KOSPI Composite Index Surges Above 4,100 as Global Markets Position for Fed Rate Cut (5

Published: December 7, 2025

The Korea Composite Stock Price Index (KOSPI) ended the week of 5–7 December 2025 as one of the standout performers among major world indices, reclaiming the 4,100 level and extending what has become a world‑beating year for South Korean equities.

On Friday, 5 December, the KOSPI closed at 4,100.05, up 71.54 points (+1.78%) on the day and roughly 4–4.5% higher for the week, its strongest weekly performance in months. ^[1] While trading was closed over the weekend, 6–7 December brought a flood of fresh forecasts and strategy notes as analysts weighed three big drivers:

A likely U.S. Federal Reserve rate cut next week, already heavily priced into global markets. ^[2]
A still‑booming AI and semiconductor cycle, now accompanied by open debate over whether valuations have gone too far. ^[3]
Korea’s own reform and stimulus agenda, with President Lee Jae‑myung repeatedly tying his political project to a long‑term goal of pushing the KOSPI toward 5,000 points. ^[4]

Below is a detailed look at what happened in the KOSPI and how it fits into the broader picture of world indices from 5–7 December 2025.

KOSPI Weekly Snapshot: Above 4,100 and Still a Global Outperformer

Friday’s close: 4,100 and a strong weekly rebound

Market data from Macromicro and other providers show the KOSPI finishing Friday, 5 December 2025, at 4,100.05, up from 4,028.51 the previous session. ^[5] Business Today’s weekend wrap notes that the index rebounded to 4,100.05, gaining 71.54 points (1.78%) on Friday, after a week of choppy sessions that included modest gains on 2–3 December, a small pullback on the 4th, and then a sharp rally into the weekend. ^[6]

Morningstar data indicate that the KOSPI rose about 4.4% over the week, marking its biggest weekly percentage gain in roughly a year and underscoring how quickly sentiment has swung back after November’s correction. ^[7]

Valuations: richer than before, still cheaper than many peers

According to CEIC, the KOSPI’s price‑to‑earnings (P/E) ratio stood at around 18.6 on 5 December, down from a peak above 33 in 2021 and well above the single‑digit lows seen in 2022. ^[8] For comparison, MSCI data place the MSCI World Index P/E at roughly 24.4, with a forward P/E around 20.4 as of late November. ^[9]

That leaves Korea more expensive than in the depths of the “Korea discount” era but still valued below many developed‑market peers, supporting the narrative that there is room for further rerating if reforms stick and earnings hold up. ^[10]

Year‑to‑date performance: one of the best major markets on earth

Two separate in‑depth features—one from Singapore’s Business Times and another from BusinessMirror (via Bloomberg)—highlight just how extreme this rally has been. They estimate that:

The KOSPI started 2025 near 2,400, and has since surged roughly 60–70%, making it one of the best‑performing major benchmarks globally and pointing to the strongest annual gain in about 25 years. ^[11]
Much of that jump has been driven by semiconductor heavyweights Samsung Electronics and SK Hynix, amplified by the government’s explicit “KOSPI 5,000” ambition and a series of market‑friendly reforms. ^[12]

In other words, even before this week’s bounce, Korea was already atop the global leaderboard. The latest move above 4,100 simply confirms the KOSPI’s status as the flagship of 2025’s equity bull market.

What Drove Friday’s KOSPI Rally? Autos, Chips and Foreign Buyers

Autos steal the spotlight

Several outlets, including Business Today and Korea’s financial press, agree that automakers led Friday’s upswing. ^[13] Korean car stocks surged after signs that U.S. tariff risks on Korean auto exports could be less severe than feared, easing a major overhang for the sector. ^[14]

This mattered for the index because autos, alongside semiconductors, are among Korea’s largest export engines—and heavyweights in the KOSPI. A policy‑driven relief rally in these names quickly translated into a broad‑based move in the benchmark.

Foreign and institutional flows return

Maeil Business Newspaper (MK) reports that both foreign investors and domestic institutions bought more than 1 trillion won each in Korean equities on 5 December, helping propel the KOSPI back above the 4,100 level for the first time in 16 trading days. ^[15] That foreign‑institutional “double bid” was powerful enough to overwhelm continued profit‑taking by local retail traders, who have been locking in gains after the blistering year‑to‑date run. ^[16]

This pattern—local traders selling into strength while institutions and offshore funds buy dips—has become a recurring theme of the 2025 rally and is a key reason why volatility has increased but sell‑offs have been short‑lived. ^[17]

AI and chips: growth story vs. valuation anxiety

The AI semiconductor boom remains the backbone of the KOSPI story, but the conversation has shifted from pure excitement to a more nuanced discussion of valuation risk.

A widely shared Reuters interview on 5 December quoted SK Group chairman Chey Tae‑won as saying that while the AI industry itself is not in a bubble, AI‑linked stocks have “risen too fast and too much,” making a correction normal and even healthy. ^[18] SK Hynix, for example, has gained more than 200% in a year amid an AI‑driven “supercycle” in high‑end memory. ^[19]

This tension is reflected in MK’s weekend analysis:

One feature notes that the KOSPI recently surpassed its all‑time high above 4,200 before slipping back toward 4,000, as global worries over an AI “bubble,” uncertainty over interest‑rate policy timing, and even crypto‑market weakness triggered bouts of profit‑taking. ^[20]
Another piece argues that only Samsung Electronics and SK Hynix are truly carrying the index, and calculates that for the KOSPI to reach 5,000 on the back of those two names alone, each would need to rally nearly 70% from the 5 December close—well above the consensus target prices of local brokerage houses. ^[21]

In short, chip giants remain the engine of the rally, but also its main vulnerability.

KOSPI vs. World Indices: Asia’s Star in a Fed‑Driven Global Rally

Asia on 5 December: KOSPI shines while the Nikkei stumbles

A Reuters Asia markets wrap describes Friday as an “upbeat” session for most of Asia, even as Japan’s Nikkei 225 fell around 1.3% on concerns that the Bank of Japan could hike rates later this month. In that context, South Korea’s benchmark index rose about 1.4%, and MSCI’s Asia‑Pacific ex‑Japan index gained around 0.4%. ^[22]

That left the KOSPI not only up sharply on the day, but also outperforming many regional peers that are still grappling with softer domestic growth, China‑related weakness or more hawkish central banks. ^[23]

Wall Street and Europe: grinding higher into a likely Fed cut

Across the Pacific, U.S. stocks closed Friday with modest gains:

S&P 500: up 0.2% on the day and 16.8% year‑to‑date, just shy of its record high.
Dow Jones Industrial Average: up 0.2% on Friday and 12.7% year‑to‑date.
Nasdaq Composite: up 0.3% on the day and 22.1% higher for 2025. ^[24]

Reuters notes that global equities, measured by MSCI’s all‑country index, also edged higher, with Wall Street logging a second straight week of gains. European shares were roughly flat on the day but managed a small weekly advance. ^[25]

Valuation context: world vs. Korea

The MSCI World Index currently trades on a P/E multiple above 24 and a P/B around 3.9, with a forward P/E just over 20. ^[26] Meanwhile, CEIC’s data put South Korea’s broad market P/E near 18.6, and Korea’s central banks and policymakers continue to reference the long‑discussed “Korea discount” relative to U.S. and European markets. ^[27]

Even after a roughly two‑thirds rally this year, KOSPI valuations remain below those of many developed markets, which is one reason foreign managers argue the index could rally further if governance reforms and shareholder‑friendly policies continue. ^[28]

Macro Backdrop: Fed vs. BOJ, Dollar vs. Won

Fed cut expectations anchor global risk sentiment

Global markets are now almost fully aligned around a 25‑basis‑point Federal Reserve rate cut at the conclusion of the 9–10 December FOMC meeting, with CME’s FedWatch tool implying probabilities near 90%. ^[29]

Reuters reports that:

U.S. PCE inflation for September came in at 0.3% month‑on‑month, in line with expectations. ^[30]
U.S. consumer sentiment has stabilized, even as worries about prices and the labor market linger. ^[31]

Analysts quoted in both global and Korean outlets argue that, with the Fed having signaled cuts well in advance, equities have already priced in a dovish outcome—a point that Korean strategists are emphasizing as they warn against assuming the Fed decision alone can keep pushing the KOSPI higher. ^[32]

BOJ divergence and regional spillovers

While the Fed is expected to ease, the Bank of Japan is seen tilting hawkish, with Japanese government bond yields hitting their highest levels since the mid‑2000s as markets brace for a possible rate hike. ^[33]

This divergence—Fed easing vs. BOJ tightening—has:

Hammered the Nikkei in recent sessions. ^[34]
Supported the yen, complicating carry trades and adding another layer of volatility to Asian asset prices. ^[35]

For Korea, stronger yen and expectations of lower U.S. rates are generally positive for export competitiveness and risk appetite, but the cross‑currents make the region’s rate and FX backdrop unusually complex heading into year‑end.

Domestic Sentiment (7 December): “Breath‑Taking” Pause, Not the End of the Bull

A major MK weekend feature published on 7 December frames November’s pullback as a “breath‑taking process,” not the end of the bull market. ^[36] The piece summarizes the consensus among large Korean brokerages:

The KOSPI’s recent drawdown—peaking at roughly –9.8% during the correction—matches the typical magnitude of past pullbacks within bull markets. ^[37]
Multiple market pillars are improving simultaneously:
- Liquidity resumption, with the Fed ending quantitative tightening and the U.S. Treasury managing its cash account more aggressively.
- Policy momentum from the Lee administration, including a roadmap to pursue MSCI “advanced market” status, compulsory cancellation of treasury shares, and more generous treatment of dividend income. ^[38]
- Corporate earnings (EPS) upgrades, particularly in semiconductors and autos. ^[39]

Yuanta Securities’ research center is cited as targeting a December KOSPI peak around 4,200, explicitly tying that to the combination of Fed policy, U.S. liquidity trends and domestic reforms. ^[40] Samsung Securities, meanwhile, emphasizes that the shape of the Fed’s “dot plot” for 2026—the longer‑term rates path—may be more important than the December cut itself, because it will frame the durability of the global liquidity tailwind. ^[41]

Short‑Term KOSPI Forecasts (5–7 December): Trading Range, Santa Rally, and the 5,000 Debate

3,760–4,240 near‑term range, with a possible push toward 4,700

A Korea Herald article dated 7 December, headlined “Will Kospi see Santa Claus rally this year?”, lays out the core tactical forecasts now circulating among local strategists:

Base‑case trading band: many analysts project the KOSPI to oscillate between 3,760 and 4,240 points in the near term, reflecting both strong year‑to‑date momentum and mounting valuation concerns. ^[42]
Bull‑case scenario: optimists argue that if the Fed delivers a clean cut, AI‑related tech gains continue, and domestic policies land well, the index could test as high as 4,700 into early 2026. ^[43]
Year‑end targets: more conservative houses see the KOSPI ending between 4,100 and 4,200, essentially near its current level. ^[44]

The same article notes that the KOSPI has risen about 63.6% from January to November, the steepest gain among the main indices of G20 countries, and that this extraordinary run has compressed the market’s P/E even as EPS has surged—evidence that investors are still cautious about extrapolating earnings growth. ^[45]

KOSPI 5,000: aspiration vs arithmetic

The politically charged “KOSPI 5,000” slogan remains central to the domestic narrative. President Lee has openly tied his reform agenda to the idea of driving the benchmark to that milestone. ^[46]

However, a detailed MK breakdown published on 7 December underlines how demanding the math has become after this year’s run:

If only Samsung Electronics and SK Hynix were to power the move, each stock would need to climb roughly 70% more from their 5 December closing prices for the index to reach 5,000—well above the average target prices compiled by local brokerages. ^[47]
Even in scenarios where multiple sectors participate, strategists argue that further rerating of “old economy” sectors—banks, utilities, industrials, and domestic consumption—would be necessary to get the index meaningfully closer to that level. ^[48]

At the same time, global houses like JPMorgan and Citigroup have reportedly raised their KOSPI targets toward the 5,000–5,500 area by the end of 2026, citing structural reforms and the AI chip super‑cycle, though they stress this is a multi‑year, reform‑dependent scenario rather than a straight‑line forecast. ^[49]

2026 macro backdrop: budget, tariffs and growth

Looking beyond December, a recent AInvest analysis of South Korea’s 2026 budget highlights a planned KRW 728 trillion spending program aimed at innovation‑led growth, with heavy investment in AI, semiconductors and robotics, all while navigating U.S. tariff pressures. ^[50]

Combined with the Bank of Korea’s modest upgrade of its 2026 growth forecast to 1.8%, Bloomberg‑cited economists argue that Korea’s real economy is doing better than feared, supported by exports of chips and autos and a wealth effect from rising stock prices—though structural issues like demographics and high household debt still cap the long‑term growth ceiling. ^[51]

Key Themes to Watch After 7 December

For investors, policymakers and anyone tracking the KOSPI vs world indices, the period from 5–7 December crystallized several themes that will likely dominate into year‑end and early 2026:

Central‑bank divergence
- Fed easing (or at least a softer stance) is broadly supportive for risk assets worldwide. ^[52]
- BOJ normalization and higher JGB yields are reshaping global carry trades and adding volatility to Asia. ^[53]
Leadership concentration vs. broadening rally
- The rally is still heavily concentrated in a handful of AI‑linked tech giants. ^[54]
- Autos’ outperformance this week shows what a broader sector rotation could look like, but sustained follow‑through from banks, utilities, and domestic cyclicals is still missing. ^[55]
Valuation tightrope
- With the KOSPI P/E near 18–19 against MSCI World’s mid‑20s, Korea is no longer deeply discounted, but still cheaper than many developed peers. ^[56]
- AI pioneers acknowledge valuations may have overshot, raising the risk of a sentiment‑driven correction even if the fundamental growth story remains intact. ^[57]
Policy as performance driver
- Corporate‑governance reforms, tax tweaks, and a push toward MSCI “advanced market” status have become core to the bull thesis, increasing the sensitivity of the KOSPI to political headlines and legislative timelines. ^[58]
Santa rally vs. fatigue
- Local strategists are divided: some expect a classic Santa Claus rally to push the index further above 4,100, while others argue that after a ~60–70% YTD surge, fatigue and risk management could dominate, especially if the Fed under‑delivers or AI valuations wobble again. ^[59]

Bottom Line

From 5–7 December 2025, the KOSPI Composite Index reasserted its role as one of the world’s hottest stock markets, breaking back above 4,100 on the strength of autos, semiconductors, and renewed foreign buying, even as global investors brace for a pivotal Federal Reserve meeting.

Compared with world indices, the KOSPI now offers a rare combination of:

Top‑tier year‑to‑date performance,
Valuations still below many developed markets, and
A dense cluster of policy, AI and macro catalysts that can swing sentiment quickly.

Whether the coming weeks deliver a full‑blown Santa rally or just a sideways consolidation within the 3,760–4,240 band, the consensus across research published between 5 and 7 December is clear: this is still a bull market—just one that is maturing, more policy‑sensitive, and increasingly dependent on broadening beyond a handful of mega‑cap chip names. ^[60]
