Buy, Sell, Or Hold Alnylam Stock At $280?
ALNY Stock
Trefis
Alnylam Pharmaceuticals (NASDAQ:ALNY), a biotech company specializing in RNA interference therapeutics for genetically defined diseases, has experienced remarkable growth with its stock price surging from below $150 in March 2024 to over $280 currently, representing nearly a 100% increase.
Trefis
This impressive performance was largely driven by promising clinical trial results for its cardiovascular drug Amvuttra released in mid-2024. Today marks another significant milestone as the FDA has expanded Amvuttra's approval to include a broader patient population with a genetic heart condition, building upon its existing approval for treating protein accumulation in nerves. [1]
The expanded approval carries substantial revenue implications, with Amvuttra now projected to reach approximately $8 billion in peak sales—a dramatic increase considering Alnylam's total revenue was just $2 billion last year. In response to this development, the company's stock jumped more than 10% during trading on Friday, March 21.
Now that the stock has seen a large move, it looks relatively expensive - making it a expensive pick to buy at its current price of around $280. We believe there are some minor concerns with ALNY stock, which makes it relatively expensive given that its current valuation looks extremely high.
We arrive at our conclusion by comparing the current valuation of ALNY stock with its operating performance over the recent years as well as its current and historical financial condition. Our analysis of Alnylam Pharmaceuticals along key parameters of Growth, Profitability, Financial Stability, and Downturn Resilience shows that the company has a strong operating performance and financial condition, as detailed below. That said, if you seek upside with lower volatility than individual stocks, the Trefis High-Quality portfolio presents an alternative - having outperformed the S&P 500 and generated returns exceeding 91% since its inception.
Going by what you pay per dollar of sales or profit, ALNY stock looks very expensive compared to the broader market.
• Alnylam Pharmaceuticals has a price-to-sales (P/S) ratio of 16 vs. a figure of 3.2 for the S&P 500

• Its revenues have grown 23.0% from $1.8 Bil to $2.2 Bil in the last 12 months (vs. growth of 5.2% for S&P 500)

In summary, Alnylam Pharmaceuticals' performance across the parameters detailed above are as follows:
• Growth: Extremely Strong
• Profitability: Extremely Weak
• Financial Stability: Extremely Strong
• Downturn Resilience: Neutral
• Overall: Strong
Despite Alnylam's current elevated valuation making the stock appear costly, which supports the assessment that ALNY represents an expensive investment opportunity, potential investors should consider the company's shifting trajectory.
After years focused primarily on drug development, Alnylam is now entering a phase where it can capitalize on these efforts. While the current valuation might seem steep at first glance, projected sales growth averaging approximately 25% annually over the next three years, coupled with potentially much stronger earnings growth, suggests the premium may be justified by the company's improving financial outlook.
Worried about the rich valuation of ALNY stock? As an alternative, consider the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to produce strong returns for investors. Why is that? The quarterly rebalanced mix of large-, mid- and small-cap RV Portfolio stocks provided a responsive way to make the most of upbeat market conditions while limiting losses when markets head south, as detailed in RV Portfolio performance metrics.

Why Digital Turbine Stock Plummeted Today
Digital Turbine stock saw a massive post-earnings rally on Tuesday, but its share price slipped as the week progressed. Investors took profits on the stock today, and geopolitical risk factors also worked to push its share price lower. Digital Turbine is guiding for strong adjusted EBITDA growth this year, but geopolitical dynamics could create valuation volatility. 10 stocks we like better than Digital Turbine › Digital Turbine (NASDAQ: APPS) stock saw a round of substantial sell-offs Friday. The adtech specialist's share price closed out the daily session down 14.6% amid a 0.3% decline for the S&P 500 index and a 0.6% decline for the Nasdaq Composite index. Following an explosive post-earnings rally for the stock earlier this week, investors sold shares and moved to take profits. In addition to profit-taking action, Digital Turbine stock moved lower due to new restrictions on technology exports and fears that the conflict between Israel and Iran could continue to escalate. Digital Turbine stock had actually been up as much as 1.8% in today's trading, but action on the stock turned bearish as investors reacted to risk factors and took profits on gains posted earlier in the week. The company's share price skyrocketed in Tuesday's trading after it posted better-than-expected quarterly results and forward guidance, but its share price has moved lower in subsequent trading. In addition to profit-taking activities, Digital Turbine stock was pressured by geopolitical dynamics today. The Wall Street Journal published a report today stating that the Trump administration wants to further strengthen export restrictions and prevent companies including Samsung, Taiwan Semiconductor Manufacturing, and SK Hynix from shipping chipmaking technologies to their factories in China. Adding another bearish catalyst, investors moved out of stocks due to the possibility that military strikes between Israel and Iran will intensify and that the U.S. could enter the conflict on behalf of Israel. For the current fiscal year, Digital Turbine is guiding for revenue between $515 million and $525 million -- good for annual growth of roughly 6% at the midpoint of the target range. Meanwhile, non-GAAP (adjusted) earnings before interest, taxes, depreciation, and amortization (EBITDA) are projected to be between $85 million and $90 million -- representing growth of 21% at the midpoint of the guidance range. Digital Turbine's performance outlook became significantly stronger following its quarterly release earlier this week, but there are factors that could cause continued volatility for the stock. The company does most of its business in China, and rising geopolitical tensions present substantial risk factors even though it's not a hardware company.
