At the end of every quarter, publicly traded companies announce their profits and losses in an earnings report. These updates provide insight into a company’s performance and, in theory, give investors and shareholders clarity on whether to buy, sell or hold. If earnings are good, the stock price may soar. If they’re down, the price might plunge.

However, the implications for the stock price may not be immediately clear to all investors. In the face of this uncertainty, sellers will ask for high prices, and buyers will offer low ones, creating a significant “bid-ask spread.” When this happens, it becomes more costly to trade, and the stock becomes less liquid.

This is a well-documented effect on equity stock markets. However, according to research by Stefan Huber (Rice Business), Chongho Kim (Seoul National University) and Edward M. Watts (Yale SOM), the corporate bond market responds differently to earnings news. This is because bond markets differ from stock markets in a significant way.

Stocks v. Bonds: What Happens When Earnings Are Announced?

Equities are usually traded on centralized exchanges (e.g., New York Stock Exchange). The exchange automatically queues up buyers and sellers according to the quote they’ve entered. Trades are executed electronically, and the parties involved are typically anonymous. A prospective buyer might purchase Microsoft shares from someone drawing down their 401(k) — or they could be buying from Bill Gates himself.

Corporate bond markets work differently. They are “over-the-counter” (OTC) markets, meaning a buyer or seller needs to find a counterparty to trade with. This involves getting quotes from and negotiating with potential counterparties. This is an inherent friction in bond trading that results in much higher costs of trading in the form of wider bid-ask spreads.

Here’s what Huber and his colleagues learned from the research: Earnings announcements prompt many investors to trade. And on OTC markets, potential buyers and sellers become easier to find and negotiate with.

A Stronger Bargaining Position for Bonds

According to Huber, “When earnings information comes out, a lot of people want to trade. In bond markets, that makes it much easier to find someone to trade with. The more options you have to trade, the stronger your bargaining position becomes, and the lower your trading costs go.”

He compares the process to shopping in a market with a flexible approach to pricing.

“Let's say you're at a farmers market and you want to buy an apple,” Huber says. “If there is only one seller, you buy the apple from that person. They can ask for whatever price they want. But if there are multiple sellers, you can ask around, and there is potential to get a better price. The price you get depends on the number of options you have in trading partners.”

What’s at Stake?

Although bonds receive less attention than equities, the stakes are high. There is about $10 trillion in outstanding corporate debt in the U.S., and more than $34 billion in average daily trading volume.

A detailed record of bond trades is available from the Financial Industry Regulatory Authority (FINRA), which requires that trades be reported via their Trade Reporting and Compliance Engine (TRACE).

The study from Huber and co-authors uses an enhanced version of TRACE to examine trades executed between 2002 and 2020. The team analyzed the thirty-day periods before and after earnings announcements to gather data about volume, bid-ask spreads and other measures of liquidity.

They find that, like on the stock market, there are more investors and broker-dealers trading bonds around earnings announcements. However, unlike on the stock market, transaction costs for bonds decrease by 6 to 7 percent in the form of bid-ask spreads.

What Sets This Research Apart?

“Taking a purely information asymmetry-based view would predict that what happens to stock liquidity would also happen to bonds,” Huber says. “A piece of information drops, and some people are better able to work with it, so others price protect, and bid-ask spreads and the cost of trading go up.”

“But if you consider the search and bargaining frictions in bond markets, you get a more nuanced picture. While information asymmetry increases, like it does on stock markets, the information prompts more investors into bond trading, which makes it easier to find counterparties and get better transaction prices. Consequently, bid-ask spreads go down. This search and bargaining friction does not really exist on equities exchanges. But we cannot ignore it in OTC markets.”

As corporate debt markets continue to grow in importance, it will become crucial for investors and regulators to understand the nuanced factors influencing their liquidity. This study provides a solid foundation for future research.

Houston founders launch edtech startup, pilot to pinpoint why students are struggling

learning gaps

Early detection. It sounds simple enough: identify a problem before it has the chance to become a bigger one.

But in practice, early detection is much more difficult to navigate, especially in education, when it comes to identifying the reasons behind a student's academic struggles.

That’s why co-founders Alapati “Al” Ware and Estela Montanez launched Progress Report, a Houston-built K-12 learning-intelligence platform designed to go beyond identifying that a student is struggling.

The platform recently began its pilot program with 35 educators and more than 200 students in Texas and Arizona.

“It’s a micro-learning school that works with children with disabilities, primarily dyslexia and nonverbal students,” Ware tells InnovationMap.

The platform is also being used by homeschool parents, home teachers and Houston educators, including those at SWPS College & Career Preparatory Academy, a Houston charter school.

Ware says Progress Report was designed to fill a gap he and Montanez saw in existing edtech. Some platforms cater almost entirely to students, leaving teachers with little insight into if and how a child is learning. Others focus heavily on district data, where “the student is just a number,” leaving teachers to navigate disconnected tools.

“Our goal was [to] focus purely on the teacher because the teacher is the backbone,” Ware says.

Progress Report traces student performance to learning gaps and prerequisite skills, helping educators understand not only where a student is struggling, but what may be causing it.

The platform then helps teachers build individualized instruction for general education students, students with special education and Individualized Education Program (IEP) needs, and Spanish-speaking learners—all within one educator-controlled system.

The goal is to reduce the guesswork and hours of manual work educators can spend developing individualized lesson plans.

For Ware and Montanez, the mission is also personal.

The concept dates back to around 2023, when the co-founders first had to navigate and address their children’s educational needs.

Ware, Progress Report’s CEO and CTO with a background in edtech, built the platform end-to-end after watching his daughter, who had an IEP related to speech, struggle to get the support she needed.

Montanez, the company’s COO, brought another perspective. Her son is on the autism spectrum. She now leads Progress Report’s operations, partnerships and pilot execution while helping carry its focus on bilingual families from Puerto Rico to Houston.

Together, they began researching ways to personalize their children’s learning and help them progress academically. Montanez’s son went on to become an AP student and high school athlete, while Ware’s daughter began reading more than two grade levels above her grade, they tell InnovationMap.

But Progress Report isn’t designed simply to give a struggling student more work.

Take a student who appears to have difficulty with math.

The problem may not actually be math, the founders share. The student could understand the calculations but struggle to comprehend complex words used in a math problem.

Progress Report is designed to trace those performance patterns back to learning gaps, prerequisite skills or other instructional barriers. From there, it can recommend a next instructional step while leaving the educator in control.

The same concept applies to accommodations.

The system can read IEPs, 504 Plans, Present Levels of Academic Achievement and Functional Performance (PLAAFPs), evaluations and other special education records. Approved IEP goals can then be mapped into the student’s learning graph, while accommodations can carry over into lesson planning and question delivery.

The founders say that approach separates Progress Report from simply adding another artificial intelligence chatbot to a classroom. And still, they believe teachers have to remain at the center.

Teachers, in fact, helped build Progress Report.

The founders began meeting with Houston-area educators months before the pilot. Their feedback helped shape the platform before testing began.

“We’ve been building alongside these educators,” Ware says.

Parents are another piece.

Progress Report can give parents access to their child’s learning record so they can see learning gaps as they develop. Teachers can also see information on work being completed at home when the parent and educator are working together.

After the pilot wraps, Ware and Montanez plan to introduce a $29.99 monthly subscription for homeschool parents, teachers and other educators. They say the price was intentionally kept relatively low to help make the tools more accessible.

They are also exploring ways to work with organizations that could help families who can’t afford the platform.

Moving forward, the goal is considerably bigger.

Over the next five years, Ware and Montanez want Progress Report to become what they describe as a “gold standard” in every state. They know getting there will require building relationships with educators, technology leaders, policymakers and school board members.

For now, they’re starting with a few hundred students and a question that sounds simple but can be remarkably difficult to answer: Why is this student struggling?

If Progress Report works the way its founders envision, teachers and parents will have a clearer answer.

Pioneering cohousing development opens in Houston's historic 2nd Ward

Housing in Hou

An experimental, multi-generational building in the East End is now open and accepting residents. Only 10 of the 33 units remain available at East End Commons, the first project from CoHousing Houston.

Located at 115 Lenox, East End Commons was first conceived in 2017 and is designed to combine the security of home ownership with the community aspect of apartment life, essentially a condominium but with added focus on bringing neighbors together.

Units range from 900-2,000 square feet, offering ample private home space, but with a large Common House area and central courtyard for gatherings, working, and interaction. Large front porches encourage people to spend time outside where they can meet their neighbors, as do extensive foot paths for casual meetings.

"At East End Commons, you know your neighbors before you move in — so you have a network of people and spaces that are immediately there for you," said founding resident Kelli Soika. "We designed for larger shared spaces versus larger personal spaces in order to foster the breakdown of the barriers that lead to loneliness."

Combating loneliness and isolation is certainly necessary. A 2025 survey conducted by the American Psychological Association shows that most Americans feel a sense of societal division and lonely. A loss of "third spaces," where people gather outside the home or work, is a prime factor. East End Commons aims to alleviate some of that disconnectedness.

"I wanted to live in a neighborhood that is imbued with a sense of community above the individual, like we have all experienced in Houston during times of disaster recovery," said Lynn Morstead, one of East End Commons‘ founding residents. "In those instances, such as Hurricane Harvey, we surface from our separateness and come together in new and unexpected ways. With East End Commons, the goal is to translate that notion beyond a set period of time and make it a fixture of everyday life. I call it 'disaster-free neighborliness.'"

East End Commons was designed by Kathleen English of English + Associates. Sustainability is part of the project's design, with amenities such as geothermal heating and cooling exchange HVAC, pre-heated water systems, low-energy use air conditioning and heating, and native landscaping.

Prices for units range from $300,000 to the $900,000s, which can be more than double the home price in the rapidly gentrifying East End. HOA fees not only help maintain communal areas, they also cover shared internet, water, and other communal expenses. Similarly, government of the building is handled democratically via a community board that aims to make decisions by building consensus.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.
