A company called Alphabet, which is part of Google's parent company, and another company called Microsoft are two big companies that people watch because they can make a lot of money or lose a lot of money. The article also talks about three other stocks, which are pieces of ownership in different companies, that people might want to pay attention to on Tuesday. One of these stocks is Super Micro Computer, which makes special computers and did really well recently. Another one is General Motors, a big car company that will tell everyone how much money they made or lost soon. The last one is a group of insurance companies that Jim Cramer, a famous person who talks about stocks, thinks are not doing very good. Read from source...

1. The title of the article is misleading and sensationalist, as it implies that Alphabet, Microsoft, and three other stocks are the only ones to watch heading into Tuesday, when in reality there are thousands of other stocks that could be relevant for investors. A more accurate and informative title would be "Alphabet, Microsoft, And Three Other Stocks Among The Ones To Watch Heading Into Tuesday".
2. The article does not provide any context or background information on why these four stocks are particularly important or interesting to watch, other than mentioning their after-hours trading movements. A more comprehensive and insightful introduction would explain the factors that are driving the market attention to these stocks, such as earnings reports, mergers and acquisitions, regulatory changes, etc.
3. The article does not provide any analysis or opinion on the actual performance or prospects of these four stocks, other than reporting their share prices and earnings estimates. A more valuable and engaging article would offer some insights into the strengths and weaknesses of each company, their competitive advantages, their growth opportunities, their risks and challenges, etc.

The sentiment of the article is bullish.
