Basic 12 methods to know before investing on shares

hi

some methods for an investor to know while investing on shares

1. Buy low-sell high. As simple as this concept appears to be, the vast majority of investors do the exact opposite. Your ability to consistently buy low and sell high, will determine the success, or failure, of your investments. Your rate of return is determined 100% by when you enter the stock market.

2. The stock market is always right and price is the only reality in trading. If you want to make money in any market, you need to mirror what the market is doing. If the market is going down and you are long, the market is right and you are wrong. If the stock market is going up and you are short, the market is right and you are wrong.

Other things being equal, the longer you stay right with the stock market, the more money you will make. The longer you stay wrong with the stock market, the more money you will lose.

3. Every market or stock that goes up will go down and most markets or stocks that have gone down, will go up. The more extreme the move up or down, the more extreme the movement in the opposite direction once the trend changes. This is also known as "the trend always changes rule."

4. If you are looking for "reasons" that stocks or markets make large directional moves, you will probably never know for certain. Since we are dealing with perception of markets-not necessarily reality, you are wasting your time looking for the many reasons markets move.

A huge mistake most investors make is assuming that stock markets are rational or that they are capable of ascertaining why markets do anything. To make a profit trading, it is only necessary to know that markets are moving - not why they are moving. Stock market winners only care about direction and duration, while market losers are obsessed with the whys.

5. Stock markets generally move in advance of news or supportive fundamentals - sometimes months in advance. If you wait to invest until it is totally clear to you why a stock or a market is moving, you have to assume that others have done the same thing and you may be too late.

You need to get positioned before the largest directional trend move takes place. The market reaction to good or bad news in a bull market will be positive more often than not. The market reaction to good or bad news in a bear market will be negative more often than not.

6. The trend is your friend. Since the trend is the basis of all profit, we need long term trends to make sizeable money. The key is to know when to get aboard a trend and stick with it for a long period of time to maximize profits. Contrary to the short term perspective of most investors today, all the big money is made by catching large market moves - not by day trading or short term stock investing.

7. You must let your profits run and cut your losses quickly if you are to have any chance of being successful. Trading discipline is not a sufficient condition to make money in the markets, but it is a necessary condition. If you do not practice highly disciplined trading, you will not make money over the long term. This is a stock trading “system” in itself.

8. The Efficient Market Hypothesis is fallacious and is actually a derivative of the perfect competition model of capitalism. The Efficient Market Hypothesis at root shares many of the same false premises as the perfect competition paradigm as described by a well known economist.

The perfect competition model is not based on anything that exists on this earth. Consistently profitable professional traders simply have better information - and they act on it. Most non-professionals trade strictly on emotion, and lose much more money than they earn.

The combination of superior information for some investors and the usual panic as losses mount caused by buying high and selling low for others, creates inefficient markets.

9. Traditional technical and fundamental analysis alone may not enable you to consistently make money in the markets. Successful market timing is possible but not with the tools of analysis that most people employ.

If you eliminate optimization, data mining, subjectivism, and other such statistical tricks and data manipulation, most trading ideas are losers.

10. Never trust the advice and/or ideas of trading software vendors, stock trading system sellers, market commentators, financial analysts, brokers, newsletter publishers, trading authors, etc., unless they trade their own money and have traded successfully for years.

Note those that have traded successfully over very long periods of time are very few in number. Keep in mind that Wall Street and other financial firms make money by selling you something - not instilling wisdom in you. You should make your own trading decisions based on a rational analysis of all the facts.

11. The worst thing an investor can do is take a large loss on their position or portfolio. Market timing can help avert this much too common experience.

You can avoid making that huge mistake by avoiding buying things when they are high. It should be obvious that you should only buy when stocks are low and only sell when stocks are high.

Since your starting point is critical in determining your total return, if you buy low, your long term investment results are irrefutably better than someone that bought high.

12. The most successful investing methods should take most individuals no more than four or five hours per week.

Some facts to note while placing share order

hi

there are some facts to consider while placing your orders to buy shares
some are :

• Security - All orders must indicate the security being ordered. Securities are defined by a unique ASX code.
  
• Quantity of Securities - Each order must specify a quantity of the security to be bought or sold. Depending upon the value of the order, the quantity may or may not be disclosed.
  
• Price - An order must have a price. The way a price is expressed depends upon the security being ordered, ie shares, warrants, company options etc.
  
• Types of orders - The order type helps determine how the order trades and the price it may trade at.
  
• Crossings - Brokers must follow procedures when acting on behalf of both the buyer and the seller in a transaction.
  
• Life of an order - An order may be given an expiry date when it is placed, or it may be given a default expiry. In addition, certain market events will cause an order to be automatically cancelled prior to its expiry date.
  
• Other Considerations - The decision to buy or sell should take into consideration factors other than the security and its price. Trade prices may be affected by the current market phase, upcoming dividends and so on.

hence while u try to place an order .. consider these essential factors !!

Leverages Strategies

Stock that a trader does not actually own may be traded using short selling, margin buying may be used to purchase stock with borrowed funds; or, derivatives may be used to control large blocks of stocks for a much smaller amount of money than would be required by outright purchase or sale.


Short selling
In short selling, the trader borrows stock (usually from his brokerage which holds its clients' shares or its own shares on account to lend to short sellers) then sells it on the market, hoping for the price to fall. The trader eventually buys back the stock, making money if the price fell in the meantime or losing money if it rose. Exiting a short position by buying back the stock is called "covering a short position." This strategy may also be used by unscrupulous traders to artificially lower the price of a stock. Hence most markets either prevent short selling or place restrictions on when and how a short sale can occur. The practice of naked shorting is illegal in most (but not all) stock markets.


Margin buying
In margin buying, the trader borrows money (at interest) to buy a stock and hopes for it to rise. Most industrialized countries have regulations that require that if the borrowing is based on collateral from other stocks the trader owns outright, it can be a maximum of a certain percentage of those other stocks' value. In the United States, the margin requirements have been 50% for many years (that is, if you want to make a $1000 investment, you need to put up $500, and there is often a maintenance margin below the $500). A margin call is made if the total value of the investor's account cannot support the loss of the trade. (Upon a decline in the value of the margined securities additional funds may be required to maintain the account's equity, and with or without notice the margined security or any others within the account may be sold by the brokerage to protect its loan position. The investor is responsible for any shortfall following such forced sales.) Regulation of margin requirements (by the Federal Reserve) was implemented after the Crash of 1929. Before that, speculators typically only needed to put up as little as 10 percent (or even less) of the total investment represented by the stocks purchased. Other rules may include the prohibition of free-riding: putting in an order to buy stocks without paying initially (there is normally a three-day grace period for delivery of the stock), but then selling them (before the three-days are up) and using part of the proceeds to make the original payment (assuming that the value of the stocks has not declined in the interim).
