Great things are happening to the stocks in this article. They’re all outperforming the market over the last month because of positive catalysts such as a new product line, constructive news flow, or even a loyal Reddit fanbase.
While momentum can be a leading indicator, it has burned many investors as it doesn’t always correlate with long-term success. On that note, here is one stock with the fundamentals to back up its performance and two that may correct.
Two Momentum Stocks to Sell:
Trex (TREX)
One-Month Return: +19.5%
Addressing the demand for aesthetically-pleasing and unique outdoor living spaces, Trex Company (NYSE: TREX) makes wood-alternative decking, railing, and patio furniture.
Why Do We Steer Clear of TREX?
- Sales tumbled by 2.1% annually over the last two years, showing market trends are working against it during this cycle
- Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 8 percentage points
- Diminishing returns on capital suggest its earlier profit pools are drying up
Trex’s stock price of $48.49 implies a valuation ratio of 29x forward P/E. Read our free research report to see why you should think twice about including TREX in your portfolio.
Collegium Pharmaceutical (COLL)
One-Month Return: +23.8%
Pioneering abuse-deterrent technology in a field plagued by addiction concerns, Collegium Pharmaceutical (NASDAQ: COLL) develops and markets specialty medications for treating moderate to severe pain, including abuse-deterrent opioid formulations.
Why Does COLL Give Us Pause?
- Smaller revenue base of $796.3 million means it hasn’t achieved the economies of scale that some industry juggernauts enjoy
- Expenses have increased as a percentage of revenue over the last two years as its adjusted operating margin fell by 6.4 percentage points
- Returns on capital haven’t budged, indicating management couldn’t drive additional value creation
At $38.47 per share, Collegium Pharmaceutical trades at 4.6x forward P/E. To fully understand why you should be careful with COLL, check out our full research report (it’s free).
One Momentum Stock to Buy:
Alignment Healthcare (ALHC)
One-Month Return: +66.7%
Founded in 2013 with a mission to transform healthcare for seniors, Alignment Healthcare (NASDAQ: ALHC) provides Medicare Advantage health plans for seniors with features like concierge services, transportation benefits, and technology-driven care coordination.
Why Will ALHC Beat the Market?
- Impressive 45.4% annual revenue growth over the last two years indicates it’s winning market share this cycle
- Earnings growth has trumped its peers over the last four years as its EPS has compounded at 28.5% annually
- Free cash flow margin increased by 11 percentage points over the last five years, giving the company more capital to invest or return to shareholders
Alignment Healthcare is trading at $23.75 per share, or 27.6x forward EV-to-EBITDA. Is now the right time to buy? See for yourself in our in-depth research report, it’s free.
