Berkshire shares are suffering their longest losing streak in more than seven years
Berkshire Hathaway shares have lost ground for eight straight days.
It is their longest losing streak since eight consecutive defeats in December 2018.
The Class A Shares fell 4.7% and the Class B Shares have fallen 4.9% since their last daily rise on March 17.
Berkshire coincides with the overall market hit by rising energy prices and global uncertainty due to the Iran war.
While the S&P 500 index has not experienced a series of daily losses and is down 5.2% over the same period.

Berkshire’s year-to-date losses are close to the S&P’s 7% decline. The leading index is on a five-week losing streak.

Berkshire’s share prices have fallen more than 13% since Warren Buffett announced at last year’s shareholder meeting that he would step down as CEO at the end of 2025.
They are about 2% above their August lows, but have fallen below two other lows in early November and late January.

Berkshire’s new Japanese investment is rising in value
Berkshire Hathaway’s latest investment in Japan is off to a good start.
Shares of Tokyo Marine Holdings rose more than 24% this week after Monday’s announcement that Berkshire’s National Indemnity will pay $1.8 billion for a nearly 2.5% stake in Japan’s oldest insurer, which Barron’s calls “one of the best-run property and casualty insurers in the world.”
Today, Berkshire’s new purchase has a market value of nearly $2.3 billion.

The two companies will also collaborate in the reinsurance space and seek strategic investments globally.
In a press release from Tokio Marine, the company said Berkshire’s corporate culture and values ​​”align closely with those of our own.”
It added: “Importantly, this is not just a business alliance. We believe this creates a long-term strategic relationship, anchored by an equity investment, that will serve as a strong catalyst for the medium to long-term growth of both companies.”

Berkshire’s insurance chief Ajit Jain is quoted as saying: “We expect this strategic partnership to create compelling long-term opportunities for both organizations.”
According to Barron’s reports, Jain oversaw the investment “and likely involved former CEO Warren Buffett, who now serves as chairman.”
“The deal shows that Berkshire’s ability to write insurance remains undiminished, even though Buffett left the CEO post for Greg Abel. This bodes well for Berkshire, given the importance of insurance to the $1 trillion company.”
Tokio Marine issued new shares for Berkshire to purchase. It plans to buy back an equal amount of its already issued shares to prevent dilution for existing shareholders.
Berkshire is allowed to increase its stake to just under 10% through purchases on the open market. An increase would require the approval of Tokio Marine’s board of directors.
Insurance Business notes that Tokio Marine has spent more than $17 billion on acquisitions in the U.S. over the past two decades, including Philadelphia Insurance Companies and Delphi Insurance Group.
It is believed the new partnership could “accelerate this journey through Berkshire’s deal sourcing reach and reinsurance capacity.”
