Summary

Park Se-ik argues that ordinary investors can simply hold plain 1x ETFs but should avoid 3x leveraged ETFs, using semiconductor and Korea examples to show how leverage and volatility decay destroy returns. He contrasts a steadily rising 1x Philadelphia Semiconductor Index ETF with severe drawdowns in the 3x semiconductor ETF and KORU. He adds that leverage may be acceptable for professionals but is a dangerous gambling-like tool for retail investors.

  • Reviews a plain 1x Philadelphia Semiconductor Index ETF that rose from 185 at its 2022 high to 270 in 2024 and 655 recently.
  • Contrasts it with the 3x semiconductor ETF, which fell from $74 to $6, recovered to $70, then dropped to $8 and remains volatile.
  • Shows KORU underperforming the KOSPI because of leverage decay across 2018, 2020, 2021, and the recent rally.
  • Calls 3x leveraged ETFs gambling products disguised as stock investment and argues they should be avoided or banned.
  • Notes leverage is acceptable mainly for professionals because losses are magnified when used incorrectly.
  • Recommends daily newspaper reading as an investment habit.

Avoid 3x semiconductor ETF; decay destroys.
Park contrasts a plain 1x ETF tracking the Philadelphia Semiconductor Index, which rose from its 2022 high of 185 to 270 in 2024 and 655 recently, with the 3x semiconductor ETF, which collapsed from $74 to $6, recovered to $70, fell to $8, then hit $300 and is now $129. He argues the 3x product is gambling disguised as stock investment because leverage and volatility decay destroy value even when the underlying index uptrends, and it should be avoided or even banned.

Long 1x Philadelphia semiconductor ETF.
Park says ordinary retail investors can freely use the plain 1x ETF tracking the Philadelphia Semiconductor Index, which he calls excellent and shows is in a structural uptrend, rising from 185 at the 2022 high to 270 in 2024 and 655 recently. The edge is that owning the 1x semiconductor index avoids the volatility decay and catastrophic drawdowns of the 3x version.

Avoid KORU; leverage decay destroys value.
Park shows KORU, the 3x South Korea ETF, traded at $36 when KOSPI hit 2,600 in early 2018, fell to $2 during the 2020 COVID crash, and even when KOSPI reached 3,300 in 2021 the ETF was lower than when the index was at 2,600; it then collapsed to $1.35 and after a recent rally to $63 is still down roughly 72% from its high. This demonstrates structural 3x decay: the product fails to capture the long-term Korean index recovery and is a gambling-like destruction of capital.
