Most of us get that bit wiser after an event that causes us to lose money, such as falling for an online scam. Chances are we would never fall for a similar ruse again: Once bitten, twice shy, as the saying goes.

But this rule apparently does not apply to many investors, who prefer to believe that tomorrow will always be better. Otherwise, how do you explain why we keep seeing the same reckless behaviour of folks who try to win in the stock market in the hopes of making it big in every downturn?

And worse, some people actually jump into the stock market with money borrowed on their credit cards. So before you leap back into the game, it pays to be grounded with evergreen investment tips that may save you from financial ruin.

The reason is simple – you can never beat the people who are close to the game. Just take the wild swings of Tesla stocks in recent years, which is probably one of the most watched counters for younger investors.

Although the sales of Tesla EVs had dropped in many countries in 2024, many investors were taken by surprise when the stock sky-rocketed to record value because its largest shareholder Elon Musk was a close ally to the then winning presidential candidate Donald Trump. Just as dramatic was how the price plummeted months later, all because the two had a very public fallout.

What this means is that if you think a certain stock has good potential, just stick with it for the longer term and not be tempted to buy or sell based on the price swings.

Unless you have found a crystal ball that lets you peek into the future, all investments come with risk. For instance, no one can predict how the current global turmoil will pan out in the coming months. So if you invest all your spare cash or, even worse, invest using loans, you can find yourself in dire straits when things turn bad.

Even if you can spare $100,000 or even millions, it is better to not invest all at one go but spread it out in tranches. You should be very conservative when it comes to investing your hard-earned salary. But if your investment has turned in a profit, you can consider taking more risks with the profit because losing a windfall is less painful than losing your own money.

The worst thing you can do is to invest based on tips from friends of a friend. Due to the fear of losing out, some people will just buy into a “hot” stock even though they have no clue what the company does.

Then there are those who are very confident because they follow the investment styles of legendary investors who have become billionaires due to their astute skills. While there is nothing wrong in trying to learn from the best, you must realise that the chance of achieving similar success is almost zero unless you have unlimited cash at your disposal.

An investor with $10 billion can still bounce back with the last billion even if he loses 90 per cent of his wealth. That’s why they can afford to invest when the rest of us are scared stiff.

Ask yourself this: Were you busy buying up all the rock-bottom bank stocks during the 2008 financial crisis, or more recently, stocks of oil companies after war broke out in Iran?

With perfect hindsight, many wished they had, but the reality was they had no money to do so then.

Some investors tend to get overly sentimental after they hold certain stocks for years. And even when the outlook for the share dips, they refuse to let go, hoping that it will eventually recover its glory days. Even worse, some shareholders view themselves as loyal customers who will continue to support the company come what may.

The reality is that the management won’t even know you have bought its shares unless you show up and shake the boss’s hand at the annual general meeting.

Even so, unlike customers who have the right to demand refunds for bad deals, investors won’t get any compensation for stock losses because they are deemed to be “owners” of the company, albeit small ones. So if you think it is prudent to cut your losses by selling the stock, do it and get some of your money back.

Many people seem to think that a long-term investment means buying a stock or fund, keeping it for years and then all will be fine. This may be true for some resilient investments, but it does not mean you can take your eye off all your long-term investments.

Otherwise, you may wake up one day to find that your portfolio has become worthless simply because the companies have run into financial troubles. This is especially true now because many firms are facing the twin threats of global uncertainty as well as disruption by technology. If you don’t have time to monitor your portfolio, you should stick to less risky products such as government bonds and mark the maturity dates in your calendar.

You are unlikely to walk into a tour agency, hand over $10,000 and tell the operator to sign you up for a mystery trip. If you won’t buy something without knowing what it is, you should also never invest in something you don’t really understand.

For instance, you should remind all the seniors in your households that if all they want is to put their money in fixed deposits, they must never sign up for anything that offers higher rates, no matter how attractive it seems, especially if they do not understand how it works.

Finally, know that money won’t just fall out of the sky without you putting in time and effort. So it pays to invest in improving your knowledge first so that you can make informed decisions and bets.
