BitMine Immersion Technologies (BMNR) stock surged 12% on March 31, closing at $19.78, following a bullish price target upgrade from B. Riley and a significant expansion of its Ethereum holdings. The investment firm raised its target for BMNR to $33 from $30, maintaining a Buy rating, citing the launch of MAVAN, BitMine's institutional-grade Ethereum staking platform.
The rally was primarily driven by a short squeeze rather than fresh institutional buying. Analysis of the put-call ratio shows that on March 27, the volume ratio spiked to 1.04, indicating aggressive bearish positioning. By March 31, this ratio collapsed to 0.52 while open interest remained flat at 0.47, signaling that existing bearish bets were being closed, forcing the price higher.
Fundamentally, BitMine bolstered its position by adding 71,179 ETH last week, its largest weekly purchase of 2026. This marks a five-week buying streak, bringing the company's total holdings to 4.73 million ETH, which represents 3.92% of Ethereum's circulating supply. The firm's total crypto and cash treasury now stands at $10.7 billion, with approximately $177 million in annualized staking revenue from its 3.14 million staked ETH (worth ~$6.3 billion). B. Riley noted that about 67% of holdings are already staked, with potential annualized rewards of roughly $285 million at full deployment.
Despite the positive catalysts, technical hurdles remain. The stock is pressing against the upper trendline of a descending channel that has contained its price since early December, with failed breakout attempts in early January and mid-March. The Chaikin Money Flow (CMF) indicator remains below zero, suggesting a lack of sustained institutional buying pressure behind the rally. A bullish divergence on the Relative Strength Index (RSI) between November 21 and March 30 hints at weakening selling momentum.
A daily close above $21.22 is needed to confirm a definitive channel breakout. This level aligns with the 0.5 Fibonacci retracement. A successful breakout could open a path toward $24.56 and $28.69. Conversely, failure to hold $19.46 could signal exhaustion, with a close below $17.88 reopening the lower channel and risking a test of the $17.12 support level. The stock's near-term trajectory is closely tied to Ethereum's performance, which was up 3.6% over the past 24 hours, providing a direct tailwind to BitMine's treasury valuation and revenue outlook.
