AI SUMMARY — SK hynix and memory stocks face bearish pressure as new South Korean regulations will lock out new investors from leveraged ETF trading for 5 days starting the 19th, reducing retail demand just as volume is already declining. Additional headwinds include SK hynix rejecting key technical levels and Korean retail investors shifting capital to US stocks, creating a convergence of negative factors over the next 5 days.

Read the wording of this news report very carefully:

From the 19th, new investors will not be joining the degenerate leveraged ETF party for 5 full days. This isn't a 5 hours course on trading, it locks you out of trading for 5 full days. Furthermore, they will have to register and be approved to trade these products and inevitably, some won't make meet the standards.

SK hynix day chart

We can talk about the fact that SK rejected off the 20/50 SMAs (which isn't the case for MU/SNDK), bearish in and of itself, but the more important thing is that volume is already not coming back the way it is for Micron/Sandisk and the paper trading requirement hasn't even taken effect yet.

Add in the fact that Koreans are starting to buy US stocks instead of their own market:

So on one hand these ants thinking they're escaping the unfair Korean market are turning to US stocks without realizing that Korea/DRAM/SK hynix/memory/semiconductors are all correlated as 1 trade. On the other hand you have 5 upcoming days of no leveraged ETF inflows into SK hynix from new investors which likely causes KOSPI to decline which sets off the algorithmic associations between all the stocks in this sector.

My prediction is that for the next 5 days this sector suffers significant volatility, probably to the downside, and we likely get US institutions happy to distribute into Korean buying pressure, rugpulling them on US stocks just like they rugpulled them with Samsung/SK. We could also get Koreans who turned to US stocks changing their mind because all the algorithmic association brings that whole memory/semiconductor sector down, and that puts more selling pressure on those US stocks, which causes more algorithmic selloff of Korean stocks, etc in a feedback loop.

My position: 1,000 shares sold short of KORU at 19.58 per share ($19,580 exposure). Very risky because market hours don't overlap and it'll gap up over my stop if I'm wrong. NFA.
