black friday

Black Friday is the day after American Thanksgiving when shops slash prices, but in investing circles it also nods to sudden, sharp market sell offs.

Why would anyone call a shopping day and a stock market crash by the same name? It sounds like a coincidence, but it is not really. Both share one thing at their core, a sudden rush of activity that catches people off guard, whether that rush is towards the shops or away from a falling market.

In everyday life, Black Friday is the Friday after American Thanksgiving, when shops in the United States and increasingly in the United Kingdom offer huge discounts. If you have relatives in the diaspora, you have probably seen them send screenshots of laptops or trainers going for half price, and asked them to grab one for you back home too.

In investing, though, the term carries an older, heavier meaning. It refers to specific days in market history when prices fell hard and fast, often triggering panic. The original one was in 1869, when gold prices in America collapsed in a single day and ruined a lot of speculators. Since then, people casually use the phrase for any dramatic single day crash, though it is more of a nickname than a technical term you will find in a textbook.

Here is where it gets interesting for a Nigerian investor. The Nigerian Exchange has had its own rough days, sudden drops driven by fear after a policy announcement or a global shock, even if nobody stamped the name Black Friday on them locally. The lesson from every Black Friday, shopping or crashing, is the same. Crowds move fast, and if you are not paying attention, you either miss the bargain or get caught in the stampede.

So when someone mentions Black Friday, ask which one they mean before you react. One might save you money on a phone. The other is a reminder to keep a level head when everyone else is running.

In November, a Nigerian based in London buys a discounted television during Black Friday sales and ships it home. Months later, a sudden global oil price shock causes a one day sell off on several exchanges, and traders jokingly call it another Black Friday, even though it has nothing to do with shopping.

Questions people ask

Is Black Friday an official stock market term?

Not really. It is a nickname people use for sudden, sharp market crashes, not a formal term you will find in financial regulations or textbooks.

Did Nigeria ever have a market crash called Black Friday?

There is no widely recorded local event officially named that, but the Nigerian Exchange has had sudden, sharp one day drops, usually linked to policy news or global shocks, that fit the same spirit.

Should I invest during Black Friday shopping sales?

Black Friday shopping discounts are about spending, not investing. If you want to put money to work, it is wiser to stick to your investment plan rather than get caught up in sale day excitement.
