The five mistakes that cost new PSX investors the most
Not the obvious ones. These are the errors that look reasonable at the time and are only visible in hindsight.
Every one of these is a mistake made by someone sensible, acting in good faith, with real money. None of them look foolish in the moment. That is exactly what makes them expensive.
1. Acting on a tip you cannot evaluate
Someone in a WhatsApp group says a stock is about to move. Sometimes they are right, which is the problem, the occasional win teaches you to keep listening.
The structural issue is not accuracy. It is that a tip gives you an entry and nothing else. You do not know why to hold, when to sell, or what would mean the thesis has broken, because you never had a thesis. And the person who gave you the tip bears none of the loss.
The test: can you explain, in two sentences, why this company is worth owning? If not, you are not investing. You are relaying a message.
2. Putting money in that you will need soon
Equity investing needs time to work, and it needs you to be able to sit through drawdowns without selling. Money earmarked for a wedding, a tuition payment, or a medical fund cannot do that, because the market does not consult your calendar.
Before any of it goes into shares: an emergency fund covering several months of expenses, held in cash. It feels like an unproductive use of money. It is what makes the rest of the portfolio survivable.
3. Concentrating everything in one or two names
New investors often hold two or three stocks, usually in the same sector, usually because those were the names they had heard of. The upside feels good. The downside is that a single company-specific event (a regulatory change, a bad quarter, a governance failure) can take a large share of your savings with it.
Diversification does not require dozens of holdings. It requires that no single position can do disproportionate damage, and that your holdings are not all exposed to the same underlying risk.
4. Selling the good position and holding the bad one
This is one of the most consistently documented patterns in investor behaviour: people realise gains quickly and hold losses indefinitely, because selling at a loss means admitting the decision was wrong.
The market has no memory of what you paid. The only question that matters is whether you would buy this company today at this price. If the answer is no, your purchase price is not a reason to keep holding.
5. Checking prices every day
It feels like diligence. It functions as a source of noise. Daily price movement in an individual stock is mostly random with respect to anything you care about over a five-year horizon, and watching it closely reliably produces the urge to act.
If your thesis is measured in years, review on a schedule, quarterly, when results are published, or when something specific changes about the business. Not continuously.
What connects all five
Every one of these is a decision made without a framework. The tip, the timeline mismatch, the concentration, the asymmetric selling, the constant checking, each is what happens when there is no pre-existing rule, so the decision gets made by whatever you happen to be feeling.
Building that framework is learnable, and it is most of what we teach.
