Learning when to “sell”

I learned some time ago that it is more difficult to define when to sell than when to buy.

Now during the learning process about trading I learned a couple of tips. Both of them are basic and valid for long term investment.

• Check the average of 200 days and when the value of the stock suddenly grows provoking an increase in the distance with respect the 200 days average, then it can be a good moment to sell.
• Analyse the fundamentals and check if the value is expensive.

For sure, both checks can be combined.
