How to Take Over a Company by Buying Its Stock

Obtain the company's most recent quarterly balance sheet. The company's ownership structure is outlined in the section of the balance sheet entitled stockholders' equity.
Determine the number of shares outstanding. This is a line item in stockholders' equity. It tells you how many units of stocks have been issued. For instance, let's say that company XYZ has 100,000 shares outstanding.
Calculate the number of shares you need to purchase in order to take over the company. Multiply the total number of shares outstanding by .51. In this example the answer is .51 multiplied by 100,000, or 51,000.
Calculate the amount of capital you need to raise in order to purchase a 51 percent stake in the company. Determine the current price of company stock by contacting your stockbroker, the company's investor relations department or by doing your own research. Let's say the current share price is $10. In this example, the total capital needed in order to purchase a 51 percent stake in the company is 51,000 multiplied by $10, or $510,000.
Secure capital. If you don't have the full stake, you can request a bank loan or solicit the help of other investors. As leverage or collateral, look at the current cash position of the company -- the first line item on the balance sheet. This amount can be used to pay off any loans once the company is taken over.
Purchase a 51 percent stake in the company. Contact your stockbroker to do this. She will execute the order in waves in order to minimize the increase in stock price as the stock is being purchased.

How to Invest Wisely in Penny Stocks

Use caution when investing in penny stocks. These stocks are like after dinner mints. They complement the regular investment but never make up the entire meal. Don't invest all your money into one stock.
Investigate the company. Sometimes the company is a start-up one with a great idea. See how long the CEO has been in the industry. See if he was a CEO of other companies. When you invest in penny stocks, both the product and the people are important.
Investigate the history of the price. When you invest in penny stocks, you might see movement that encourages a buy or tells you to be cautious. It takes very little growth to show a huge increase by percent. Be aware that someone may control the price by buying or selling shares and make it seem more, or less, attractive.
Use the information if you see a pattern in the penny stock price movement. Create a limit order for both buy and sell. Put the buy limit at the lower end of the price cycle and wait until you purchase the stock at that price. Then use a limit order for the top price you want to sell the stock and when it reaches that price it automatically sells. When you invest in penny stocks sometimes you make money with the cycle of buying and selling. This may take weeks.
Hang on to the stock if you hear of new innovations at the company. Purchase for long-term investments, regardless of the day to day movement. If you invest in a penny stock, don't sell just because the price went up if you believe the product has a future. Make it a long-term hold.
Track any events that may make your stock more valuable. For example, if oil prices go up, an ethanol company has a better chance of success.
Expect to lose your money. Penny stock is a gamble and only use money not involved in important goals. Really low priced penny stocks are fun to play with but also potentials for loss. Keep this in mind before you invest in penny stocks.
