I first got exposed to the stock market investing back in 2015 through like-minded university friends and investment books. However, without proper guidance and experience with the market, I made tons of mistakes in my early investment journey.

Looking back, while it did not feel good at all to lose money during that time, I am glad that I’ve made those mistakes because it was those experiences that shaped me into a more diligent and careful investor today.

Here are 5 mistakes that I’ve committed, some of which are extremely common among experienced and new investors alike:


(1) Making investment decisions based on ‘Hot Tips’ and ‘Analyst Recommendations’

One of the regrettable mistakes that I’ve made in my early investing journey was to rely on ‘Hot Tips’ and ‘Analyst Recommendations’ that were shared with me.

I remembered putting a few hundred bucks into a local stock and ended getting out at a lost just because of a ‘Hot Tips’ from my friend which went like this:

“The boss of the company is very confident that they will do great for the next quarter onwards.”

Dumb me, dumb me.

Depending solely on ‘Analyst Recommendations’ is also extremely dangerous. While you may make money on some ideas, you may also lose a substantial amount in it. The bottom line is, you would never really know the reason of you winning or losing as you’ve not done the necessary due diligence yourself – thus lack the understanding towards the particular company or industry.


Key lesson: Always take ‘Hot Tips’ and ‘Analysts Recommendations’ in with a pinch of salt. Even if those insights are true, they would probably have gotten through multiple parties before it reaches you – the final victim of the market.

(2) Invest based on Gut Feeling & Impulse without Sufficient Research

Investing based on gut feeling and impulse is another mistake that I have done in my early investing journey. (Confession: I still make this mistake every now and then).

One of my vivid memory of buying on impulse was when my friend was participating in a case study competition and got Inari (a local semiconductor company that works with Apple) to research. As such, I’ve always heard about the company from my friend and hence developed a positive interest towards Inari.

With the very limited information that I got from my friend, I started to formulate my own theory:

“After all, if iPhone sales have (had) been doing so good, Inari should be a great buy, right?”

And you can have a smart guess on my investment outcome.  


Key lesson: Refrain from investing based on feelings and limited knowledge. If you wouldn’t risk your health by buying a packet food without first checking its expiry date, why gamble your hard-earned savings or money purely on your feelings and limited knowledge?

(3) Too Afraid to Cut Losses and Taking Profit too Early

Now, I see this not just in myself, but also among many friends that invest as well.

Some of the biggest frustrations in my early investing journey was NOT so much on deciding WHAT company to buy (I already had ‘Hot Tips’ and ‘Analyst Recommendation’ for that), but rather WHEN to SELL my positions.

With no prior investing experience in the market, I tend to be extremely emotional regardless if price rises or drops.

Reason being, when the price drops, I would be too afraid to cut my losses in hope for a rebound (even worse, some inexperienced investors add-on to their positions while prices are dropping to ‘average’ down their losses).

On the other hand, when price rises, I also have the tendency to sell at little profit in fear of the market reverses later. As a result, some of my profits were cut short when prices move straight up just after I sold my positions.


Key lesson: Understand your intention when you enter a position. Are you in for the long-term, medium-term or short-term? Then, set your target profit (TP) and stop loss (SL) accordingly. Most importantly, stick religiously to your TP and SL.

(4) Ego to be Right

Well, well. Look at that newbie that tries to brag about his first few winning streaks and try to predict where would the market move in the future.

Chances are, we were in the position of that newbie before. We felt extremely ‘syiok’ or pumped whenever we were right and our positions hit our targeted profit.

Then, we moved on to brag about how easy it is for us to make money from the market. Even worse, we denied every difference in opinion by others.

Not long after that, market trend changes, bringing our beginners luck to an end as well. Guess what? It hurts so much to be wrong.


Key Lesson: No one is right 100% of the time. No method or strategy will be victorious 100% of the time. Be humble, if not the market will humble you.


Be humble, or the market will humble you.

(5) Never keep track of my investment

When I first started to invest, the idea of keeping track of my investments never came to my mind. As a result, I kept making the same mistakes over and over again.

Not only that, without a clear record of my investments, I couldn’t even track my profits or losses back then.

Now that I think about it, keeping an investing journal is, in my opinion, the most important habit that every new investor must pick up in order to make it in this journey.


Key Lesson: Pick a notebook or journal (or excel), keep track of all your stock investments – the entry and exit price, mistakes and lessons. You may not see the benefits now, but you will soon be glad that you did it in the first place.
