Can You Time the Stock Market? Why Waiting for the Perfect Price Rarely Works

Waiting for a lower share price can help if it falls, but you may miss a rise that never reverses. The difficulty is knowing which will happen before you decide.

What market timing means

Market timing is the attempt to buy at the lowest price and sell at the highest. It includes waiting for a dip, selling before a fall you expect, and moving in and out as prices change.

Why it is so hard

Moving out of shares and back in requires two decisions at the right times. Other people may act on a headline before you see it. A price can also sit still for weeks and then jump in a day, leaving someone who was waiting for a dip behind.

In a thin market, one large order can move the price without any change in the company's business. Acting on each swing can mean trading on noise. While you wait, money outside the shares receives none of that company's profits or dividends.

The cost of waiting

Worked example · invented prices

A share is priced at 100 birr and you have 10,000 birr. You could buy now, or wait for the price to fall to 90 first. Here are two things that could happen next.

What happens next	Buy now at 100	Wait for 90
The price rises to 120 and never touches 90	100 shares worth 12,000 birr, a gain of 2,000	Still holding 10,000 birr in cash, a gain of 0
The price falls to 90, then rises to 105	100 shares worth 10,500 birr, a gain of 500	About 111 shares bought at 90, worth about 11,667 birr, a gain of about 1,667

Waiting wins in the second case and loses in the first. You cannot know in advance which will happen. Now suppose you buy at 100, sell in a scare when the price hits 90, and the price then recovers to 105. You sell 100 shares for 9,000 birr. Holding them would have been worth 10,500 birr, so selling left you 1,500 birr behind, before fees.

Costs make this worse. One broker was reported in the press in June 2025 to charge a commission of 1.6 percent on each trade. At that rate, selling 9,000 birr of shares and buying them back could cost around 288 birr in commission alone, before the spread. Frequent trades repeat those costs. Check your own provider's current fees, because this figure is only an example.

What timing looks like in real life

You might wait for a dip and miss a rise, or sell "before the crash" and buy back at a higher price. Checking prices every day makes small moves feel urgent. Buying after a jump for fear of missing out and selling after a fall for fear of more losses are versions of the same problem. Be wary of people who claim to know where prices are going. You tend to hear from those who guessed right rather than those who guessed wrong, a pattern called survivorship bias.

Time horizon matters more than timing

Someone who can leave money invested for years has less reason to focus on a particular week. Money needed next month should not depend on the share price then. Ask when you will need the money before deciding whether shares fit.

What to do instead

Decide what the money is for, when you will need it and how much you can leave untouched. Then judge the share price against the company's value. Our guide to analyzing an Ethiopian bank shows one way. A limit order lets you set a price you are willing to pay without chasing a jump. Decide in advance what would make you sell, and review the holding on a schedule rather than after every move.

Paying a fair price matters. The company's numbers can help you judge whether today's price is reasonable, even though they cannot reliably tell you where it will go next.
