The Reality of Chasing QQQ and US Tech Stocks: Why Everyone Is Rushing to the US Market

The Migration to the US Market and the QQQ Trap

I have seen a lot of people in my circle recently pivot from the domestic KOSPI index to US-listed ETFs like QQQ. It feels like an inevitable reaction to the stagnation we see locally. When I first considered moving a chunk of my portfolio to US tech stocks, I expected a smooth transition into ‘safe’ growth. The reality, however, was quite different. I spent about two weeks obsessing over exchange rates, trying to time my entry when the dollar was slightly weaker. In the end, the fluctuation in the dollar-won rate often wiped out the gains I made on the index itself. This is where many people get it wrong; they treat foreign investment like a simple switch, ignoring that you are essentially taking a position on currency as much as you are on tech stocks.

My Personal Experience with Leveraged Tech ETFs

There was a moment about a year ago when I looked at the performance of leveraged products like the ProShares UltraPro QQQ ETF. Seeing it jump 3% in a single day while the base QQQ moved less than 1% was intoxicating. I put a small portion of my ‘play money’—roughly $2,000—into it. It worked beautifully for three days. But then a standard CPI release triggered a market pullback, and the decay from the daily reset hit harder than I anticipated. I exited with a minor loss, but the stress was not worth the 4% gain I had initially chased. In real situations, this tends to happen: the leverage decay eats your performance silently while you are waiting for a recovery that might not come as quickly as the math suggests.

The Trade-off: Growth vs. Emotional Stability

Many younger investors ask if it is better to start small, perhaps putting 2,000 won into VOO and 1,000 won into QQQ through automated savings apps. My take? It depends entirely on your sleep quality. VOO gives you the broad S&P 500 safety, while QQQ leans heavily into tech. If you are the type who checks your portfolio every hour, the volatility of QQQ will drive you insane during a correction. The common mistake is assuming that because QQQ has historically outperformed, it is ‘better’ for everyone. It is not. It is only better if you have the stomach to watch it drop 20% without selling in a panic.

Hidden Costs and Complexities

We often ignore the transaction fees and the tax implications of trading US stocks. For a small portfolio, these costs are negligible, but once you start moving significant capital, the landscape changes. I once spent a morning calculating the hidden costs of trading through various platforms, and honestly, the commission differences between standard brokerages are not the primary issue—it is the hidden spread and the tax reporting that become a headache. I’m still not entirely sure if the automated ‘stock gathering’ features are efficient for larger sums; sometimes, I think doing nothing and holding a single broad ETF is a far superior, albeit boring, strategy.

A Reality Check on Expectation vs. Reality

I expected that holding QQQ would make me feel like a seasoned ‘tech investor.’ Instead, I mostly just feel anxious whenever interest rates become a topic of conversation. The expected result—consistent double-digit growth—hasn’t always manifested linearly. Sometimes, the market just goes sideways for months, and holding tech-heavy assets during those times is tedious. There is a palpable hesitation in my own strategy now: should I keep adding to my growth position, or should I buy more dividend-paying assets just to feel like I’m getting something back while waiting for the next bull run? It is an uncertain trade-off that rarely has a ‘perfect’ mathematical answer.

Who Should (and Should Not) Do This

This advice is primarily for those with a long-term horizon who understand that the US market is not a magic ATM. If you are looking for quick, reliable returns to cover short-term expenses, do not follow this path—the volatility of tech-heavy ETFs will likely leave you frustrated. If you have an extra 10–15 years, starting a simple DCA (Dollar Cost Averaging) approach is a reasonable step, but you must accept that there will be years of stagnation. My suggestion? Stop looking at the daily charts for a month. A realistic next step is simply checking your brokerage’s tax reporting requirements before you move another dollar into these accounts, rather than focusing on the next ‘hot’ sector ETF. Note: This assumes the global economic environment remains relatively stable, which is a major, and perhaps naive, assumption.
