Volatile markets look a lot like high-stakes poker games. Wild swings make it hard to chart a course to profitability, inevitably forcing some firms to fold. At the same time, there are always investors and firms that come out as big winners. So is there is a secret to drawing a winning hand in bad times?

Working with colleagues Evgeny Lyandres of Boston University and Alexei Zhdanov of Pennsylvania State University, Rice Business professor Gustavo Grullon hypothesized that the secret to surviving market volatility has to do with managers' ability to adjust operations. The more flexibility managers have to change the course of their firms, the reasoning went, the greater the likelihood of surviving market volatility, and in some cases taking advantage of it.

Consider Amazon, founded in 1994 with the goal of becoming "the world's most consumer-centric company, where customers can come to find anything they want to buy online." From its start as a bookstore, the company turned into an ultra-diversified behemoth that can shrug off vast swings in the market. Despite high volatility in recent years, Amazon's stock price increased roughly 39 percent, from $1,901 to $2,641, over the past year.

Grullon and his colleagues theorized that having more real options ⁠— managerial choices about tangible assets such as inventory, machinery or buildings ⁠— boosts firm value in a whole range of volatile circumstances, whether demand-based, cost-based or profit-based. Firms that have these options ⁠— Amazon, for example ⁠— can act fast to mitigate bad news by changing operating and investment strategies. They might cut production, shutter operations or delay investments. Companies without these tools basically have to ride fate's rollercoaster.

To test their theory, the researchers compared firms with a plethora of investment opportunities to those with more modest real options. They analyzed returns data from 1963 to 2018 from The Center for Research in Security Prices and from Compustat ⁠— a database of financial, statistical and market information about active and inactive U.S. companies.

Grullon and his team found there was measurable value in having more real options. A bigger spread of real options allowed managers to change strategy as soon as new information arrived. The greater the number of real options, the greater the flexibility managers had at their disposal when the market got volatile.

Developing Amazon-type options and diversified assets, naturally, takes years of sweat, trial and a measure of luck. Companies that do best at creating such opportunities, the researchers note, tend to be highly sensitive to changes in volatility to begin with, leading to more opportunities to adapt. Overall, the team found, volatility-return relation was much stronger in industries already characterized by plenty of growth and strategic options. High-tech firms, pharmaceutical companies and biotech companies, for example, show especially strong resistance to idiosyncratic volatility.

In other words, while volatile markets can resemble high-stakes poker, there are a few predictable rules. When the chips are down, companies that are lucky enough to hold diversified assets, have varied investment options and can shuffle resources quickly will be the strongest players at the table.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota
