3 Volatile Stocks We Steer Clear Of

MDB Cover Image

Volatility cuts both ways - while it creates opportunities, it also increases risk, making sharp declines just as likely as big gains. This unpredictability can shake out even the most experienced investors.

At StockStory, our job is to help you avoid costly mistakes and stay on the right side of the trade. Keeping that in mind, here are three volatile stocks to avoid and some better opportunities instead.

MongoDB (MDB)

Rolling One-Year Beta: 1.75

Named after "humongous database," reflecting its ability to handle massive data loads, MongoDB (NASDAQ: MDB) provides a flexible document-based database platform that helps developers build, deploy, and maintain modern applications more efficiently.

Why Does MDB Fall Short?

  1. Operating losses show it sacrificed profitability while scaling the business
  2. Free cash flow margin is forecasted to shrink by 2.2 percentage points in the coming year, suggesting the company will consume more capital to keep up with its competitors

At $323 per share, MongoDB trades at 10.3x forward price-to-sales. To fully understand why you should be careful with MDB, check out our full research report (it’s free).

Tesla (TSLA)

Rolling One-Year Beta: 1.69

Originally founded by Martin Eberhard and Marc Tarpenning in 2003, Tesla (NASDAQ: TSLA) is an electric vehicle company accelerating the world’s transition to sustainable energy.

Why Should You Dump TSLA?

  1. Tesla's scale advantage in EV production leads to gross margins that exceed incumbents such as General Motors and Ford. However, a softer macroeconomic backdrop and tariff pressures have weighed on automobile sales, which are highly cyclical.
  2. The company's execution ability is a question mark given its long history of delays, such as the Cybertruck and Robotaxi launches. Its sizeable investments in projects with uncertain return timelines, like Optimus, also raise skepticism from investors.
  3. On the bright side, Tesla's Megapack product solves a critical problem for utilities needing renewable energy storage solutions. This innovation has made the energy segment the most profitable and fastest-growing business line for the company.

Tesla is trading at $345.60 per share, or 164.7x forward price-to-earnings. Check out our free in-depth research report to learn more about why TSLA doesn’t pass our bar.

Morgan Stanley (MS)

Rolling One-Year Beta: 1.53

Founded in 1924 during the post-WWI economic boom by former JP Morgan partners, Morgan Stanley (NYSE: MS) is a global financial services firm that provides investment banking, wealth management, and investment management services to corporations, governments, institutions, and individuals.

Why Is MS Not Exciting?

  1. Earnings per share lagged its peers over the last five years as they only grew by 9.2% annually
  2. Scale is a double-edged sword because it limits the firm’s capital growth potential compared to its smaller competitors, as reflected in its below-average annual tangible book value per share increases of 1.6% for the last five years
  3. High debt-to-equity ratio of 5× shows the firm carries too much debt relative to shareholder equity, increasing bankruptcy risk

Morgan Stanley’s stock price of $148.85 implies a valuation ratio of 16.6x forward P/E. If you’re considering MS for your portfolio, see our FREE research report to learn more.
