US memory stocks melt down after South Korean bellwethers plummet

Tuesday was the first session South Korean traders could react to the US and Israeli strikes against Iran and the threat of a prolonged disruption to energy markets.

Memory stocks, the hottest pocket of the US stock market in recent months, are getting crushed, with Micron, Sandisk, Western Digital, and Seagate Technology Holdings all off at least 4.5% in premarket trading.

As of 6:35 a.m. ET, Micron and Sandisk have traded more dollar volume than any US stock outside of Nvidia, a signal of the highly motivated selling of these high-flying stocks.

The steep losses are linked to an ugly reopening for South Korean markets, home to high-bandwidth memory giants SK Hynix and Samsung, which tumbled 11.5% and 9.9%, respectively, in local markets on Tuesday.

South Korean markets were closed for a holiday on Monday, so this marked the first time traders were able to react to the US and Israeli strikes against Iran, which brings with it the threat of a prolonged disruption to energy markets. Such an outcome would be particularly challenging to South Korea, a major energy importer.

Foreign investors are leading the rout, pulling roughly $3.7 billion from KOSPI stocks on net, per Bloomberg. Retail traders in the East Asian country (dubbed “ants”) who have an affinity for leveraged products are reportedly buying the dip in a similar size.

The response to this negative catalyst is falling the hardest on SK Hynix and Samsung, whose humungous gains in 2026 pushed them to account for roughly 40% of the benchmark gauge. There may be some industry-specific chatter accentuating the losses, but at its core, this is just a parabolic trend breaking in the face of unexpected negative news.

As the fourth of famed Wall Street investment strategist Bob Farrell’s “10 rules for investing” dictates: “Exponential rapidly rising or falling markets usually go further than you think, but they do not correct by going sideways.”

Memory stocks had been the investing world’s favorite way to play the AI trade in recent months, as the outlook for a prolonged supply/demand imbalance sent prices of their offerings soaring. This dynamic prompted furious upward revisions to earnings and sales estimates for the cohort, which trade at modest valuations relative to most of the tech universe.

Oil to lows and stocks to highs of day after President Trump says US will insure and escort oil tankers through the Gulf

West Texas Intermediate futures dipped to their lowest level of the day while the SPDR S&P 500 ETF continued to pare losses after US President Donald Trump ordered immediate action to improve the flow of oil to global markets, as the US-Iran conflict caused shipments through the Strait of Hormuz to slow to a crawl.

In a Truth Social post, the president said the US International Development Finance Corp. would provide “political risk insurance and guarantees for the Financial Security of ALL Maritime Trade, especially Energy, traveling through the Gulf,” adding that the US Navy would escort tankers through the Strait of Hormuz as soon as possible, if necessary.

Bloomberg’s Javier Blas explained that having oil-producing countries in the region able to reload crude on tankers is critical to avoiding production shut-ins.

Of course, there is a risk of unintended consequences from a heightened US presence in the region’s most strategically important area, from the perspective of global markets, during a time of kinetic military action. US naval escorts through the strait could dramatically increase the risk of an incident that massively escalates the conflict.

Versant climbs in its first quarter after spin-off, announces dividend and $1 billion stock buyback

Versant Media, the owner of cable TV assets including CNBC, MS Now, and Golf Channel, reported its first earnings since spinning off from Comcast earlier this year. The stock climbed 3% after markets opened.

Investors appear to like Versant’s $1 billion stock buyback plan and its newly announced quarterly dividend of $0.375 per share.

Versant reported Q4 revenue of $1.55 billion, shy of the $1.56 billion expected by analysts polled by FactSet. The company posted earnings of $0.72 per share in the quarter, below estimates of $0.96 per share.

MS Now, formerly MSNBC, was the most watched news channel on election night in November, Versant said. The network will launch a direct-to-consumer platform later this year.

Energy price spike on Mideast war has traders betting on no Fed cuts through June

A war in the Middle East, and the resultant upward pressure on oil prices, has caused traders to reverse bets that the Federal Reserve will cut interest rates in the first half of this year.

The prediction market-implied odds of a rate cut in June are less than 45% on Tuesday morning. Last week, the odds of a rate cut in June were around 60%. This comes as US national average gasoline prices rose 3.7% on Monday, their biggest one-day jump since 2005, according to data from the American Automobile Association.

In the short term, higher energy prices put upward pressure on inflation and downward pressure on economic activity. Higher gasoline prices reduce households’ ability to spend more on other discretionary goods and services.

Normally, Fed officials would want to “look through” the impact of higher energy prices as a temporary source of upward pressure on inflation that is not indicative of the underlying trend. That’s why energy (and food) prices are stripped out of core inflation. However, this time might be different:

  • Inflation has run above the Federal Reserve’s target for a prolonged period.

  • The central bank is a little scarred by the un-transitory and severe postpandemic inflation (which was meaningfully accelerated by Russia’s invasion of Ukraine).

  • Monetary policymakers were already signaling that the stabilization in jobs data and previous cuts, which brought their policy rate closer to a neutral setting, meant the bar for additional easing was higher.

“I think the Fed will be reluctant to elevate growth over inflation risks right now,” wrote Neil Dutta, head of US economics at Renaissance Macro Research. “Cuts have been a close-call as it is; thus, it’s tough to look through inflation when you are coming off a period of high inflation.”
