Gilead (GILD): Big base breakout

We have some interest in Gilead Sciences (GILD).

GILD is breaking out from a massive basing pattern spanning from mid 2015 into late 2025/early 2026. Holding the 129 to 116 zone (61.8% extension of the mid 2024-early 2025 rally projected from the April 2025 low and the big base breakout/retest zone) would maintain this bullish breakout with upside potential to 151 (100% extension) and then toward 187-190 (161.8% extension and big base pattern target).

Rising 13-, 26-, and 40-week moving averages from 125 down to 116 reinforce bullish breakout and retest support on GILD.
