It is likely, but more confirming numbers are needed.

(Source: recent news headlines)

AMD: +5% rise reported

Chip prices: 10% increase reported

Nvidia and TSMC: reported to rise together

News of chip price hikes boosts expectations for supply and profitability.

How is the Korean market right now? (data time: 2026-09-22 14:30 KST)

KOSPI: 7,164.88 (+2.24%) [2026-09-22 intraday (unconfirmed)]

KOSDAQ: 845.45 (+1.10%) [2026-09-22 intraday (unconfirmed)]

Both indices are strong, and semiconductors and IT look likely beneficiaries.

US market and sectors?

US IT and semiconductors: +1.03%

US healthcare: +1.83%

US financials: -2.43%

Positive IT and semiconductor flows in the US are favorable for Korean chips.

Retail investor:

"Is it too late to enter now?"

There are more numbers to check.

Sector-wide persistence and actual earnings impact matter.

Implications

The 10% chip price increase report raises industry profitability expectations.

Individual strength in AMD spreads to peer-preference buying.

However, weakness in financials and real estate suggests imbalanced fund flows.

So, will it rise or fall

Downward pressure

• Financial sector, -2.43%, partial capital outflow pressure

• Real estate sector, -2.05%, signal of safe-haven reallocation

• Market uncertainty, intraday (unconfirmed) figures imply volatility is possible

Supportive factors

• KOSPI, 7,164.88 (+2.24%), overall buying sentiment is favorable

• US IT and semiconductors, +1.03%, global demand expectations

• AMD headline, +5%, stimulates forward-looking profitability expectations
