screening
Screening means using a set of rules to filter a large list of stocks down to the few worth your attention, before you spend a kobo.
In plain English
"How do you even choose which shares to buy? There are like two hundred on the NGX alone." "I don't look at all two hundred. I screen them first." "Screen them like Nollywood auditions?" "Basically. I set my conditions, low debt, steady profit for five years, dividend paying, and anything that doesn't meet all three gets sent home before I even learn its name."
That conversation is screening in a nutshell. You are not trying to know everything about every company. You are building a filter that does the boring sorting for you, so your energy goes only to the shortlist.
A Nigerian investor tired of guessing might screen the NGX for companies with consistent profit growth, low debt to equity, and a dividend history longer than three years. That alone might cut two hundred names down to fifteen worth a proper look at their annual reports.
In the United Kingdom, someone building an ISA portfolio might screen the FTSE 100 for dividend yield above four percent and a payout ratio under seventy percent, avoiding firms that are paying shareholders with money they cannot really spare.
Screening also shows up in ethics and belief. Some investors screen out alcohol, gambling, or arms companies entirely, others screen specifically for environmental, social and governance strength. Either way, the principle is the same, decide your rules first, then let the list obey them.
A relative abroad sending money home to invest through a local broker can ask the broker to screen for stable, dividend paying names rather than whatever is trending on social media that week. It turns a vague instruction into a disciplined one.
An investor screens the NGX for stocks with debt to equity below 0.5, profit growth for four straight years, and dividend yield above 5%. Out of 160 listed companies, only 12 pass every filter, including one paying a consistent ₦2 dividend per share. Those 12 become the actual research list, not the full market.
Questions people ask
Is screening the same as doing full research?
No, screening is the first filter, the sieve that narrows two hundred companies down to a manageable shortlist. Full research, reading annual reports, checking management, comparing competitors, comes after, on the smaller list screening leaves you with.
What criteria should a beginner use to screen Nigerian stocks?
Simple ones work well at first, consistent profit over the last three to five years, manageable debt levels, and a history of paying dividends. You can add more detailed filters like return on equity once you are comfortable reading financial statements.
Can screening make me miss good companies?
Yes, sometimes, a strict filter might exclude a young company with huge potential but no long profit history yet. Screening is meant to save time, not replace judgement, so treat it as a starting point rather than the final word.
