Warren Buffett's Berkshire Hathaway owned about $260 billion in cash and Apple stock at the last count, representing an astounding 52% of its $499 billion market capitalization.

The famed investor's conglomerate held about 245 million Apple shares as of June 30, giving it a roughly 5.7% stake in the iPhone maker. Apple's stock price has soared about 57% to an all-time high this year, boosting the value of Berkshire's position by more than $40 billion, to about $113 billion as of Tuesday's close.

Buffett's company also boasted a record $147 billion in cash and US Treasuries at the end of June, an increase of about $19 billion from the end of December.

Meanwhile, Berkshire's stock price is down about 9% this year, weighing on its market cap. By comparison, the S&P 500 and Nasdaq indexes both closed at record highs on Wednesday.

The outcome of Berkshire growing its cash pile and its Apple stock climbing in value while its market cap remains depressed is that its cash and Apple shares are now worth more than half of the entire company.

Berkshire has also ramped up its spending since the end of June. It agreed to pay about $4 billion in cash for Dominion Energy's natural-gas assets, plowed about $2.1 billion into Bank of America stock in the three weeks to August 4, and appears to have repurchased roughly $2 billion of its own stock in July.

However, that would still leave it with about $139 billion in cash and a total of $252 billion in cash and Apple stock, representing more than 50% of its market cap.

Berkshire's market value implies that without the Apple shares and cash, the rest of its business is worth less than $240 billion. That's hard to believe given the massive scale and diversity of its operations.

Buffett's company owns scores of businesses, including Geico, See's Candies, Dairy Queen, Duracell, Fruit of the Loom, NetJets, Precision Castparts, PacifiCorp, MidAmerican Energy, the BNSF Railway, and Marmon, which itself owns more than 100 manufacturing and services businesses.

Berkshire also generated about $254 billion in revenue and $69 billion in pretax income last year, excluding a roughly $34 billion gain on its Apple stock and about $750 million in dividends from the tech titan.

Moreover, strip out Berkshire's cash and Apple stock and it still boasted about $160 billion in net assets as of June 30.

Berkshire's market cap doesn't seem to reflect its size, asset base, and financial health. The company is exposed to the pandemic through its numerous insurance, manufacturing, retail, industrial, and service businesses, but its valuation still seems disconnected from reality.
