CNBC looked for high-conviction names held in Buffett's stock portfolio through the end of September, according to the Berkshire Hathaway Portfolio Tracker . Then, we screened for stocks with the biggest upside to their average analyst price target.

Buffett started buying oil giant Occidental Petroleum last year, amassing a stake north 20% after receiving regulatory approval to purchase as much as 50% of the company. Occidental was the best performing stock in the S & P 500 benchmark in 2022, up more than 100%.

Analysts also have high hopes for e-commerce giant Amazon , forecasting the stock to advance nearly 18% in the next 12 months. Berkshire owned a $1.2 billion stake in the company as of September. Amazon on Thursday reported better-than-expected revenue for the fourth quarter, but issued first-quarter guidance that came in light of estimates.
