Why Are Leveraged ETFs like 7709 Inherently Negative EV Products?
This article argues that the SK H力士 2x Leveraged ETF (7709) is fundamentally a negative expected value (EV) product, rather than simply a "double SK H力士" investment. Its core issue stems from its daily rebalancing mechanism to maintain a 2x leverage target.
After a price move, the fund must buy more after a rise or sell after a fall to readjust its leverage, creating a systematic pattern of buying high and selling low. This introduces a "delay loss": it always reacts to past price changes, missing potential gains from adjusting earlier during an uptrend and suffering greater losses from adjusting later during a downtrend.
While more frequent intraday rebalancing would improve returns in strong, smooth trending markets by reinvesting profits or cutting losses sooner, it also dramatically increases volatility drag (frictional losses) during choppy, oscillating markets due to more frequent high-buy/low-sell trades.
The author draws a parallel to an option seller who delta hedges (short gamma), which involves similar "buy high, sell low" dynamic hedging. However, unlike an option seller who receives upfront premium (IV and theta) as compensation for this risk, the leveraged ETF investor receives no such compensation. Instead, they bear all the path-dependent volatility decay, plus additional costs like swap/derivatives financing, management fees, and trading slippage.
Thus, the product's return profile can be framed as: 2x directional return minus realized variance drag minus financing costs minus derivatives costs minus management fees minus transaction costs. For the investor to profit, SK H力士's price must not only rise significantly but do so in a strong, sustained, and smooth trend to overcome these inherent structural costs. High volatility and frequent price reversals are particularly damaging.
The article also notes that while the ETF has no explicit liquidation line like perpetual futures, avoiding a sudden "blow-up," its net asset value can still decay towards zero over time through this combination of volatility drag and fees. For experienced traders, directly managing leverage via perpetual contracts may offer more control and potentially lower costs than this packaged, mechanistic product.
