Newbies are actually the most needed persons to execute risk management as they are more prone to losses the moment they start entering the market without prior knowledge and experiences. The fact that it’s hard to make money and be profitable in your investment, then newbies should be more aware about that so that they will learn to be extra careful when doing such risks. And while risks are inevitable when trading or investing, but those newbies who prefer to study the market first and gain sufficient learning are actually lessening the risk that they have to undergo.
Risk management is necessary not for newbies only but also for those experienced traders, But the issue here with newbie traders is that most of them are reluctant to learn the basic tools meant to help traders especially inexperienced ones to limit losses, they are only focused on the profit side while leaving their account unprotected, which is why you see some of them come asking how to put stop losses and limit orders after they must have gotten raked by the market, they now started running to learn about those stuff at last which were meant to be the first thing they should have done.
