It is important to note that these indices consist of only 10 to 12 stocks. In addition, futures of the KRX BBIG mother index and two sub-indices (Secondary Battery and Bio) have been listed and operated since July of this year.
Hence, these indices provide relatively suitable conditions for ETF arbitrage.

In other words, we can aim for arbitrage using an ETF/NAV disparity. In particular, in Korea, we get tax-free benefits (no transaction tax) when selling ETFs.
For this reason, if a disparity rises above -0.25% (equivalent to transaction tax rate), we can consider a classic ETF arb setup.
We buy underlying securities and undergo ETF creation and redemption in the primary and then sell ETFs in the secondary market.
