Forecast batch: 8/7/26

^KS11's band is still building its audit record. Sigmacast's calibrated band is sized from realized volatility and graded against every terminal close as its audit record builds. Horizon grades appear as each one's history matures — current status is below.

Market-data read

^KS11 reads range-bound — no clean directional character at any horizon (ER 0.26 / 0.07 / 0.25). Recent action is directionless chop rather than a trend. Term-structure band: ±11.2% / ±17.4% / ±26.8% (7/14/28d).

SETUP

The KOSPI (^KS11) is a market index covered by the Sigmanomics analytics platform. The ^KS11 index closed at 6,259.14 on August 7, 2026, reflecting a decline of 0.25% from the previous close of 6,274.68.

WHAT'S DRIVING IT

Over the past 30 days, the index has experienced a strong downtrend with a decline of 25.15%, ranging between 5,262.77 and 8,861.70. The price currently trades below its 20-day moving average of 6,577.56. The 14-day RSI stands at 42.9, in neutral territory, indicating balanced momentum.

THE RISK

Over the same 30-day window, daily-return volatility was 5.75%, reflecting heightened price variability for this index.

WHAT WE'RE WATCHING NEXT

Daily-return volatility of 5.75% runs elevated for this index, so price ranges are likely to stay wide — watch how price behaves around its recent range rather than treating any single level as fixed. ^KS11 is currently trading 4.84% below its 20-day moving average. Its 14-day RSI reads 42.9, currently in neutral territory.
