Warren Buffett is widely considered one of the greatest investors of
 all time, but if you were to ask him whom he thinks is the greatest 
investor, he would probably mention one man: his teacher, 
Benjamin Graham. Graham was an investor and investing mentor who is generally considered the 
father of security analysis and 
value investing. 
His
 ideas and methods on investing are well documented in his books, 
"Security Analysis" (1934), and "The Intelligent Investor" (1949), which
 are two of the most famous investing texts. These texts are often 
considered requisite reading material for any investor, but they aren't 
easy reads. In this article, we'll condense Graham's main investing 
principles and give you a head start on understanding his winning 
philosophy. 
Principle #1: Always Invest with a Margin of SafetyMargin of safety is the principle of buying a security at a significant discount to its 
intrinsic value,
 which is thought to not only provide high-return opportunities, but 
also to minimize the downside risk of an investment. In simple terms, 
Graham's goal was to buy assets worth $1 for 50 cents. He did this very,
 very well. 
 
 
     

 
    
 
    To Graham, these business assets may have been valuable because of 
their stable earning power or simply because of their liquid cash value.
 It wasn't uncommon, for example, for Graham to invest in stocks where 
the 
liquid assets on the balance sheet (net of all debt) were worth more than the total 
market cap
 of the company (also known as "net nets" to Graham followers). This 
means that Graham was effectively buying businesses for nothing. While 
he had a number of other strategies, this was the typical investment 
strategy for Graham. 
This concept is very important for 
investors to note, as value investing can provide substantial profits 
once the market inevitably re-evaluates the stock and ups its price to 
fair value.
 It also provides protection on the downside if things don't work out as
 planned and the business falters. The safety net of buying an 
underlying business for much less than it is worth was the central theme
 of Graham's success. When chosen carefully, Graham found that a further
 decline in these undervalued stocks occurred infrequently. 
While many of Graham's students succeeded using their own strategies, they all shared the 
main idea of the "margin of safety." 
Principle #2: Expect Volatility and Profit from ItInvesting in stocks means dealing with 
volatility.
 Instead of running for the exits during times of market stress, the 
smart investor greets downturns as chances to find great investments. 
Graham illustrated this with the analogy of "Mr. Market," the imaginary 
business partner of each and every investor. Mr. Market offers investors
 a daily price quote at which he would either buy an investor out or 
sell his share of the business. Sometimes, he will be excited about the 
prospects for the business and quote a high price. Other times, he is 
depressed about the business's prospects and quotes a low price.
Because
 the stock market has these same emotions, the lesson here is that you 
shouldn't let Mr. Market's views dictate your own emotions, or worse, 
lead you in your investment decisions. Instead, you should form your own
 estimates of the business's value based on a sound and rational 
examination of the facts. Furthermore, you should only buy when the 
price offered makes sense and sell when the price becomes too high. Put 
another way, the market 
will fluctuate - sometimes wildly - but
 rather than fearing volatility, use it to your advantage to get 
bargains in the market or to sell out when your holdings become way 
overvalued.
 
    Here are two strategies that Graham suggested to help mitigate the negative effects of market volatility:
Dollar-Cost Averaging Dollar-cost averaging
 is achieved by buying equal dollar amounts of investments at regular 
intervals. It takes advantage of dips in the price and means that an 
investor doesn't have to be concerned about buying his or her entire 
position at the top of the market. Dollar-cost averaging is ideal for 
passive investors and alleviates them of the responsibility of choosing 
when and at what price to buy their positions.

Investing in Stocks and Bonds Graham recommended distributing one's portfolio evenly between 
stocks and 
bonds
 as a way to preserve capital in market downturns while still achieving 
growth of capital through bond income. Remember, Graham's philosophy 
was, first and foremost, to preserve capital, and 
then to try 
to make it grow. He suggested having 25-75% of your investments in 
bonds, and varying this based on market conditions. This strategy had 
the added advantage of keeping investors from boredom, which leads to 
the temptation to participate in unprofitable trading (i.e. 
speculating). 
Principle #3: Know What Kind of Investor You Are Graham
 advised that investors know their investment selves. To illustrate 
this, he made clear distinctions among various groups operating in the 
stock market.
Active Vs. PassiveGraham referred to 
active and 
passive investors as "enterprising investors" and "defensive investors."
You
 only have two real choices: The first choice is to make a serious 
commitment in time and energy to become a good investor who equates the 
quality and amount of hands-on research with the expected return. If 
this isn't your cup of tea, then be content to get a passive ( possibly 
lower) return but with much less time and work. Graham turned the 
academic notion of "risk = return" on its head. For him, "Work = 
Return." The more work you put into your investments, the higher your 
return should be.    
 
    If you have neither the time nor the inclination to do quality research on your investments, then investing in an 
index
 is a good alternative. Graham said that the defensive investor could 
get an average return by simply buying the 30 stocks of the 
Dow Jones Industrial Average in equal amounts. Both Graham and Buffett said that getting even an average return - for example, equaling the return of the 
S&P 500
 - is more of an accomplishment than it might seem. The fallacy that 
many people buy into, according to Graham, is that if it's so easy to 
get an average return with little or no work (through indexing), then 
just a little more work should yield a slightly higher return. The 
reality is that most people who try this end up doing much worse than 
average. 
In modern terms, the defensive investor would be 
an investor in index funds
 of both stocks and bonds. In essence, they own the entire market, 
benefiting from the areas that perform the best without trying to 
predict those areas ahead of time. In doing so, an investor is virtually
 guaranteed the market's return and avoids doing worse than average by 
just letting the stock market's overall results dictate long-term 
returns. According to Graham, beating the market is much easier said 
than done, and many investors still find they don't beat the market. 
Speculator Vs. InvestorNot
 all people in the stock market are investors. Graham believed that it 
was critical for people to determine whether they were investors or 
speculators.
 The difference is simple: an investor looks at a stock as part of a 
business and the stockholder as the owner of the business, while the 
speculator views himself as playing with expensive pieces of paper, with
 no 
intrinsic value.
 For the speculator, value is only determined by what someone will pay 
for the asset. To paraphrase Graham, there is intelligent speculating as
 well as intelligent investing - just be sure you understand which you 
are good at.
The Bottom LineGraham served as
 the first great teacher of the investment discipline and his basic 
ideas are timeless and essential for long-term success. He bought into 
the notion of buying stocks based on the underlying value of a business 
and turned it into a science at a time when almost all investors viewed 
stocks as speculative. If you want to improve your investing skills, it 
doesn't hurt to learn from the best. Graham continues to prove his worth
 through his disciples, such as Warren Buffett, who have made a habit of
 beating the market.
