How to build your first PSX portfolio

Most first portfolios are not built. They accumulate, a stock someone mentioned, another from an article, a third because it fell and looked cheap. Six months later there is a collection of positions with no relationship to each other and no stated purpose.

A portfolio is a set of decisions that fit together. Here is how to construct one deliberately.

Before the first rupee goes in

Three things must be true. None of them involve stocks.

1. You have an emergency fund of three to six months of expenses, in cash, that you will not touch for this.
2. You have no high-interest short-term debt outstanding. Paying that down is a guaranteed return; the market offers no such thing.
3. The money you are investing is money you will not need for at least three to five years.

If any of these is not true, the honest answer is that you are not ready yet, and starting anyway is how people end up selling at the worst possible moment.

How many holdings

For a first portfolio, somewhere between eight and fifteen is a sensible range.

Fewer than about eight and a single company-specific event (a governance failure, a regulatory change, a bad quarter) can do damage that takes years to recover. More than about fifteen and you cannot realistically follow them all, which means you own things you no longer understand.

Start at the lower end and add as you learn. It is easier to add a holding than to unwind an over-diversified portfolio you never had time to research.

Sizing positions

The simplest approach, and a perfectly good one to begin with, is roughly equal weighting. Ten holdings, about 10% each. It requires no forecasting skill and it prevents the most common beginner error, one enormous position that determines your entire outcome.

A worked example with PKR 500,000:

• Ten holdings at roughly PKR 50,000 each.
• No single position above PKR 75,000, even after it rises, trim back when it drifts well past its target weight.
• No sector above about 30% of the total, which for most people means no more than three holdings from any one sector.

What goes in first

Not the most exciting company. The most understandable one.

For a first holding, look for a business you can explain in two sentences, that has been profitable across several years including bad ones, that pays a dividend it can actually afford, that carries manageable debt, and that trades with enough daily volume that you could sell it without difficulty.

Those criteria will exclude most of what gets talked about in WhatsApp groups. That is a feature.

Spread the entry over time

Do not deploy the whole amount on one day. Not because timing the market is impossible (though it is) but because entering gradually limits the damage of starting at an unlucky moment, and it gives you time to notice how you actually feel when a position falls.

Investing a fixed amount at regular intervals over six to twelve months is a reasonable structure for a first portfolio.

Write it down

For every holding, record before you buy: why you are buying it, what you expect it to do, what would tell you the thesis is broken, and what weight it should hold.

This document is the portfolio. The shares are just its current expression. When a position falls 20%, the note is what lets you distinguish "the market is being irrational" from "I was wrong", a distinction that is almost impossible to make honestly in the moment without it.

Reviewing

Quarterly, or when results are published. Not daily.

At each review, ask three questions of each holding: has anything changed about the business, is the position still near its target weight, and would I buy this today at this price? The third question is the one that does the work.
