$29 for Five Online Stock-Trading Courses from Lex van Dam Trading Academy ($630 Value)

The bell became the preferred way to signal Wall Street’s opening after using a truck’s air horn resulted in traders passing in front of the podium, pumping their arms up and down in an effort to get the horn blown again. Fine-tune your financial signals with today’s Groupon: for $29, you get five online stock-trading courses from Lex van Dam Trading Academy (a $630 value).

A professional hedge-fund manager and one-time trader with Goldman Sachs, Lex van Dam opened a trading academy to teach Main Street folks of all skill levels to turn a profit in the stock market. The online academy organizes material into five 40-minute modules based on the basic principles of successful trading, including chart analysis and risk management. Aspiring marketeers learn to make savvy trades based on a deep understanding of the market, rather than from newspaper predictions or company horoscopes. Company-evaluation modules reveal which financial numbers matter and which are irrelevant, and trading psychology teaches students to make smart trades without letting emotions sway them. Groupon-holders can watch each module up to five times, ultimately gaining enough insight to potentially design strong personal portfolios. Lex van Dam taught several novices to out-trade pros on BBC’s Million Dollar Traders, a reality show that turned ordinary people into profitable market wizards and insufferably smug Monopoly players.
