Alternative investments are typically not directly connected to stock markets.
This is really important for your pension or investment money; if you have money invested in a product or structure that can be affected by war, terrorism, famine, political instability or international trade disputes, then you could lose some or all of your money during the investment term.
A good example would be money invested in a fund with a financial institution or insurance company, which can rise or fall in value, typically because it is correlated or directly connected to the performance of the stock market.
The stock market in turn is regularly affected by political matters or matters that logically should not affect the value of an investment. A simple negative comment or social media post about a particular financial economic position, is often enough to send markets spiraling into negative values.
