Watching the screens all day just doesn’t seem to work

Trying to make sense of the market noise

I spent most of last Tuesday staring at my brokerage app, watching the KOSPI slide down about 7.89% in what felt like a slow-motion car crash. It’s funny how you convince yourself that you’re prepared for these things until you actually see your portfolio bleeding red. I had been reading a lot about ‘Giant’s Portfolio’ and various quant strategies, thinking that if I just followed the data, I could sleep soundly. But when the headlines started popping up about semiconductor stocks crashing—Samsung Electronics down 9% and Hynix down 15%—all that rational logic just kind of evaporated. I kept checking the news to see if this was another one of those ‘Turbo Quant’ or ‘DeepSeek’ style noise events that analysts keep talking about, but the red numbers didn’t care about my intellectual analysis.

The gap between reading and doing

I’ve tried everything, really. I started with a simple ISA account, aiming for that tax benefit, then moved toward trying to pick stocks using criteria filters. I even spent about 40,000 KRW on a book about quant trading, thinking the math would save me from my own emotional impulses. The author, Kang Kook-hwan, made it look so straightforward. You set the rules, you backtest, you execute. Simple, right? In reality, setting up these automated conditions takes hours of staring at data points that never quite seem to align with what’s happening in the news cycle. There’s a constant, nagging feeling that I’m missing some hidden factor, or that my data-mined criteria are already outdated by the time I actually place a trade.

Getting tired of the volatility

Sometimes I wonder why I’m even doing this. My friend suggested I just stick to an old-fashioned monthly savings plan, but I couldn’t stop myself from thinking I could outsmart the market. I looked into Angel Robotics a few months ago when the stock price was buzzing, and I spent a weekend trying to figure out if it was a good entry point. I ended up doing nothing, which was probably for the best, but the uncertainty remains. It’s exhausting to balance a regular job with trying to track hedge fund-style long-short strategies in my spare time. I’m not a professional, and honestly, the deeper I dive into these ‘quant’ research papers, the more I realize that most of us are just playing with toys compared to the firms managing billions.

Why I keep looking at the charts

I still have the app installed, and I still check it during my lunch break. It’s almost a nervous habit now, like checking the weather even if you’re planning to stay inside all day. I saw something about Timefolio Asset Management using a single CIO structure to manage their hedge funds, and I found myself reading through their latest reports at 11 PM. It’s not like I’m going to change my entire strategy because of one company’s management style, but the obsession is real. Maybe I just like the feeling of being informed, even if that information leads nowhere. I remember when I first opened the account—I thought this would be my path to financial independence. Now, it feels more like a hobby that occasionally stresses me out.

The reality of the wait

I’m currently holding a few positions that are down, and I keep telling myself that time is the only thing that matters. But when the market drops, ‘long-term’ feels like a very abstract concept. I haven’t sold anything yet because I don’t know what else to do with the money. If I take it out, it just sits in a regular bank account earning almost nothing, which feels like losing money in a different, slower way. So, I wait. I keep the app, I keep reading the news, and I keep wondering if I’ll ever actually understand how the big firms navigate these ‘noise’ events without losing their minds. For now, I’m just waiting for the next cycle, still not sure if I’m actually investing or just participating in a very expensive form of entertainment.
