NBIX Director Norwalk sells $228K stake -34% reduction near 90d high
22d ago

Director Leslie Norwalk sold $228K of NBIX shares at $182.01, reducing their direct holdings by 34% near the stock's 90-day high. This continues a pattern of routine selling by this director with no offsetting insider buying, though it occurs amid a Strong Buy analyst consensus.

Where it could go — Our 1-4 conviction sell signals historically beat SPY 55% of the time at 30d; analyst mean target implies upside if stock holds above $165 support.

NBIX CLO Lippoldt exercise-and-sell $1.8M — 10K newly exercised options near 90d high
39d ago

NBIX Chief Legal Officer Darin Lippoldt sold 10,000 newly exercised option shares at $179.60 for $1.8M on July 9, just 0.8% below the 90-day high of $181.00; his pre-existing stake is unchanged. This is the 19th sell on record for Lippoldt and follows a near-identical $1.7M exercise-and-sell just 10 days prior on June 29, fitting a clear pattern of mechanical compensation monetization rather than a directional view on NBIX. Bull case: STRONG BUY consensus from 32 of 37 analysts and earnings on July 30 with $1.59 EPS consensus could sustain the stock above $175; bear case: a miss on July 30 earnings breaks the $155 30-day low support.

Where it could go — Our conviction 1-4 officer sell signals: 59% beat SPY at 30d (n=3,060, avg +3.2% vs SPY); bull holds $175, bear breaks $155.

NBIX Chief Regulatory Officer exercises options, sells $791K near 90-day high
39d ago

Chief Regulatory Officer Ingrid Delaet exercised options and sold 4,367 shares for $791K at $181.02, just 0.1% below the 90-day high. This appears to be a mechanical transaction following her established pattern of option exercises rather than a reduction of her core position.

Where it could go — Our 1-4 conviction officer sells: 59% beat SPY at 30d with +3.2% average outperformance; watch $181.18 as resistance.

NBIX Chief Regulatory Officer exercises options, sells $2.6M near 90-day high
42d ago

Chief Regulatory Officer Ingrid Delaet exercised options and sold 14,571 shares for $2.6M at $178.65, just 1.3% below NBIX's 90-day high. This transaction is mechanical—newly exercised options sold via likely pre-planned arrangement—and does not reduce her existing stake, signaling no bearish intent. Bull case requires holding $155 support; bear breaks $178.65 resistance.

Where it could go — Our 1-4 conviction officer sells: 59% beat SPY at 30d; bull holds $155, bear breaks $178.65.

NBIX CLO exercises options, sells $1.7M near 90-day high
52d ago

Chief Legal Officer Lippoldt Darin exercised options and sold 10,000 shares at $170.15 for $1.7M, representing newly acquired shares rather than a reduction in existing holdings. This transaction appears mechanical given its exercise-and-sell nature, proximity to the 90-day high of $171.43, and the insider's history of 18 similar option-related sales. Broad historical patterns show 41.7% of similar signals lead to positive 90-day returns, but this specific trade offers minimal directional insight.

Where it could go — 41.7% positive at 90d; bull holds $154, bear breaks $170.

Conviction 2/10LOW importance20% confidence
NEUTRAL30d +5.1% vs SPY
NBIX Director exercises options, sells $4.1M via 10b5-1 — 15.9K shares remain
72d ago

Stephen A. Sherwin exercised 25,000 options at $64.10 and sold the shares at $165.32 (value: $4.1M). Sherwin retains 15,860 direct shares, with no options remaining after this exercise-and-sell transaction.

Where it could go — Exercise-and-sell transactions are routine option-exercise mechanics with minimal directional signal; the insider's pre-existing equity stake was unchanged.

NBIX Director Norwalk sells $210K stake -31% reduction near 90d highs
73d ago

Director Leslie Norwalk sold $210K of NBIX at $168.06, reducing their stake by 31% while the stock traded just 0.9% below its 90-day high. This continues a multi-year pattern of director selling near peak prices with no insider buying activity to offset the bearish signal.

Where it could go — Analyst mean target implies upside from current levels; bear case if stock breaks below $125 support.

NBIX Officer exercises 24,965 options, sells $2.2M — newly exercised shares only
77d ago

Cooke Julie exercised 24,965 options at $81.49 and sold the resulting shares at $154.83 ($2.2M). The sale came from newly exercised options and did not reduce previously held shares, leaving 45,097 directly held shares.

Where it could go — Exercise-and-sell transactions are largely mechanical and carry limited directional signal.

Where it could go — Exercise-and-sell transactions carry minimal directional signal; the insider's position was not reduced, only newly exercised options were sold.

84d ago

Chief Corporate Affairs Officer David Boyer sold $609K worth of NBIX at $156.64, reducing his stake by 33% while the stock traded just 3.5% below its 90-day high. This first-time sale follows three recent director sales and occurs despite strong analyst consensus, suggesting potential internal concerns about valuation.

Where it could go — Analyst mean target unavailable; bear case if stock breaks below $125 support level.

NBIX insider sells $37.8M; 205K of 245K shares from same-day exercise
91d ago

Gorman Kevin Charles sold 245,088 shares at ~$154.33 ($37.8M); 205,088 of them came from a same-day option exercise at $43.24. The remaining 40,000 shares came from existing holdings, leaving 511,293 directly held shares.

Where it could go — Partial reduction of existing holdings. While the bulk came from option exercise, the 40,000-share trim from direct holdings represents a meaningful reduction of existing positions.

94d ago

99d ago

Director Norwalk sold $591K worth of NBIX shares, reducing her stake by 61% while the stock traded just 0.8% below its 90-day high. This isolated sale near peak prices suggests profit-taking rather than fundamental concern, but the lack of supporting buyer activity limits its bearish significance.
