvious fact? Why assume that this is not priced in?
Some people expect a 10% annualized total return of S&P 500 based on extrapolating history. But reality is more complicated. The fact that the US has exceeded expectations in the past doesn't mean it will do so in the future. The 10% return mixes real return and inflation.
