What could we learn from Warren Buffett?

Recently, I have read 2 books on Warren Buffett, the famous value
investor and 2nd richest person.  I would like to share with you 2 points which I learned
from his investing philosophy.

1) Buffett is very good at picking stocks and aiming to hold them for 5-10 years or even
for life.  He classifies all the companies into 2 types:

A - Commodity type business - in the long run most companies fell into this category.
The typical example is oil companies.  We buy oil simply look at their prices and seldom
bother which brand we use.  Because of competition, these companies are unable to
sustain a high profit margin.

B - Consumer monopoly, toll bridge, or franchise type of business - The most typical one
is Coca Cola.  When we are thirsty, most people in the world will think of Coke.  In
supermarkets, convenient stores or fast food restaurants, they can't afford without
carrying Coke, as it will certainly damage their business.  Because of its excellent
goodwill, Coke is able to determine its price and maintain a high profit margin.

For holding stocks for a very long term, we should narrow our choice into these kinds of
companies.

For example, Hutchison in the long term could maintain very good earnings because it
continues to have some kinds of monopoly power in different area:

Real estates - in the past years
Terminals
Mobile phone - Market leader in HK and I guess “Orange” is something unexpected.

The other example is HK Bank - it has the largest deposits in HK.  At least in the
previous years, it gives them a great advantage to sustain their profits ( I know nothing
about their business in UK).

Buffett’s portfolio is very limited.  In one year, he only holds five stocks.  The famous
ones are Coca Cola and the Washington Post.  He thinks the more you know about the
companies, the less risk you will bear.

2) His theory could not apply to all area of the price movement.  However he knows the
limitation of his theory.  He know he could not predict the daily price change which is
mostly affected by the investors behavior, instead of the company itself.  Therefore, he
set up his strategy by only looking at the earnings, growth and intrinsic value.  He only
cares about the market prices when the investors foolishly dump the prices far below the
intrinsic value.  He simply gives up those companies he doesn't understand or hard to
predict its future growth.  Therefore he did not buy Microsoft.   He doesn't trade very
often but patiently wait for the opportunity to come.  For Coca Cola and the Washington
Post, he has been holding for over 10 years and didn't make any single one trade.

Comparing to George Soros, I could not say who is right or who is wrong.  They are
simply going in a different approach.  The best thing is, we have to know what the
limitation is.  We should not expect a theory could explain all area of the price
movement, every day, every cycle or every year.  The most important thing is to make
money out of it.

For example,  in reviewing my use of moving averages, it is most profitable in the
significant imbalance of supply and demand, usually 2 or 3 times a year.  When the
market is trading in a narrow range, or relatively equilibrium between bulls and bears, I
will mostly lose money.  Therefore, it should sticks with those significant price change
periods.  In most of the other time, it would be better sit and watch.

Thanks for listening to me and hope it may stimulate a little bit thinking.
