Core Viewpoint - The article discusses the investment journey of the cosmetic company Proya, highlighting its significant profit growth and market valuation changes over the years, emphasizing the importance of understanding industry dynamics and making informed investment decisions. Group 1: Proya's Financial Performance - In 2017, Proya's profit was 200 million with a market capitalization of 5 billion, resulting in a dynamic P/E ratio of 25 times. By 2018, profits were projected to grow by 40-50%, leading to a lower P/E ratio of 17 times, indicating the stock was undervalued [2]. - By 2021, Proya's profit reached approximately 600 million, with a market capitalization of 40 billion, resulting in a dynamic P/E ratio of nearly 70 times. If profits continued to grow to 2 billion, the P/E ratio would drop to 20 times [4]. - Proya's profits increased from 200 million in 2017 to 1.5 billion in 2024, reflecting a consistent growth trend [11]. Group 2: Market Valuation and Investment Strategy - The article illustrates that selling Proya shares at a high P/E ratio (70 times) in 2021 could have led to missed opportunities, as the stock continued to perform well, while other sectors like real estate and banking saw significant declines [5]. - The author suggests that maintaining a position in high-growth companies like Proya, even at elevated P/E ratios, can be beneficial if the underlying business continues to grow [6]. - The article advises caution when the stock price reaches a certain threshold (30-40), as it may indicate a need to consider reallocating to higher dividend yield stocks [7]. Group 3: Industry Comparisons - Proya's performance is compared to other sectors, such as coal and liquor, where investments in companies with lower P/E ratios (like 7 times for coal) yielded substantial returns [5]. - Historical performance of other companies like Yunnan Baiyao and Heng Rui Pharmaceutical is referenced, showing that maintaining positions in leading companies can lead to significant long-term gains [9][10]. - The article emphasizes the importance of understanding industry trends and the potential for high-growth companies to maintain elevated valuations over time [8].
