Since the Federal Reserve began a new cycle of raising interest rates in March, US stocks have entered a period of continued volatility, and investors have also sold their stocks.

Buffett, who always adheres to "I am greedy when others are afraid", is once again practicing his investment principle and is plagiarizing the bottom of US stocks.

In the first quarter of this year, Berkshire bought more than $51 billion of shares, including Chevron Corp, Hewlett-Packard and Occidental, when the market plummeted, according to the latest 13F documents. Among themChevron Corp was promoted to Berkshire's fourth largest stock, while Western Oil parachuted into the eighth largest stock.

After a decade of hardship,Energy stocks are the biggest winner in the U. S. stock market this year.Among them, western oil is up more than 130% this year, Chevron Corp is up nearly 50%, and the s & p 500 index is down nearly 16% over the same period.

So, what is the magic of energy stocks to attract "stock gods" to keep increasing their positions?

In the eyes of Wall Street, energy stocks are still undervalued, strong fundamentals, improved credit conditions, large dividends and anti-inflationary nature, are becoming an excellent hedge against high inflation and geo-crisis.

Jim Shanahan, senior stock research analyst at Edward Jones, saidEnergy stocks fit two of Buffett's traditional preferences: low valuations and dividends in the form of share buybacks and cash dividends.

Apart from the sector, high-dividend stocks have also significantly outperformed the S & P 500 this year, in part because investors are looking for stocks that offer stable cash returns in volatile markets."Chevrolet and Western oil fit this characteristic. "Shanahan said.

According to Tianfeng Securities, the operating cash flow of shale oil companies improved significantly in 2021, driven by rising oil prices. The top five shale oil companies have an operating cash flow of US $32.5 billion in 2021. In addition to 38% for CAPEX, a larger proportion (32%) is used to repay debts, followed byFor dividends (17%) and buybacks (5%).

In addition, Rupal Bhansali, chief investment officer for global equities at Ariel Investments, believes thatUncleKahill's investments in Chevron Corp and Western Oil are the main hedge against inflation and reflect Berkshire's bet that commodity prices will remain high for some time.

Oil assets have been widely deployed as inflation hedges and have proved to be profitable investments in times of geopolitical turmoil.
