These 2 Sectors Comprise 71% of Warren Buffett's Portfolio: Are They Recession-Resistant?

Warren Buffett is a master investor, with the wealth and track record to prove it. He's been investing successfully for decades on his own terms, often with heavy concentrations in sectors and individual stocks.

Buffett has openly labelled diversification as a technique that's only needed by less-skilled investors. The portfolio at Berkshire Hathaway, the company Buffett runs, reflects that belief. Specifically, two sectors account for 71% of Berkshire's holdings: technology and finance.

Diversification is a risk management strategy. The goal is to avoid having all your assets move in lockstep together -- which would create extreme portfolio volatility. You might not mind upside volatility, but no one likes downside volatility.
