    "South Korea’s customs data showed exports in the first 20 days of October rose 105.4% from a year earlier. [E1]",
    "The working-day-adjusted daily export value was $4.74 billion, up 65.9% from the same period last year. [E2]",
    "Semiconductor exports rose 222.5% to $27.5 billion. [E3] MarketScreener reported that chips accounted for 44.7% of exports. [E4]",
    "The September final release recorded $121.1bn in exports, up 83.7%, with semiconductor exports up 260.3%, petroleum products up 73.3% and ships up 31.4%; cars, wireless equipment and appliances fell. [E5] Korea Customs Service issued that final September release on Oct. 15. [E6] This moves the paper’s Oct. 13 focus from a Korean chip-share sell-off to the country’s export figures.",
    "**The desk's reading.** The September release is the prior: semiconductor growth exceeded the other product rates it reported. The early October figures point the same way, so the desk puts a 65% probability on the full-month release showing semiconductor export growth above every other published product growth rate. The strongest competing reading is that another product category’s growth rate matches or exceeds chips once the month is complete.",
    "**The next test.** The forecast settles YES if Korea Customs Service posts a full October release by Nov. 16 and its semiconductor export growth rate exceeds every other published product growth rate. It settles NO if any other published product rate ties or exceeds semiconductors, if the release omits a comparable product rate, or if no full-month release appears by Nov. 16."
