Which ones don't?
Intraday "trading" calls? Newsletter, fax, email, TV?
Calls on what? Bonds, futures, forex, commodities, stocks, options?
The question is pointless anyway. Nobody, not one single person, ever, has been able to predict future price or direction or extent any better than a coin toss. Predictions are of no value.
"Despite what these professionals claim, it is not actually possible to predict the movement of stocks and other financial instruments. According to William J. Bernstein's book "The Four Pillars of Investing," market strategists have historically been incorrect about 77% of the time.

Anyone tells you they know the future, just steer clear. These results are more detrimental than helpful. There are no psychics in the financial markets, or the real world excluding TV.
The best way to learn is by reading a good book or three, like Investing for Dummies and the Millionaire Next Door to get a feel for the markets. Then branch out. Learn good investing strategy and good trading strategy. There are no shortcuts to success.
Maybe try the Warren Buffet way, taught to him by Benjamin Graham. Graham wrote "The Intelligent Investor", illustrating the fundamentals of a value-investing strategy.
Graham instilled the fundamental principles of value investing into Buffett - principles upon which he relied to amass one of the world's largest personal fortunes.

I'm making good profit with penny stock

Many new investors are lured to the appeal of a penny stock due to the low price and potential for rapid growth which may be as high as several hundred percent in a few days. Similarly, severe loss can occur and many penny stocks lose all of their value in the long term. Accordingly, the SEC warns that penny stocks are high risk investments and new investors should be aware of the risks involved but you can even make very big money. These risks include limited liquidity, lack of financial reporting, and fraud. A penny stock is a common stock that trades for less than $5 a share. While penny stocks generally are quoted over-the-counter, such as on the OTC Bulletin Board or in the Pink Sheets, they may also trade on securities exchanges, including foreign securities exchanges. In addition, penny stocks include the securities of certain private companies with no active trading market. Although a penny stock is said to be "thinly traded," share volumes traded daily can be in the hundreds of millions for a sub-penny stock. Legitimate information on penny stock companies can be difficult to find and a stock can be easily manipulated.
