NEW YORK (CNN/Money) - Berkshire Hathaway Inc., the holding company run by billionaire investor Warren Buffett, has refurnished its portfolio with 8 million of shares of home furnishing chain Pier 1 Imports worth about $141.5 million.

The purchase was disclosed in an SEC filing late Monday of Berkshire's latest quarterly holdings for the period ending July 30.

Pier 1 has about 87.4 million shares outstanding and a market capitalization of $1.5 billion.

Shares of Fort Worth, Texas-based Pier 1 (PIR: Research, Estimates) spiked more than 8 percent in early morning trading Tuesday.

Berkshire Hathaway's interest in Pier 1 was welcome news to investors after the retailer, plagued by sluggish sales, last week cut its second-quarter forecast and sent its shares tumbling to a new 52-week low.

Berkshire's largest holding, according to the filing, is beverage behemoth Coca-Cola Co. (KO: Research, Estimates), with 198.2 million shares valued at $10 billion. Berkshire also holds 151.6 million shares of American Express Co. (AMEX: Research, Estimates), valued at $7.8 billion.

Buffett's investment vehicle also owns 15 million shares of apparel retailer Gap Inc. (GPS: Research, Estimates) and 5.7 million shares of warehouse club operator Costco (COST: Research, Estimates).
