Late last month, famed investor Warren Buffett dropped his annual shareholder letter at Berkshire Hathaway (NYSE: BRK-B) (NYSE: BRK-A). As usual, the letter was filled with valuable nuggets for investors, ranging from how the Tax Cut and Jobs Act lifted earnings to why investors should never borrow money to buy stocks.
Here's a look at three takeaways from Berkshire's 2017 annual letter that investors shouldn't overlook.
1. Searching for "huge acquisitions"
It's no secret that Berkshire's cash hoard has been mounting. By the end of 2017, Berkshire's war chest had grown from about $86 billion at the end of 2016 to $116 billion in cash and U.S. Treasury bills (with an average maturity of 88 days). Given Berkshire's prowess in putting cash to work in lucrative investments, this cash presents a massive opportunity for Berkshire shareholders. But until this cash is invested, it's not providing any material gains in Berkshire's book value.
Fortunately, Buffett is intent on putting this cash to work as soon as possible.
2. Irrational acquisitions
Speaking of acquisitions, one of the reasons Berkshire has failed to deploy its growing cash hoard is because it couldn't find large stand-alone businesses it wanted to own that traded at sensible purchase prices. "Indeed, price seemed almost irrelevant to an army of optimistic purchases," Buffett said about the current merger environment.
But what spurs the sort of environment in which prices rise to irrational levels? Buffett colorfully detailed the nonsense factors driving companies to make deals without giving price enough weight:
This culture, of course, was fueled by "ample availability of extraordinarily cheap debt," Buffett said.
3. The case against trading on margin
If you've considered buying stocks on margin or -- even worse -- already are, you may want to hear out a tip from the Oracle of Omaha: Don't do it.
In a table in Berkshire's annual shareholder letter, Buffett highlighted four times in which Berkshire stock dipped 37% or more. The most recent major pullback he highlighted was when Berkshire stock fell about 51% between September 2008 and March 2009. With volatility like this seen in a conservative stock like Berkshire, Buffett said this is why investors shouldn't borrow money to buy stocks.
As Buffett once advised value investor Mohnish Pabrai: Avoid leverage and be patient.
