description: "$XL2CSOPHYNIX(07709.HK) Observing the patterns and characteristics of the Southern DCE Hynix 2x Leveraged ETF over more than two years:When the K-line chart reaches a price level around 20-something, it is the price with the highest probability for each significant rebound. Last time, it surged from the 20-something range to over 170. The main body ETF's erosion degree is due to the unsynchronized opening times between South Korea 🇰🇷 and Hong Kong 🇭🇰 regions, leading to a relatively medium-to-high speed fluctuation trend. The main share price of SK Hynix in South Korea 🇰🇷 has already exceeded $1,000 per share. Relatively speaking, according to this ETF linked by ChinaAMC in Hong Kong, the price is still quite cost-effective and cheap, but the volatility oscillation erosion rate while holding will also be higher."
