NOTE TRAI Daily Overview narration. Screening/research, not investment advice.

1
00:00:00.350 --> 00:00:05.452
TRAI daily overview for October 22. Screening and research, not investment
advice.

2
00:00:05.652 --> 00:00:12.432
SPY fell 1.2%, QQQ 2.9% and the chip ETF SMH 6.0%.

3
00:00:12.832 --> 00:00:19.544
The VIX, the market's 30-day implied volatility, rose 2.4 points to 19.0,
a transitional reading.

4
00:00:19.744 --> 00:00:25.364
SPY's realized volatility, how much it actually moved over 20 days, is
only 9.8%;

5
00:00:25.364 --> 00:00:28.833
that 9.2-point gap is the volatility risk premium.

6
00:00:29.033 --> 00:00:33.923
The term structure, short-dated versus 3-month VIX, is in mild contango,
which is normal.

7
00:00:34.123 --> 00:00:37.892
TRAI's regime score is +17.5: neutral and choppy.

8
00:00:38.292 --> 00:00:50.785
Earnings drove big moves: LRCX fell 11.8%, SPOT rose 11.1% and META fell
7.0% after missing EPS estimates by 30%.

9
00:00:50.985 --> 00:00:57.078
MRNA fell 17.6% with no earnings in the data, so the cause is unknown
here.

10
00:00:57.478 --> 00:01:01.766
Long momentum means a market-beating rise on heavy volume, closing above
VWAP,

11
00:01:01.766 --> 00:01:03.965
the day's volume-weighted average price.

12
00:01:04.165 --> 00:01:10.339
BX led with a residual z-score of 6.2, a market-adjusted move about 6
times its normal noise.

13
00:01:10.739 --> 00:01:14.788
Short momentum had 12 names, half of them chips, led by GEV.

14
00:01:14.988 --> 00:01:20.598
Mean reversion, big moves on ordinary volume that may fade, flagged 17,
led by FCX.

15
00:01:20.998 --> 00:01:28.271
Over 126 replayed sessions, short momentum's expectancy, the average net
profit per trade,

16
00:01:28.271 --> 00:01:33.442
is -0.46%, with a t-stat of -3.7: beyond ±2, so likely not luck.

17
00:01:33.642 --> 00:01:35.885
No bucket has a significant positive edge.

18
00:01:36.285 --> 00:01:41.305
Correlation clusters are stocks that move together: the largest, 24 names
led by semis,

19
00:01:41.305 --> 00:01:46.268
has an average correlation of 0.59, so today's 12 shorts are about 3
independent bets.

20
00:01:46.668 --> 00:01:49.740
Gap risk is a jump past your stop overnight, often on earnings.

21
00:01:49.940 --> 00:01:58.487
42 names report within 5 sessions, including picks KLAC, NOW and GOOGL on
October 28.

22
00:01:58.887 --> 00:02:06.361
Over 20 days, staples, utilities and energy lead SPY by 8 to 11 points;
semis and tech trail by 12 and 6.
