How INHIBRX BIOSCIENCES INC looks technically

INHIBRX BIOSCIENCES INC (INBX) is trading 19.7% above its 200-day average, the long-term trend line — a longer-term uptrend. Its 50-day average crossed above its 200-day average about 274 trading days ago — a "golden cross", a bullish long-term signal. There is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 14, below the 25 that marks a real trend), though buyers have been pushing harder than sellers lately — pressure, not a trend. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 63, neither overbought (above 70) nor oversold (below 30). It just made a new 20-day high, its first since 2026-07-09, pushing above its recent trading range. It is 33.3% below its highest point of the past year.

Position in its 14-day rangeit is trading near the top of its 14-day range ($80.42 to $105.65) — its "stochastic" reading is 92 out of 100, where 0 would mean closing exactly at the 14-session low and 100 exactly at the high. This measures WHERE the price sits inside its recent range, which is a different question from the RSI beside it: RSI is a momentum gauge, measuring how FAST the price has been moving, so a stock can drift quietly to the bottom of its range with an ordinary RSI, or fall sharply and still sit in the middle. It has been climbing within that range over the last few sessions.92.0

Volatility

Band width vs its own 6 monthsday-to-day price swings are about average versus its own recent 6-month history68th percentile
Typical daily rangein a typical session it travels about $6.29 between its high and its low — about 6.1% of its price. That is its "average true range" over the last 14 sessions, which also counts the distance from the previous close, so a day that opens well away from yesterday counts as the large move it was$6.29
Bollinger bands (20-day, ±2σ)most of its recent trading has stayed between about $74.93 and $104.36 — the "Bollinger bands", a range drawn two standard deviations either side of its 20-day average price, which widens when the stock gets more volatile and narrows when it settles$74.93 – $89.64 – $104.36
Typical daily range (% of price)its price moves about 6.1% in a typical session — more volatile than most companies we cover. This is the average gap between a session's high and low over the last 14 sessions, counting overnight moves, expressed against the current price so it can be compared with companies trading at any price6.1%
Stretch from the 200-day averageit is trading 2.7 daily ranges above its 200-day average price (19.7% above it in plain percentage terms) — a way of asking how far it has stretched from its own average in units of how far it normally moves in a day, so a calm company and a jumpy one can be compared on the same scale2.7 daily ranges above its 200-day average

Vs the Ichimoku cloudtrading inside the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-07-16 and projected forward over today's price, the zone traders read as unresolved — neither side has established a trend, and the band is where that gets settled.

Wave structure

No Elliott-wave labelling currently fits its swings: the recent highs and lows do not satisfy the three rules a five-wave count has to obey, so there is no count to show rather than a count we are unsure about.

Change over time is not available yet: it needs two readings of the same reporting period at least 30 days apart, and we have been recording these estimates since 2026-08-04. An estimate for a DIFFERENT quarter is not a revision, so a reading from before the last report is never compared with one after it.

The consensus estimate for the next reporting period, and how it has moved between readings of that SAME period. A change is measured only between readings estimating one period — when a company reports, the consensus moves to the next quarter and the two numbers are not comparable.

Reported to FINRA as of the 2026-07-31 settlement date. Short interest is reported to FINRA and published on a delayed, bi-monthly schedule (as of a settlement date, disseminated roughly eight business days later) — it is NOT real-time, does not cover every venue or all US trading, and is not a short-squeeze prediction or investment advice. Days-to-cover is the value FINRA reports; percent of float is not shown because the source file carries no share-count denominator — where a percent appears it is of shares OUTSTANDING, the larger base, and is therefore a floor on percent of float.
