There are hundreds of trading strategies, there are over 6500 companies on the stock markets not including penny stocks and pink sheets.
As you can see by some of the other answers, your question needs be more definite, there to much to choose from with such vagueness.
Sorry I-75 Warren Buffet is not the smartest investor, he is good and consistent with his type of trading. But he never won any awards gaining 5-7% annual returns. When it comes to successful trading there are many categories and Warren Buffet is a very good trader, but you put him into a trading competition to figure out who has the highest annual returns and he will always come up short.
I kinda like Caterpillar (CAT) http://american-ticker.com/finance/ratio... They make construction vehicles. And there are also General Electric (GE), Google (GOOG), Intel (INTC), Merck (MRK), just to name a few great companies. There are probably about 400 or 500 hundred great companies out there. If you list your criteria, I can narrow a list of companies for you. For example, are they great because they treat their employees well? Or are they great because they are the fastest growing company based on revenue? Or maybe they are great because they've setup succession plans for their company that will take them into the next century? But most people simply use stock price appreciation as a reflection of the company being great.
companies with annual revenue and earnings growth greater than 20% each, annually. Low PE, P/S, and/or P/B stocks. if you want to be aggressive, stocks that are making new 52 week highs week after week.
Warren Buffett is the smartest investor ever. It is best to buy what he is buying, some examples are IBM, Walmart and General Motors.
growing companies with ideas, not afraid to try something new, like APPLE, or QUALCOMM or even INVN
growing profitable ones.
