Understanding market forces

In my experience, to truly succeed as an investor, it’s essential to understand the driving forces behind market behavior. Market movements aren’t random—they’re influenced by a range of economic theories and dynamics. The following books provide valuable insights into these forces, offering a deeper understanding of how global financial markets operate and what shapes their trends.

Nassim Nicholas Taleb – "The Black Swan"
- Summary:
  
  Taleb explores the concept of rare, unpredictable events—so-called "Black Swans"—that can have massive impacts on markets and society. These events are often overlooked by traditional risk management models, leading to devastating consequences when they occur. Taleb illustrates how these unpredictable shocks shape our world, often more than gradual, expected changes.
- Why read it:
  
  This book challenges conventional thinking about risk and uncertainty, showing that many major historical and financial events were "Black Swans." It's a vital read for investors who want to build resilience in the face of market volatility.

The book also explains the consequences of under-consumption and the role of interest rates in managing economic stability.
- Why read it:
