Built with Next.js and deployed on Vercel (Hobby plan), skhypremium.com is a real-time ADR premium calculator for SK Hynix ($SKHY / 000660.KS) investors.
What it does:
- Fetches live stock prices from both NYSE and KRX
- Calculates the ADR premium/discount ratio in real time
- Supports English and Korean
- Serverless Functions handle the FX rate + price calculations
It's been live for a few weeks and already getting organic traffic from Korean investors searching for "하이닉스 괴리율" (SK Hynix premium ratio).
Would love feedback from the community, and happy to write a fuller testimonial if the Vercel team is interested.
