Most of the time we regret buying something when we see the price drop. Then we don't have any more dollars to buy. But if we divide our total dollars into three or four parts and buy slowly at each down, then the chances of profit are high. And if we get profit after buying first, then we will sell. For this reason, I think it is better to invest little by little instead of investing all the dollars at once. What is your opinion?
You are absolutely correct and this has been the strategy of the whales and big institutions. They don't buy at once, they keep buying gradually whether the price of the assets they are accumulating is going up or dip. This is necessary to buy at different prices so that the average price will be lower at random.
This is a typical DCA strategy that implies buying at different intervals by splitting the investment funds into different part in order to price at different price which will become profitable at the end. This same applies to trading for those have us that likes buying at different prices as price keep following our initial long or short direction.
It is not too late to adhere to the kind of buying it trading strategy which is very effective when a trader or investor follows strict risk management. For anyone to be successful at in trading, they must be able to follow a reliable strategy without being greedy.
