Learning from Warren Buffett

“From Warren Buffett, I’ve learned that excellence really is a discipline,” said Restieri. “Set a clear direction, stay true to your principles and execute patiently.”

Investor focus

According to the agency report, Berkshire has struggled to keep up with the evolving pace of the industry due to its sheer size, while also struggling to make new and significant acquisitions.

All eyes will now focus on Greg Abel, who is looking forward to making an impact on Berkshire Hathaway's trajectory. However, the agency report highlights that the investors are not expecting any seismic shifts.

“I think the investment community would likely applaud Greg’s management style to the degree that it sort of buttons things up,” CFRA Research analyst Cathy Seifert told the news agency. “And if it helps performance, that can’t really be faulted.”

Abel has been a close aide to Warren Buffett for a really long time and has played an active role in managing the companies within the conglomerate.
