Summary

Oh Wooseok, Manager at Chesley Investment Advisory, provides a chart-focused market analysis using Bollinger Bands and moving averages. He argues that the KOSPI sell-off was not fundamental-driven and advises against selling into the bounce. He warns that Samsung Electronics and SK Hynix have experienced a bearish weekly Bollinger mid-band breakdown that often leads to the lower band, and similarly advises selling GigaVis. He flags Amorepacific and Samsung Electro-Mechanics as setups to watch if earnings materialize, while noting Hybe remains in a downtrend to avoid.

  • KOSPI bounce should not be sold because the decline lacked fundamental triggers
  • Samsung Electronics and SK Hynix broke weekly Bollinger mid-band, signaling further downside
  • GigaVis also broke its mid-band and is recommended as a sell from a chart perspective
  • Amorepacific may enter an uptrend if Q2 earnings confirm strong cosmetics data
  • Hybe stays in a downtrend and is unattractive until a base pattern emerges
  • Samsung Electro-Mechanics is watched for a potential breakout once earnings validate high valuation

KOSPI decline not fundamental, avoid selling.
The KOSPI decline was driven by sentiment, not fundamental deterioration; index found support near 6,448 and reclaimed the 5-day moving average. Selling into this bounce should be avoided because the underlying issues are not fundamental, and the market may stabilize.

Bearish weekly Bollinger break targets lower band.
On the weekly chart, both Samsung Electronics and SK Hynix broke the Bollinger Band mid-band in the first week of July without a strong recovery the following week. Historically, this pattern leads to a move down to the lower Bollinger band, indicating further short-term downside.

Sell GigaVis after mid-band break.
GigaVis has broken below its Bollinger mid-band on the weekly chart. From a trend perspective, the stock could fall further in the short term, so selling is warranted purely on the chart pattern.

Watch Amorepacific for uptrend on earnings.
Amorepacific has been rallying on strong cosmetics export data and earnings. The Bollinger Bands are now narrowing, and if Q2 earnings meet expectations, the stock could enter a sustainable uptrend, making it a setup to watch for a breakout.

Hybe downtrend intact, avoid for now.
Hybe is still in a downtrend and has not broken above it. The Bollinger Bands show compression and additional declines, without yet showing a base-building pattern. As long as the downtrend channel holds, the stock is unattractive.

Watch Samsung Electro-Mechanics for earnings validation.
Samsung Electro-Mechanics is not yet in an earnings explosion phase, but if earnings prove the stretched valuation, the stock could break out of a tightening Bollinger Band pattern and resume an upward trend. This is a watch-for-improvement setup.
