recent data breach is

notable in many ways and can impact investor sentiment across the entire stock market, Max Wolff, chief economist at Disruptive Technology Advisers, argued during a recent

CNBC "Trading Nation" segment.

, investors will likely be looking at any and every company in their portfolio and asking what are the potential cyber-vulnerabilities, he continued. Companies will likely be forced to make it even clearer now what policies are in place to not only prevent but respond to these types of attacks.

Equifax knew about a data breach for two months during which time executives were "getting ready to share the information that they had lost this data."

Equifax CEO: 'We Apologize'

Equifax's CEO Richard Smith wrote an open letter to the public, which was published on

USA Today

. In the letter, the executive said that the data breach was "painful" and "the most humbling moment" in the company's century-old history.

The company initially discovered the breach on July 29 and it is natural for the public to be questioning why there was a six-week delay since the company publicly confirmed a data breach, the executive wrote. At first, it was believed the intrusion was "limited" and outside investigators confirmed there was no unauthorized activity on the consumer or commercial credit reporting databases.

"Consumers and media have raised legitimate concerns about the services we offered and the operations of our call center and website," he wrote. "We accept the criticism and are working to address a range of issues."

Finally, the executive said the company is allocating "extraordinary resources" to ensure there is no future data breach and every consumer who "wants protection has a full package of services."
