This is one of the Golden Rules from Bursa Malaysia teaching people how to trade Malaysia stock market.
This is the topic content and my highlight in RED.
The Malaysian stock market is one of the strongest and sometimes most dynamic markets in the world.
While the market has always recovered from falls, the same cannot be said for individual companies. Even during a booming market, some companies can suffer significant losses.
Trade only on an uptrend and sell the poor performers, this will make it impossible to experience a large loss. This is the secret to outperforming the market and achieving a consistently superior return.
Undertake some research on the Bursa Malaysia or in a local investment paper. List three shares that have showed decreased performance recently and three shares that have showed increased performance recently.
Did you get that ? "IMPOSSIBLE to LOSE A LOT" !! What a way to set GOAL in stock investment !! Furthermore, making MANY small loses is as bad as making ONE big lost. As a matter of fact, many small loses may actually be worse because you didn't feel the pain and didn't realize how much you have lost. As in Boiling Frog story.
Compares that with the Number 1 TOP stock investor in the world ...
What they should have said is to Employ A proper Stop Loss Strategy. Aim to be right and learn until you make more correct decisions, that is what the game is all about. But just in case you are wrong, preserve your capital allowing you to 'COME BACK' by adopting a stop loss strategy. When investing in a fundamentally strong business, it takes patience and sometimes ignorance to just buy and hold.
Why does even Bursa make such a bias education ? Well, buffett has said it above. Bursa needs brokers, brokers need money, so Bursa also wants you to buy and sell as much as possible so that you pay them more transaction fees.
Sell it ! Don't Hold ! Else Bursa will DIE !!
Ya right ! You may just as well donate your money to Bursa ....
