Cloud software stocks suffered a reversal that has produced losses of close to 50% from record highs.

The story for those stocks hasn’t changed, but the valuations have, and that could be a good thing for investors who know what they own.

The biggest risk for investors in cloud stocks isn’t the losses that have pummeled prices over the past two weeks, but rather the big reversal that may scare them away from the sector. It’s painful to watch large declines in stocks, yet nobody wants to miss out on a potential 10-bagger either. When the market rewards, and penalizes, all cloud software stocks equally, with little differentiation, it’s prudent to choose a select group that has compelling stories for a buy-and-hold strategy.

An investing adage is to buy when others are fearful. I would say to buy when others can’t differentiate among companies. Clearly, from what we saw over the past two weeks, a broad range of companies are being lumped together, with little recognition as to which are the winners.

To put it simply, this is a great time to know what you own as the story for these stocks is much deeper than the simple descriptor of “cloud software.”

In the graphic above, the orange line represents the First Trust Cloud Computing ETF SKYY, +0.12% which holds about 60 positions, all of which dominate the cloud space. The light-blue line is the Consumer Staples Select Sector ETF XLP, +0.41%, which tracks the consumer staples sector, a group that’s thought to be impervious to recessions. Those have historically been the laggards in this long, growth-driven bull market. The dark purple line is the benchmark S&P 500 Index SPX, +0.29%.

Before the stock market correction in May, cloud stocks were the leader in the market, while the staples were trailing. However, since that first correction, and up till today, there’s been a reversal. Over the past week high-growth leaders in this bull market, mostly cloud, have taken big hits.

For example:

Workday WDAY, -1.26% is down 25% from its high. Twilio TWLO, +3.08%, down 26%. Okta OKTA, -0.20%, down 22%. Zoom ZM, +1.02%, down 27%. MongoDB MDB, -1.57%, down 29%. PagerDuty PD, -0.38%, down 47%. (All prices are current as of 2 p.m. Eastern time Sept. 11.)

Cloud software categories

To start, cloud software needs to be broken up into categories to look more closely at the markets they serve. Here are some examples:

• Twilio is at the intersection of communications and mobile.

• CrowdStrike CRWD, +0.80% and Okta are security companies.

• PagerDuty simplifies operations, and Workday simplifies human resources and the finance department.

• Alteryx AYX, -0.74% and Splunk SPLK, +0.02% are big data analytics.

• Salesforce CRM, +0.43% is customer relationship management (CRM), but the market it serves is the sales and marketing industry.

• Zoom simplifies communications for enterprises and business-to-business (B2B), as does Slack WORK, +1.47%.

• Veeva Systems VEEV, -0.08% serves the life sciences and pharmaceutical industry.

Twilio has more in common with Skype, and even Verizon VZ, +0.50% and AT&T T, -0.93%, than it does with Okta. Workday has more in common with SAP and Oracle ORCL, -4.26% than it does with Alteryx. Yet, cloud stocks experienced a categorical black swan as if they all serve the same markets.

What this means is that some investors don’t understand these companies. The viability of a company’s product and how it fits the market is not factored into the investments, and this is creating a window of opportunity for investors who take the time to study individual stocks.

Valuations

The more logical explanation is that there was a clearance sale for overpriced stocks, and the common denominator in the sell-off was high valuations. However, the issue with this theory is that some of the companies will go on to be big winners, and higher price-to-sales (P/S) or enterprise-value-to-sales (EV/S) ratios are warranted because of the enormous markets they serve in contrast with their small size.

For instance, Zoom’s P/S and EV/S are gut-wrenching (no argument there), but the company’s revenue growth is unusual. You’d be hard-pressed to find triple-digit revenue growth for eight straight quarters in the stock market. The prospects of disrupting Cisco and other enterprise telecommunications at a $22 billion market cap is worth more than other companies that are serving smaller, more saturated markets. Zoom’s rapid growth, which is unprecedented, makes it hard to pinpoint a fair valuation.

Workday is another example of a company that carries high P/S and EV/S ratios, in this case twice as high as its large competitors, Oracle and SAP. In this scenario, you get a pure-play option that is moving quickly on machine learning to reduce the overhead required in human resources and finance departments. What Workday’s software aims to do, which is to reduce the number of employees needed in those departments, delivers a value that is worth many times over the cost of the software. If Workday is successful, the company will be worth much more than two times its current market cap, whereas, Oracle and SAP are essentially defending territory.

See: Beth Kindig runs a forum on tech stocks where she answers readers’ questions.

Splunk has P/S and EV/S ratios of eight compared with Alteryx’s 24 and 22, respectively, yet both were affected by the sell-off despite being in similar markets. Splunk should have held steady if this was a clearance sale on high valuations.

The evidence doesn’t point to a rational reason for the sell-offs. Some stocks are priced high, but knowing which ones deserve to be is going to be more important than ever.

How to evaluate cloud software

• The larger the market, the safer the investment. Can every enterprise employee in the world use the product for maximum scale? Does the product solve a pain and reduce overhead for businesses? These will outlast the more niche markets and products that are considered a convenience. To illustrate, if you are providing software for office communications that replaces office telecom equipment, not only is your product a necessity but it will be the solution to high telecom bills during a time when costs are being cut. There are numerous examples of fulfilling a (non-negotiable) necessity while reducing costs in the cloud software category.

• Ignore earnings estimates. Many estimates were lowered this past year, and when companies “beat” earnings estimates, they were actually declining year-over-year, sometimes substantially. Apple AAPL, -0.23% is a prime example of this. The stock continues to reach all-time highs and “beat earnings” despite two straight quarters of negative growth and mere 1% growth in the most recent quarter. That may work for Apple, but smaller-cap companies that are declining won’t last long, especially in a value rotation. Another example is Okta, which I believe had weakening fundamentals yet beat earnings estimates. Okta is now one of the hardest-hit cloud software stocks over the past two weeks, with a 22% drop since the end of August.

• We hear a lot about competitive moats, yet high switching costs is a protective buffer that serves two purposes: It locks in subscription revenue and staves off competitors. Often, switching from a cloud software provider will cost a customer time and resources. Look for companies that have high switching costs.

My prediction is this may be one of the last cycles when tech is considered less safe than value stocks. As the market will find out (the hard way), cloud software is actually very safe. It is insulated from trade wars and overseas manufacturing issues. It reduces costs for enterprises, which is ideal for a recession. Lastly, cloud software is at the beginning of a rapid growth cycle compared to its counterparts in tech — such as mobile, e-commerce and advertising — which are reaching saturation, are finding themselves in the cross hairs of anti-trust and are susceptible to consumer spending changes.

The best companies in the category of “cloud software” will continue to post rapid growth regardless of economic conditions, and the investors who run from this sector will suffer bigger losses from missed opportunities than investors who know their winners.
