STX EngineLtd (KRX:077970) delivers shareholders massive 38% CAGR over 5 years, surging 9.7% in the last week alone

Simply Wall St · 1d ago

STX Engine Co.,Ltd. (KRX:077970) shareholders might be concerned after seeing the share price drop 15% in the last quarter. But that doesn't change the fact that the returns over the last half decade have been spectacular. To be precise, the stock price is 403% higher than it was five years ago, a wonderful performance by any measure. Arguably, the recent fall is to be expected after such a strong rise. But the real question is whether the business fundamentals can improve over the long term.

Since the stock has added ₩136b to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...'

A Different Perspective

Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
