Hello
Hello, my name is Sungyeob Lim, and I live in South Korea. I have long been interested in investing in U.S. equities. Many Korean investors build their portfolios around U.S. stocks, and I am one of them.
Why this became personal
As a follower of the Bogleheads philosophy, I often questioned whether I was truly living up to John Bogle's values and principles. In practice, investing consistently according to one philosophy is harder than it seems. At times, I became overly concentrated in stocks like TSLA, as many Korean investors did. At other times, I invested most of my income into broad ETFs such as VOO or VTI. These high-volatility decisions led to repeated setbacks in my portfolio.
What I learned
Investing in broad market ETFs like VOO, SPY, or VTI is reasonable, and I am not suggesting that this approach is wrong. However, reality is often more nuanced. Each person's financial situation, time horizon, and goals are different. Some investors need stable dividend income. Others may not have decades to wait for long-term compounding to fully unfold.
Why Portwise exists
Every portfolio carries both strengths and weaknesses. These characteristics are ultimately expressed as risk. I wanted to simplify the process of assessing portfolio risk and present it in a way that investors can clearly understand. If you can quantify the potential risk within your portfolio, you can better evaluate whether its behavior truly aligns with your personal investment values.
That is the mission of this app.
I want to be clear:
- This platform does not provide portfolio recommendations.
- It does not function as a brokerage.
- It is designed solely to help you understand your current portfolio more objectively.
- The decision of what to do next remains entirely yours.
