Most people think markets move because of value. A company looks cheap, buyers rush in. A company looks expensive, sellers take profits. Simple. Except that’s not how markets actually behave day to day.
If valuation alone controlled markets, “cheap” shares would immediately bounce, “expensive” shares would immediately fall, and traders everywhere would make easy money. But we all know that’s not reality.
Sometimes a stock looks ridiculously cheap and keeps collapsing. Sometimes a stock looks wildly overpriced and keeps flying higher.
Why?
Because in the short term, markets are not driven by value. They are driven by liquidity.
Why do “cheap” stocks keep falling?
This is one of the most frustrating experiences in trading.
You find a stock that looks undervalued. The PE ratio looks attractive. Analysts say it’s cheap. Social media says it’s oversold. So you buy.
And then it drops another 10%.
We are seeing versions of this right now with Naspers and Prosus. On paper, many investors argue they already look cheap, yet the selling pressure continues.
The reason is simple. “Cheap” does not automatically create buyers.
This is where liquidity comes in. Liquidity simply means how easy it is for buyers and sellers to trade shares without causing a massive price move.
Think of it like this.
Imagine trying to sell a second-hand car. If 50 people are interested, you can probably sell it quickly at a fair price. But if nobody wants to buy, you keep dropping the price until someone finally steps in.
Markets work exactly the same way.
If there are more sellers than buyers, price falls. It doesn’t matter how “cheap” the stock looks.
That’s why traders often say, “The market can stay irrational longer than you can stay solvent.”
In the short term, supply and demand matter more than valuation.
The opposite also happens. Look at stocks like Nvidia or Palantir. Many investors have called them “too expensive” for months, yet they kept rallying because buyers kept flooding into the market faster than sellers could absorb them.
That’s liquidity in action.
For long-term investing, valuation is still critical. But for short-term trading, liquidity often matters more.
What actually creates liquidity in markets?
Liquidity is just money moving through the system.
Every day, massive players are constantly buying and selling:
• Hedge funds
• Pension funds
• Banks
• ETFs
• Institutions
• Retail traders
• Algorithms
And these players don’t all buy or sell for the same reason. Some are investing. Some are hedging risk. Some are forced to rebalance portfolios. Some are panic selling. Some are chasing momentum.
That constant flow of money is what moves markets every single day, irrespective of the reason.
When lots of buyers and sellers are active, markets feel smooth and stable. But when liquidity disappears, markets become dangerous.
This is why prices sometimes gap violently after:
• Interest rate decisions
• Earnings releases
• Economic data
• Political shocks
• Breaking news
Suddenly, everyone wants to sell at once and there aren’t enough buyers. That imbalance creates sharp price moves.
Professional traders understand this well.
They don’t just ask, “Is this stock cheap?”
They ask:
• Who is buying?
• Who is selling?
• Who is trapped?
• Where are stop losses sitting?
• Where could panic begin?
Because that’s what drives short-term price action.
How can traders use liquidity to their advantage?
Understanding liquidity helps traders stop fighting the market.
One of the biggest mistakes retail traders make is trying to predict where price “should” go. But markets don’t move based on what should happen in the short-term. They move based on where the money is flowing right now.
This is why some breakouts explode higher. This is why crashes happen faster than rallies. This is why momentum can continue far longer than expected.
Once liquidity starts moving aggressively in one direction, price can move much further and much faster than logic suggests.
This is also why smart traders pay close attention to:
• Volume
• Momentum
• Breakouts
• Market structure
• Institutional activity
These are all clues about liquidity.
Because in trading, being early can feel exactly the same as being wrong.
