Regarding market cap, Apple takes the number 1 spot with Microsoft trailing behind. However, Amazon generates the most revenue out of the Top 10 and all of the companies in the Mag 7 group. All the companies are US-based with only Taiwan Semiconductor coming from overseas, which demonstrates the dominance of the US stock market.

In terms of current valuation, Eli Lilly is the most expensive as of today with a price-to-earnings ratio of 110. Meaning, investors who purchase the stock today are paying $110 for every $1 of profit generated by the company. However, if we look at its forward projected earnings, it looks much cheaper compared to today's valuation suggesting an opportunity for further growth. So the real question is, can the company meet its future projected earnings over a longer period?

Out of the Top 10 companies, Berkshire Hathaway is the cheapest based on P/E. Alphabet is the cheapest out of the Mag 7 group.

Overall, based on both the P/E and the FWD P/E valuations, Alphabet is seen as the cheapest stock right now with Meta and TSM coming in joint second.
