Robert Shiller on Samsung Electronics
Samsung's own record beat estimates on the day the sector was still selling it off, and the reversal two days later carried no new information about Samsung at all.
Shiller’s test for a narrative-driven move is whether the price change and the news that supposedly caused it actually line up in time (Irrational Exuberance). Samsung’s four trading days from July 28 to July 31, 2026, put that test unusually cleanly, because the company’s own results landed in the exact middle of the swing rather than at either end of it.
The selloff came first, and it wasn’t about Samsung. On July 28, South Korea’s KOSPI fell more than 11% on “deepening AI fatigue” and worries over China’s chipmaking progress, dragging Samsung and SK Hynix down together — the story was sector-wide and macro, not company-specific (texxr.com/1173805). The next day, SK Hynix reported second-quarter revenue up 257% and operating profit up 557%, both below Wall Street’s estimates, and the market kept selling (texxr.com/1173885) — a different company’s earnings, still moving Samsung’s stock.
Samsung’s own results arrived July 30, squarely inside the selloff: revenue up 130% year over year to roughly $118.1 billion, operating profit up 1,814% to about $61.46 billion, both credited to AI memory demand. The Financial Times reported investors were still dumping chip stocks that same day — Samsung’s own beat did not stop the story that had nothing to do with it (texxr.com/1173988). Then, with no comparable new information about either company, Samsung and SK Hynix shares surged more than 20% in Seoul on July 31, a reversal the record calls sharp (texxr.com/1174063) — the same fear that drove the selloff simply stopped being the story.
Shiller’s mechanism is a narrative that recruits its own evidence and then loses its grip on it, and this is closer to the second half than the first: no new fact reversed between the 11% fall and the 20% rally, only which name — SK Hynix’s miss, or the AI-fatigue story attached to it — the market was reading Samsung through that week. Samsung’s own numbers, the one fact that stayed constant across all four sessions, moved the price least.
