To clarify for new traders: you might be thinking, if stock prices go up and up and up that's great right?? Well no. Let me explain : Let's say you have 1 Facebook (FB) stock and it is worth $20. Also, a bread at you local grocer is $20.
In two years, your one stock is now worth $40. In other words, you have made 100% profit since your stock was bought at $20. HOWEVER, you go to your local grocer and find that the price of a bread is now $35.
Do you see the problem? Value can be illusive. This is the illusion of profit when hyperinflation is happening.
