2 Volatile Stocks Worth Investigating and 1 We Find Risky

BILL Cover Image

A highly volatile stock can deliver big gains - or just as easily wipe out a portfolio if things go south. While some investors embrace risk, mistakes can be costly for those who aren’t prepared.

These stocks can be a rollercoaster, and StockStory is here to guide you through the ups and downs. Keeping that in mind, here are two volatile stocks that could reward patient investors and one that might not be worth the risk.

One Stock to Sell:

EVgo (EVGO)

Rolling One-Year Beta: 0.91

Created through a settlement between NRG Energy and the California Public Utilities Commission, EVgo (NASDAQ: EVGO) is a provider of electric vehicle charging solutions, operating fast charging stations across the United States.

Why Does EVGO Fall Short?

  1. Historical operating margin losses point to an inefficient cost structure
  2. Cash-burning history makes us doubt the long-term viability of its business model
  3. Limited cash reserves may force the company to seek unfavorable financing terms that could dilute shareholders

EVgo is trading at $3.90 per share, or 32.6x forward EV-to-EBITDA. Dive into our free research report to see why there are better opportunities than EVGO.

Two Stocks to Watch:

Bill.com (BILL)

Rolling One-Year Beta: 1.58

Started by René Lacerte in 2006 after selling his previous payroll and accounting software company PayCycle to Intuit, Bill.com (NYSE: BILL) is a software as a service platform that aims to make payments and billing processes easier for small and medium-sized businesses.

Why Are We Positive On BILL?

  1. Average billings growth of 15.3% over the last year enhances its liquidity and shows there is steady demand for its products
  2. Software is difficult to replicate at scale and results in a stellar gross margin of 84.5%
  3. Software platform has product-market fit given the rapid recovery of its customer acquisition costs

At $45.44 per share, Bill.com trades at 2.9x forward price-to-sales. Is now the right time to buy? Find out in our full research report, it’s free.

Globalstar (GSAT)

Rolling One-Year Beta: 1.60

Known for powering the emergency SOS feature in newer Apple iPhones, Globalstar (NASDAQ: GSAT) operates a network of low-earth orbit satellites that provide voice and data communications services in remote areas where traditional cellular networks don't reach.

Why Are We Fans of GSAT?

  1. Annual revenue growth of 20.7% over the last two years was superb and indicates its market share increased during this cycle
  2. Incremental sales significantly boosted profitability as its annual earnings per share growth of 33.7% over the last two years outstripped its revenue performance
  3. Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends, and its rising cash conversion increases its margin of safety

Globalstar’s stock price of $26.72 implies a valuation ratio of 31.7x forward EV-to-EBITDA. Is now the time to initiate a position? See for yourself in our full research report, it’s free.
