Coursera and MOOC

I have recently signed up for a class on Coursera. The class is Computational Investing, Part I and so far I am having a great time.

The class is made up of video lectures, usually 10-15 minutes long, posted each week. The lectures are usually split in modules making it easy to break up your work on the class in small chunks. You do not have to lock up 2-3 consecutive hours to get the class down. I break up my work in small chunks based on free time.

MOOCs or massive open online courses have been around for a little while. They are a great way to start learning something new or increase your knowledge in a field you know well already. Sometimes just the collaboration with other students and having to do reading and homework is a great way to keep your brain sharp.

I may have a few more posts about this course in particular.

IT Cost Cutting on Wall Street

Wall Street’s Mission: Cutting Costs While Staying Competitive January 10, 2013 URL:

A flood of new regulations, coupled with falling profits from once-lucrative areas such as derivatives and equities trading, has Wall Street firms making some tough decisions.

First, they have to slash IT infrastructure costs as a way to boost the bottom line. While trimming budgets is never easy, it’s a process that’s familiar to all CIOs. A larger and tougher decision is to take a look at the entire IT infrastructure, as well as the existing business units, and decide what lines of business the firm should be in in the future. For instance, does the IT department continue to run separate market data databases for equities and derivatives? Does the firm even want to be in equities in the future?

“The general theme is more for less,” says Mark Akass, CTO at BT’s Global Banking and Financial Markets, part of BT Radianz, which operates a financial community network that lets members access 400 service providers, such as order management, trade execution and clearing. “People are looking to achieve more with the same budget. You have to find ways to operate and comply” with the newer regulations. “They have a double whammy,” he adds.


Extreme Makeover: IT Budget EditionWall Street & Technology’s January digital issue, which looks at how Wall Street firms, faced with a slew of new regulations and declining profits, are squeezing more out of their existing IT infrastructures, revisiting outsourcing relationships and modernizing costly legacy systems.

As a reflection of this trend, several brokerage firms plan to carry out massive layoffs to shrink their costs. On Dec. 5 Citigroup said it would cut 11,000 jobs worldwide to produce $1.1 billion in savings. Citi’s global consumer bank will lose 6,200 jobs, an additional 1,900 will be cut from Citi’s capital markets and transaction processing units, and 2,600 from back-office operations. About 3,400 of the cuts will come from technology and operations within those groups.

A New IT Budget Reality

Financial firms’ IT budgets are being hit from all directions. “That’s causing a shift in the IT mindset,” Akass says. The new mindset is going to involve revamping internal processes and hunting for efficiencies in every part of an organization, including architecture, software development, market data and connectivity.

The cuts will be necessary, but firms must continue to refresh their technology to remain competitive in areas such as low-latency trading. However, they also need to improve quality, as evidenced by the software error that nearly toppled Knight Capital Group in August.

“Cost reduction and improved quality are part of every interaction we have,” says Kirk Wylie, founder and CEO of OpenGamma, an open source risk management and analytics platform that caters to hedge funds. As the industry’s focus has changed from trading exotic derivatives to flow products with lower margins, the 3-year-old startup has caught the attention of a broad array of financial firms seeking real-time risk management, including small regional banks, global Tier 1 investment banks, insurance companies, fund administrators, as well as large and small hedge funds, Wylie says. Though the application is free to download, clients can get a maintenance contract for support and enhancements, which runs about $100,000 to $500,000 per year.

In the past, bigger firms have made incremental reductions in their IT spending, but now they’re changing their approach. “This is the new normal, and they need to make transformative cuts,” Wylie says. “They have to go in and say, ‘How am I going to cut 20% or 25% of my margins, because I’m never going to achieve the glory days of 2005 or 2006?'”

However, simply taking a hatchet to the IT budget isn’t a good idea, since companies must shift to newer technologies to remain competitive. New competitors, such as startup funds and small brokers, are using faster, more efficient technologies that have an inherent lower cost structure, putting pressure on the established players, says Bill Adiletta, partner in the technology practice at consulting firm Capco.

An established firm can invest capital to enter a low-latency trading business and two years later find a new entrant jumping in at half the cost. “The newer firm never had the sunk cost,” Adiletta says. The dilemma, he says, is “how do you keep advancing your technology fast enough to stay competitive … while figuring out how to write off the sunk capital?”

Streamlining software development life-cycle processes is key to increasing quality and cutting costs, Adiletta says. “If you revisit your development methodologies with quality inherently built into it, you can improve your time to market and lower cost,” he says. Given the technical snafus with the BATS IPO, Nasdaq’s debut of Facebook and more recently Knight Capital, firms have to be more attentive to quality, he says.

The focus on quality is why the industry hears so much talk about agile development, a software development process popular in other technology verticals, he says. Newer entrants are using rapid time to market, embedded disciplined quality management and other approaches to lower overall costs.

The Open Source Advantage

Another way firms are cutting costs is with open source technologies, which are free to license but can be customized to meet a company’s specific needs.

When Sanjib Sahoo, CTO at optionMonster and tradeMonster, launched an online trading platform in 2008, he turned to open source technologies. “We’re saving a ton of money,” he says.

The online brokerage runs its platform and infrastructure on the LAMP (Linux, Apache, My SQL and PHP) stack. By using MySQL instead of a commercial database, it has saved millions of dollars over the past three years, which is a significant percentage of its technology budget, Sahoo says. “I think we’re the only brokerage firm primarily running on open source,” says Sahoo, whose 60-person IT team develops everything in-house. The firm has had a 99.98% uptime, with reliability and scalability that meets the needs of active investors, he says.

OpenGamma’s Wylie agrees that there’s savings to be had from in-house development. “Any firm that’s done custom development will find that it can consume 46% of their total annual spend in risk and analytics,” he says. The first version could take 20 person-years and cost $250,000 per person-year, adding up to a $5 million project, he says. And the cost of maintaining, supporting and enhancing the system over its life could be 10 times the initial build cost.

However, Wall Street firms are wary of using open source for trading applications since they don’t want to contribute their proprietary code to the community, Wylie says. “The client doesn’t have to post anything to the community. Firms don’t have to open up their secret sauce to us, but just the stuff that has to talk to our code.”

New Financial Reality

Even with cost cutting, firms will still want to do their own internal development to capture a competitive advantage in whichever market segment they decide to pursue. “The financial game is changing, the margins are getting smaller and, the way the economy is, you have to be set up to trade across asset classes,” says Fintan Quill, senior engineer with Kx Systems, a provider of databases and tools for processing real-time and historical data.

Sun Trading recently expanded its use of Kx Systems’ kdb+ database to support cross-asset trading across new markets and geographies. It uses the platform to enter new markets when an opportunity arises. In contrast, firms with older systems built to handle just one asset class have a difficult time adapting to new markets. The Kx database’s real-time analytics and speed has let Sun Trading quickly bring trading ideas to the market, says CIO Kurt Lingel. Sun Trading plans to use Kx to address research and analysis needs as it continues to diversify across multiple asset classes and markets, he says.

Sun Trading’s Chicago and London offices will use the Kx database to capture and analyze large volumes of data in real time for quantitative trading. The move is cost effective because the firm is using the same hardware and staff for all the data, Kx’s Quill says. “They’re getting better bang for their buck by using one technology to house their data,” Quill says.

As specific trading teams look across different asset classes, it’s useful to have data in one system, especially if low latency is involved, he says. “If you’re doing a correlation trade between FX and something else, from a purely technological standpoint, you’ll get a faster return on investment, and you don’t need to develop a separate infrastructure,” says Quill.

As firms are driving toward efficiencies and being cost effective, it’s a prime time to ask what business you want to be in, says Capco’s Adiletta. There’s a big transition under way from simply trading equities to cross-asset trading, he says. In other words, as their business model changes, firms must capture more market opportunities by capturing more data. “When you look at transformation, it’s important to look at expanding your business model to other asset classes and methodologies,” he says.

To achieve a transformative reduction in infrastructure costs, experts suggest that firms will need to learn new ways of deploying infrastructure, such as leveraging the cloud. A hybrid operating model is one option in which firms no longer run dedicated infrastructure, says BT’s Akass. “They can maintain key parts of their infrastructure and integrate it with other companies,” he says. For example, industry-specific clouds, such as NYSE Technologies’ Capital Markets Community Platform and BT Radianz’s cloud, can provide connectivity to numerous exchanges and deliver data from multiple information providers, some of which sit within their own data centers. “They could save money by not having duplicate links and infrastructure,” Akass says.

But no matter what the specific business strategy is, whether it’s a multiasset trading approach or something else, firms need to reduce cost, complexity and time to market. Existing systems have powered the industry for decades, but new regulations and budget pressures are forcing CIOs to rethink all parts of their infrastructure spending.
