00:02You're listening to AI Prism from Seoul Economic Daily.
00:06Three numbers before the open.
00:0980%, 6 trillion won, and 47 won.
00:15Samsung just hit an 80% yield on HBM4,
00:20the golden yield threshold the whole industry watches.
00:25Foreign investors dumped nearly 6 trillion won of Korean chip stocks
00:29in a single week.
00:31The won just posted its widest monthly swing
00:34since the 2009 financial crisis.
00:37And covered call ETFs are pulling in cash
00:40at a pace up 70% from last year,
00:44as traders brace for more CHOP.
00:47It's Monday, August 10th.
00:49Here's what today's story could mean for the Korean market.
00:53Samsung's HBM4 yield breakthrough
00:56landed the same week foreign investors pulled almost 6 trillion won
01:01out of Korean chip stocks.
01:03That combination is reshaping how traders read the semiconductor cycle
01:08heading into the back half of the year.
01:10Meanwhile, the won's wildest swings since the financial crisis
01:15are adding another layer of noise
01:17to every position built around Korean equities.
01:20Here's what the numbers show.
01:23Samsung's HBM4 yield reached roughly 80% this month,
01:28up from under 60% at the February launch,
01:31the level the industry calls golden yield
01:34because it marks stable, high-volume output.
01:38Samsung plans to triple its third-quarter HBM4 revenue
01:42from the prior quarter
01:43and push HBM4 past 60% of total HBM sales in the second half.
01:50UBS projects Samsung's HBM bit shipment share
01:54will hit 41% next year,
01:57edging past SK Hynix's 39%,
02:00a reversal from SK Hynix's 48% lead this year.
02:05Foreign investors sold 5.92 trillion won
02:10of Samsung Electronics, SK Hynix,
02:13and three other chip names between August 3rd and 7th,
02:17rotating instead into Samsung's C&T,
02:20Celtrion, and Hanwha Aerospace.
02:23The won moved an average of 47 won a month so far this year,
02:28the widest swing since 2009's 61.2 won,
02:33and just short of the 1997 to 98 crisis years.
02:38Covered call ETF assets in Korea
02:41reached 25.99 trillion won as of August 7th,
02:46up 70% from 15.04 trillion won at the end of last year.
02:52So what does this mean for the Korean market right now?
02:55Earlier, we said foreign investors
02:58dumped nearly 6 trillion won in chip stocks.
03:01Here's what that actually means for you.
03:04That money didn't leave the market.
03:06It rotated into bio, defense, and autos,
03:10so the sector story matters as much as the index level.
03:14Samsung's yield breakthrough is a genuine supply-side shift,
03:18not just a headline,
03:20since foreign ownership in both Samsung and SK Hynix
03:24is sitting near yearly lows.
03:26And with won volatility at levels unseen
03:29since the financial crisis,
03:31position sizing around FX-sensitive names
03:34deserves as much attention as the chip cycle itself.
03:37Here's what to watch.
03:40SK Hynix's fourth quarter HBM4 e-supply ramp
03:44against Samsung's accelerated timeline.
03:48Foreign ownership trends in Samsung and SK Hynix
03:51as both sit near yearly lows.
03:54And whether the won breaks below 1,400
03:57or holds range around the Fed's next move.
