Summary
- LLKKF is realising 209.9% annualised volatility over the last 21 sessions, the elevated end of its range — higher than 78% of readings over the past 1 year.
- Volatility has risen from 179.6% to 209.9% over the past month (+17% relative), so the near-term trend in risk is against short-volatility positioning.
- The Parkinson range estimate (291.5%) exceeds close-to-close vol (209.9%): the stock travels a wide intraday range but keeps closing near where it opened — mean-reverting chop rather than trend.
- 48% of total variance is delivered overnight (273.5% annualised) against 283.3% during the session — risk is mostly intraday and can be managed inside the session.
- On the empirical distribution, a 1-day 95% VaR is -16.90% with an expected shortfall beyond it of -21.18%. Excess kurtosis of 1.3 and 0.95% of days beyond 3σ (a normal distribution would give 0.27%) mean option-pricing models that assume normality will understate the tail.
- Absolute returns are autocorrelated at lag 1 (0.208 vs a 0.191 significance band), confirming volatility clustering — quiet days follow quiet days, so today’s reading carries information about tomorrow’s.
- Worst peak-to-trough drawdown over the window was -35.1% (trough 2026-07-31), with an Ulcer Index of 16.83 capturing how long it stayed underwater.

Volatility Cone Close-to-Close · 1 year of overlapping windows
Every realized-vol reading the stock has produced at each horizon, as a percentile envelope. The marker is today. A dot riding the top of the cone says vol is stretched for that horizon — which is the comparison that matters, since short windows are naturally noisier than long ones.

* Percentile is based on fewer than 60 overlapping windows at that horizon — not enough independent history to rank against. Widen the cone lookback to firm it up.
Realized Term Structure
Current realized vol at each horizon against the median for that same horizon. When the short end sits above the long end the curve is inverted — the market is pricing a near-term event, and the spread has historically closed by the short end falling rather than the long end rising.
Estimator Comparison
Five estimators of the same quantity. They disagree in informative ways: Parkinson and Garman-Klass read the intraday range and are blind to overnight gaps; Rogers-Satchell is drift-independent, so it does not inflate on a strong trend; Yang-Zhang combines overnight, open-to-close and Rogers-Satchell and is the one to quote against implied vol.

|---|---|---|---|---|---|
| Close-to-Close | 209.9 | 194.8 | 166.5 | 166.5 | total risk, incl. gaps |
| Parkinson | 291.5 | 318.2 | 274.0 | 274.0 | intraday range only |
| Garman-Klass | 304.1 | 313.5 | 271.4 | 271.4 | range + open/close |
| Rogers-Satchell | 335.6 | 326.5 | 285.5 | 285.5 | drift-independent |
| Yang-Zhang | 414.0 | 445.2 | 392.6 | 392.6 | gaps + range + drift |
Conditional Volatility Models
A GARCH(1,1) fit needs at least one year of returns. Widen the date range to enable it.
Tail & Drawdown Risk
VaR and expected shortfall are historical — read straight off the empirical return distribution, with no normality assumption. The parametric figures next to them assume a Gaussian; the difference between the two is the size of the tail your model would have missed.

Volatility Clustering ACF, 105 returns
Autocorrelation of raw returns, absolute returns and squared returns. Raw returns should be near zero (an efficient market); absolute and squared returns should not be — that persistence is the ARCH effect every conditional-vol model exists to capture. Bars outside the ±0.191 band are significant at 95%.

Volatility Change by Month month-over-month % change in 21-day realized vol
Not price returns — this is how much the volatility itself moved each month. Persistent positive months flag a season when risk tends to build in this name.

You ask
“How does NVDA usually trade through earnings?”
It calls
→ ka.earnings_moves(NVDA)
→ ka.options_expected_move(NVDA)
→ ka.options_expected_move(NVDA)
It answers
NVDA has averaged a 9.2% absolute move on the day after earnings and closed higher 67% of the time. Two in three reactions land between −4.2% and +16.3% — the distribution is skewed right, not symmetric.
