Durect Skyrockets 244.67%—What’s Fueling This Record Surge?

Summary
• Bausch Health’s $1.75/share all-cash acquisition of Durect announced July 29
• DRRX surges from $0.5527 previous close to $1.905 intraday high
• 52-week high of $2.64 reached as takeover premium drives frenzy

Durect (DRRX) has unleashed a volcanic 244.67% rally on news of a transformative $63M upfront acquisition by Bausch Health. The stock traded as high as $2.64—matching its 52-week peak—amid a 175.85% surge in turnover. With larsucosterol’s FDA Breakthrough Therapy Designation for alcoholic hepatitis fueling optimism, investors are scrambling to decode whether this is a once-in-a-lifetime windfall or a cautionary bid.

Bausch Health's $1.75/Share Acquisition Ignites Market Optimism
Durect’s meteoric rise stems from Bausch Health’s $1.75/share all-cash takeover offer, a 217% premium over its July 28 close. The deal includes $63M upfront and potential $350M in milestone payments if larsucosterol achieves $500M and $1B annual sales. With larsucosterol in Phase 3 trials for alcoholic hepatitis—a $1.2B unmet need—investors are pricing in accelerated commercialization potential. The $1.75 floor price created a floor for speculation, while the CVR contingent rights added a speculative premium as traders bet on milestone payouts.

Biotech Sector Mixed as DRRX Outperforms
While DRRX’s 244.67% rally dwarfs peers, the broader biotech sector remains volatile. Amgen (AMGN) edged up 0.54%, reflecting modest momentum in large-cap pharma. However, Sanofi’s $1.6B Vicebio acquisition and Roche’s COPD trial failure highlight sector fragmentation. DRRX’s surge is idiosyncratic, driven by the unique acquisition structure and larsucosterol’s unmet-need profile, which diverges from sector-wide trends.

Options Playbook: Leveraging High-Leverage Calls for Aggressive Bulls
• RSI: 39.93 (oversold)
• MACD: -0.0155 (bearish), Signal Line: -0.0133 (bearish), Histogram: -0.0023 (bearish)
• 200D MA: $0.8217 (above price)
• Bollinger Bands: $0.5006–$0.6906 (price at $1.905, well above)

Technical indicators signal a short-term overbought condition, but the acquisition premium has created a bullish anomaly. Key levels: $1.86 (intraday low) as support; $2.64 (52-week high) as resistance. With 100-day MA at $0.6658, the move is structurally detached from historical trends. ETFs like XLK (XLF) could mirror biotech sector breadth, but DRRX’s volatility makes options more compelling.

RRX at Inflection Point: Break $2.64 for New Milestone
Durect’s 244.67% surge is a liquidity-driven sprint toward the $2.64 52-week high, but sustainability hinges on Bausch Health’s ability to secure shareholder approval. The $1.75 floor price provides a bid, but the CVR contingent rights add a speculative layer. Watch for $2.64 breakout to validate momentum, with Amgen (AMGN, +0.54%) as a sector benchmark. If the 52-week high holds, options like DRRX20250815C2 could multiply gains. Conversely, a pullback below $1.86 intraday low would trigger short-term profit-taking. Action: Target $2.64 breakout or $1.86 support—either way, volatility is priced in.
