3 Stocks Under $10 We Approach with Caution

MQ Cover Image

Stocks trading in the $1-10 range are generally smaller players with less risk than their penny stock counterparts. But that doesn’t mean the underlying businesses are cheap, and we advise caution as many have questionable fundamentals.

The downside that can come from buying these securities is precisely why we started StockStory - to isolate the long-term winners from the losers so you can invest with confidence. That said, here are three stocks under $10 to avoid and some other investments you should consider instead.

Marqeta (MQ)

Share Price: $6.18

Founded by CEO Jason Gardner in 2009, Marqeta (NASDAQ: MQ) is an innovative card issuer that provides companies with the ability to issue and process virtual, physical, and tokenized credit and debit cards.

Why Are We Wary of MQ?

  1. Products and services have few die-hard fans as sales have declined by 4.7% annually over the last three years
  2. Operating profits fell over the last year as its sales dropped and it struggled to adjust its fixed costs
  3. Lacking free cash flow generation means it has few chances to reinvest for growth, repurchase shares, or distribute capital

At $6.18 per share, Marqeta trades at 4.4x forward price-to-sales. Dive into our free research report to see why there are better opportunities than MQ.

Brookdale (BKD)

Share Price: $7.33

With a network of over 650 communities serving approximately 59,000 residents across 41 states, Brookdale Senior Living (NYSE: BKD) operates senior living communities across the United States, offering independent living, assisted living, memory care, and continuing care retirement communities.

Why Do We Think Twice About BKD?

  1. Annual sales declines of 3.8% for the past five years show its products and services struggled to connect with the market during this cycle
  2. ROIC of -0.5% reflects management’s challenges in identifying attractive investment opportunities
  3. 12× net-debt-to-EBITDA ratio makes lenders less willing to extend additional capital, potentially necessitating dilutive equity offerings

Brookdale is trading at $7.33 per share, or 3.8x forward EV-to-EBITDA. If you’re considering BKD for your portfolio, see our FREE research report to learn more.

GoodRx (GDRX)

Share Price: $3.58

Started in 2011 to tackle the problem of high prescription drug costs in America, GoodRx (NASDAQ: GDRX) operates a digital platform that helps consumers find lower prices on prescription medications through price comparison tools and discount codes.

Why Do We Think GDRX Will Underperform?

  1. Underwhelming customer growth over the past two years shows the company faced challenges in winning new contracts
  2. Modest revenue base of $799.9 million gives it less fixed cost leverage and fewer distribution channels than larger companies
  3. Push for growth has led to negative returns on capital, signaling value destruction

GoodRx’s stock price of $3.58 implies a valuation ratio of 8.4x forward P/E. Read our free research report to see why you should think twice about including GDRX in your portfolio.
