Although the stock market continues to plunge in a seemingly endless freefall, some investment experts are recommending shares in companies that can survive the volatility.

Canaccord Genuity recently pointed out to Barron’s that there are four software stocks that can stay afloat in a plunging market:

“We are in a ‘half empty’ versus ‘half full’ market, therefore getting the fundamentals right is even more critical,” analyst Richard Davis wrote Monday, Barron’s reported.

The average software stock has fallen from a multiple of six times forward enterprise value to revenue from nine times earlier this year, Davis wrote, according to Barron’s.

In a falling market “capital preservation is key,” he wrote. “That’s why we still suggest hiding out in a portfolio heavily weighted to growth and free cash flow profits.”

Here are his four software picks that fit his requirements:

• Microsoft (MSFT).
• Dropbox (DBX).
• Twilio (TWLO).
• HubSpot (HUBS).

To be sure, President Donald Trump suggested that a recent swoon in U.S. stock markets is a buying opportunity for investors, even though many analysts blame his policies and Washington gridlock for the plunge.

“We have companies -- the greatest in the world, and they’re doing really well,” Trump told reporters at the White House on Tuesday.

“They have record kinds of numbers. So I think it’s a tremendous opportunity to buy. Really a great opportunity to buy,” he was quoted by Bloomberg as saying.
