3 Russell 2000 Stocks We’re Skeptical Of

PUBM Cover Image

The Russell 2000 (^RUT) is home to many small-cap stocks, offering investors the chance to uncover hidden gems before the broader market catches on. However, these companies often come with higher volatility and risk, as their smaller size makes them more vulnerable to economic downturns.

Picking the right small caps isn’t easy, and that’s exactly why StockStory exists - to help you focus on the best opportunities. That said, here are three Russell 2000 stocks to avoid and better alternatives to consider.

PubMatic (PUBM)

Market Cap: $387.8 million

Powering billions of daily ad impressions across the open internet, PubMatic (NASDAQ: PUBM) operates a technology platform that helps publishers maximize revenue from their digital advertising inventory while giving advertisers more control and transparency.

Why Do We Avoid PUBM?

  1. Competitive market dynamics make it difficult to retain customers, leading to a weak 96% net revenue retention rate
  2. Extended payback periods on sales investments suggest the company’s platform isn’t resonating enough to drive efficient sales conversions
  3. Efficiency has decreased over the last year as its operating margin fell by 7.4 percentage points

PubMatic’s stock price of $8.23 implies a valuation ratio of 1.4x forward price-to-sales. Dive into our free research report to see why there are better opportunities than PUBM.

Luxfer (LXFR)

Market Cap: $324.5 million

With its magnesium alloys used in the construction of the famous Spirit of St. Louis aircraft, Luxfer (NYSE: LXFR) offers specialized materials, components, and gas containment devices to various industries.

Why Should You Sell LXFR?

  1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 2.6% annually over the last two years
  2. Sales are expected to decline once again over the next 12 months as it continues working through a challenging demand environment
  3. Earnings growth over the last five years fell short of the peer group average as its EPS only increased by 2.3% annually

At $12.18 per share, Luxfer trades at 10.9x forward P/E. If you’re considering LXFR for your portfolio, see our FREE research report to learn more.

Ridgepost Capital (RPC)

Market Cap: $795 million

Operating as a bridge between institutional investors and hard-to-access private market opportunities, Ridgepost Capital (NYSE: RPC) is an alternative asset management firm that provides access to private equity, venture capital, impact investing, and private credit opportunities in the middle and lower middle markets.

Why Are We Wary of RPC?

  1. Performance over the past two years shows its incremental sales were less profitable, as its 5.5% annual earnings per share growth trailed its revenue gains
  2. ROE of 4.1% reflects management’s challenges in identifying attractive investment opportunities

Ridgepost Capital is trading at $7.26 per share, or 7.3x forward P/E. Read our free research report to see why you should think twice about including RPC in your portfolio.
