📊 POSCO Holdings, 330,000 KRW range battle and review of lithium carbonate expansion - 2026.09.04

Hi, it’s Danggeuni, someone who truly cares about chart numbers. POSCO Holdings rose sharply on September 3, then was pushed back to the 330,000 KRW range in just one day, making this a good time to check with the numbers how steel and lithium expectations collide with actual price movements. The key does not seem to be simply whether the rebound continues, but how concretely the lithium business’s production format and schedule are taking shape. 📊

The brakes came on just one day after the September 3 surge

POSCO Holdings closed at ₩342,000 on September 3, 2026, up +3.64% from the previous day ^[3]. But on September 4, it rose from an opening price of ₩342,000 to a high of ₩345,000, then passed through a low of ₩334,500 before closing at ₩336,500. The change was -1.61%, with trading volume at 214,652. Rather than carrying over the previous day’s momentum, selling emerged at the intraday high and the stock returned to an 330,000 KRW range pattern ^[2].

The article also reported that after rising more than 3% the previous day, the stock climbed to ₩345,000 early in the September 4 session before falling back to the 330,000 KRW range ^[2]. Wow, looking only at the chart, market sentiment genuinely seems to have changed completely in a single day. However, these numbers alone do not support the conclusion that the performance of the steel or lithium businesses has changed. It looks cleaner to read the current price range as an area where expectations and profit-taking are colliding.

The new lithium point this time 🧪

The new factor is Stage 3 and Stage 4 of the Argentine salt-lake lithium project. According to related reports, POSCO Holdings is reviewing a plan to reflect annual lithium carbonate production capacity of 25,000 tons for each stage, with target operation dates of 2030 for Stage 3 and 2033 for Stage 4 ^[1].

You shouldn’t look at these numbers superficially. The key expressions are ‘under review’ and ‘target date.’ This does not mean production has already begun; it was reported as a stage in which the company is examining a plan to incorporate lithium carbonate production capacity into its business strategy ^[1]. Moreover, the schedule is divided between 2030 and 2033, so this should be viewed in connection with long-term business value rather than as a factor immediately reflected in earnings. Seriously, if you focus only on the large numbers and miss the timeline, the interpretation gets tangled.

The gap between steel and lithium expectations and the price response 📌

Another analysis reported on September 3 highlighted the possibility of a POSCO Holdings rebound from the perspectives of a steel recovery and the lithium business ^[4]. However, this is the media outlet’s analysis, not a result confirmed by the company. Considering the stock’s movement on September 4—reaching ₩345,000 intraday before closing at ₩336,500—it is difficult to conclude that the market is valuing steel and lithium in only one direction.

Danggeuni sees the current trend as meaning that ‘the lithium production format and schedule are the next verification checklist.’ The key angle is whether the review of lithium carbonate production capacity leads to actual business progress, and how consistently expectations for a steel recovery are reflected in price movements. In particular, while trading continues in the 330,000 KRW range, it seems important to watch whether the gap between the high and closing price, changes in trading volume, and newly confirmed business schedules move together. The numbers on the box may look neat, but if the contents inside are empty, it is difficult to hold for long.

Chart notes and remaining questions 🎯

My trademark is no full buying, no full selling, act only when the support line breaks. The support line here does not mean a confirmed figure, but a zone where the market has repeatedly reacted in the recent price movement. Based on the current information alone, it is impossible to determine the direction of a specific price; the accurate point is simply that the September 4 low of ₩334,500 and close of ₩336,500 have been recorded as the next price-check zones.

In the end, there is one question remaining. How will the lithium carbonate production capacity being reviewed with targets of 2030 and 2033 become more concrete alongside additional information, and how will the gap between steel expectations and actual price responses narrow in the meantime? The numbers have already fluctuated; what is needed now is not expectation, but verifiable progress.
