Today, large-cap stocks are in the spotlight.These are stocks of companies with market capitalizations of over $10 billion that rank near the top of all stocks rated by our proprietary quantitative model, which looks at more than 62 factors. In addition, the stocks must be followed by at least one financial analyst who posts estimates on the Institutional Brokers' Estimate System. The stocks are ordered by their potential to appreciate.
