In a recent book, finance professor Vesa Puttonen recounts how he began investing during his military service, using half of his army daily allowances to invest in a company named Mancon. At the time, Puttonen was unfamiliar with the concept of diversifying investments and was overly confident in his financial decisions. Unfortunately, this lack of knowledge led to dire consequences when Mancon went bankrupt in 1989, resulting in the loss of nearly all his savings, including funds from his summer job and his first-year student loan.

The bankruptcy experience was pivotal for Puttonen, igniting a passion for understanding financial theory and the importance of prudent investment strategies. He emphasizes that although he lost a relatively small amount of money in this instance, the experience was formative and led him to develop a more disciplined approach to saving and investing. Now, at 59 years old, Puttonen reflects on the lessons learned from his early financial missteps and how these inform his teaching and writing on finance today.

Puttonen’s narrative serves as both a cautionary tale and a source of inspiration, illustrating the importance of financial literacy and the need for individuals, especially young investors, to educate themselves on the principles of saving and investing wisely. His journey from a novice investor to a knowledgeable finance professor highlights a transformative journey that resonates with many who have faced similar struggles in managing their finances.
