Moving with its memory & storage peers
- SKHY −4.35% on the last session vs SPY −0.42%: −3.9 pts of stock-specific move.
- News: Memory and storage peers fell broadly; Seoul memory stocks declined and US session saw sector-wide weakness with no specific SKHY news.
- Memory & storage basket -3.7% (-3.3 pts vs SPY; SNDK -4.9%, MU -4.8%, STX -4.1%, WDC -3.0%): the stock moved with its peers. Overnight: SK Hynix (Seoul) -2.4%, Samsung (Seoul) -2.4%.
- Aftermath, theme selloff (Memory & storage peers -3.3 pts vs SPY; the stock -4.3%): After its 6 theme selloffs in the past 5 years, SKHY typically lost 0.3% over the next day (median) and was higher only 33% of the time; half the outcomes fell between -3.1% and +0.2%. An ordinary day: -0.1%. Among S&P 500 stocks after theme selloffs, that ranks #43 of 81. (Low confidence: few independent periods.)

Median gain from the close of the session the event was known, over each holding period; Reaction day (earnings only): the session that first traded on the report, from the close before it; #rank among the S&P 500 stocks after the same kind of event (#1 = best). "Big" is SKHY's own: its worst / best 10% of days over the prior 2 years. Highlighted: happening in the latest session or today, from the live quote.
Insider unplanned sale
An insider's sale outside a pre-arranged 10b5-1 plan; entry the session after its SEC filing.
| Holding | Events | Median (likely range) | Confidence | Rank | Up | vs SPY | Range of outcomes (worst · 25–75% · median · best) | vs S&P 500 stocks (their medians) |

Range of outcomes: all of SKHY's unplanned insider sales in the past 5 years, from the worst to the best result over each holding period; the box holds the middle half, the tick is the median. A wide box means the median alone says little. Hover the median for the average.
Insider unplanned sale by trend
| When it happened | Events | 1 day | 1 week | 1 month | 1 quarter |
|---|---|---|---|---|---|

The same event split by where SKHY stood against its 200-, 50- and 20-day averages when it happened (a dip in an uptrend vs a falling knife); "vs" is the plain any-day median in that trend; "now" marks where it stands today. Splitting halves the evidence, so watch the confidence letters: H / M / L.
Latest unplanned insider sales
Aftermath: entry is the close of the first session the event was fully known (the same session for price moves, the reaction session for earnings, the next session for Reddit, analyst and insider events, which are dated by day). Repeats within a few sessions count as one event. Past performance after an event says nothing certain about the next one. Not advice.
