Try to establish the value of a company.

Each year we buy stocks and they go up, we sell them and then we try to buy something cheaper.

Price is the most important factor to use in relation to value.

Don't be in too much of a hurry to sell.

Have a philosophy of investment and try to follow it.

Basically, we try to buy value expressed in the differential between its price and what we think its worth.

You know, people tend to like to buy companies that are doing well.
