This article is about people on a TV show talking about what stocks they think are good to buy or sell. They talk about two big companies and one type of fund that has many small companies in it. One person likes Berkshire Hathaway because it's led by Warren Buffett, who is very successful at making money with his company. Another person likes a fund that has smaller companies that can grow and make more money. Read from source...

1. The author fails to mention that Berkshire Hathaway is a conglomerate holding company and not a pure play on Warren Buffett's investment strategy or stock picking abilities. This means that the performance of the company depends on many factors beyond his control, such as its diverse portfolio of businesses, acquisitions, dividends, etc.
2. The author cites UBS analyst Brian Meredith who raised the price target for Berkshire Hathaway from $435 to $477 without providing any reasoning or analysis behind this change. This suggests a lack of critical thinking and blind reliance on Wall Street's opinions.
3. The author does not challenge Shannon Saccocia's claim that she picked iShares Core S&P Small-Cap ETF for "profitable ones that are able to grow their earnings against this backdrop". This statement is vague, unsupported and potentially misleading, as it implies that all small-cap stocks in the index are profitable and have growth potential, which is not necessarily true.
4. The author does not disclose any conflicts of interest or personal bias that may influence his recommendation of iShares U.S. Oil & Gas Exploration & Production ETF by Joshua Brown of Ritholtz Wealth Management. This raises questions about the credibility and objectivity of the source and the validity of his argument.
