Speculation on the financial markets is an extremely difficult task. We often have to admit to ourselves that we have made a mistake or consciously participate in a speculative bubble, knowing that many people will lose their life savings. During the lecture, investors will see many situations in which unconventional thinking brought substantial profits, while classical investment rules required a completely different strategy. The contemporary investor must adapt to the ever-changing market conditions and … changes that have occurred in our daily lives. I hope that this lecture will turn your thinking upside down and inspire you to look at the financial markets from a broader perspective.
