AI summary
IBRX rose 9.9% to $9.29 on Tuesday on 2.19 times its average volume, with the close in the top fifth of the day's range. The note views this as the key event, as no company news was found to explain the move, leaving the price action itself as the primary fact.
Historical data shows a wide five-session range of -16.1 / +1.0 / +17.7 based on 300 similar cases. The strongest alternative reading is that Tuesday could still be the important session if Wednesday holds the gain. The immediate checkpoint is Wednesday's regular session close.

The band is the prior close's neighborhood — what followed similar states as of the cutoff.
4. Same state, or a new one
An issuer release, once found, that ties Tuesday's move to a contract, a trial result, or a dollar figure would replace this reading.
Session 1 is the September 23 close. Five and ten sessions are counted from Tuesday. The gap in this note is the missing issuer explanation.
Tuesday's close was $9.29, up 9.9% from Monday's $8.45. Volume was 2.19 times the 20-day average, and the close sat in the top fifth of the day's range. The stock is 25.3% under its 52-week high. That session is the needle. A search of issuer news for September 22 and 23 did not turn up a release that explains it.
The last operating figure tied to the company in the sources at hand is older than this move. Without a new filing, Tuesday's price is the fact and the reason is not in a company document we could open. Attention on the name is not a catalyst.
The 5-session excess band on Tuesday's state is wide: -16.1 / +1.0 / +17.7 across 300 analogs. A 9.9% day can sit inside a band that wide. It can also be the start of a different tape. Wednesday's regular close is the first check. It is not in yet. Until it is, the note does not treat Tuesday as a new business state.
Other reading, tape, and sources
The other reading
A 9.9% close on twice the usual volume, finishing near the high of the day, can be the session that matters even when the press release is missing. If Wednesday holds the gain on ordinary volume, Tuesday becomes the needle anyway.
What would change this
An issuer release, once found, that ties Tuesday's move to a contract, a trial result, or a dollar figure would replace this reading. A Wednesday close outside the 5-session band would too.
The tape
Tuesday closed at $9.29, up 9.9%, on 2.19 times average volume, with the close in the top fifth of the range. The stock is 25.3% under its 52-week high.
What was filed
No ImmunityBio release dated September 22 or September 23 was found in the issuer items checked for this note. The move is the completed Tuesday session. Wednesday's session is still open and is not described here as a result.
The numbers around the move
Tuesday's state still has a wide 5-session excess band, -16.1 / +1.0 / +17.7. The middle of that band is +1.0%. A single 9.9% session does not by itself replace it. Wednesday's close is the test.
What the stock did
Same state until Wednesday's close leaves the band. No new filing was found that would make Tuesday a company event rather than a price event.
The comparison
Five-session excess -16.1 / +1.0 / +17.7 across 300 analogs on the 1-hour scale. One session -6.9 / +0.2 / +8.0. Ten sessions -17.5 / +0.8 / +28.7. These are historical ranges, not a forecast, and they imply no side.
Sources
Tape and analog band from the September 22 state packet. No September 22 or 23 issuer release was found in the news checks opened for this note. That absence is a coverage limit, not proof that no release exists.
