1 Oversold Stock Set for a Comeback and 2 We Ignore

TENB Cover Image

The past year hasn't been kind to the stocks featured in this article. Each has tumbled to their lowest points in 12 months, leaving investors to decide whether they're witnessing fire sales or falling knives.

Price charts only tell part of the story. Our team at StockStory evaluates each company's underlying fundamentals to separate temporary setbacks from structural declines. Keeping that in mind, here is one stock where you should be greedy instead of fearful and two where the outlook is warranted.

Two Stocks to Sell:

Tenable (TENB)

One-Month Return: -0.4%

Starting with the widely-used Nessus vulnerability scanner first released in 1998, Tenable (NASDAQ: TENB) provides exposure management solutions that help organizations identify, assess, and prioritize cybersecurity vulnerabilities across their IT infrastructure and cloud environments.

Why Is TENB Not Exciting?

  1. Products, pricing, or go-to-market strategy may need some adjustments as its 10.5% average billings growth over the last year was weak
  2. Estimated sales growth of 7.5% for the next 12 months implies demand will slow from its two-year trend
  3. Operating margin expanded by 3.2 percentage points over the last year as it scaled and became more efficient

At $29.50 per share, Tenable trades at 3.5x forward price-to-sales. If you’re considering TENB for your portfolio, see our FREE research report to learn more.

Leslie's (LESL)

One-Month Return: -21.2%

Named after founder Philip Leslie, who established the company in 1963, Leslie’s (NASDAQ: LESL) is a retailer that sells pool and spa supplies, equipment, and maintenance services.

Why Is LESL Risky?

  1. Lagging same-store sales over the past two years suggest it might have to change its pricing and marketing strategy to stimulate demand
  2. 8.9 percentage point decline in its free cash flow margin over the last year reflects the company’s increased investments to defend its market position
  3. Limited cash reserves may force the company to seek unfavorable financing terms that could dilute shareholders

Leslie's is trading at $4.38 per share, or 11.4x forward EV-to-EBITDA. Read our free research report to see why you should think twice about including LESL in your portfolio.

One Stock to Buy:

Payoneer (PAYO)

One-Month Return: -10%

Founded during the early days of global e-commerce in 2005 to solve international payment challenges, Payoneer (NASDAQ: PAYO) provides financial technology services that enable small and medium-sized businesses to send and receive payments globally across borders.

Why Will PAYO Beat the Market?

  1. Market share has increased this cycle as its 25.6% annual revenue growth over the last five years was exceptional
  2. Performance over the past two years was turbocharged by share buybacks, which enabled its earnings per share to grow faster than its revenue

Payoneer’s stock price of $5.91 implies a valuation ratio of 20.5x forward P/E. Is now the time to initiate a position? Find out in our full research report, it’s free for active Edge members.
