It's controversial.
It shows readers a new point of view.
When it's a buyer's market, it means the supply is greater than the demand. When this happens, buyer is king. He or she can afford to pick and choose from the vast pool of supply available.
When it's a seller's market, it means the opposite. The demand is greater than the supply. The seller can afford to jack up the price without fear of no buyer.
All businesses and industries face some kind of fluctuation in demand from time to time. It could be due to seasonal issue, poor economic conditions, regulations, etc. Business owners are also subject to changes in supply such as more competitors entering the market, increased output by themselves or competitors, poor harvest, and so on.
Some businesses seek to control price by controlling the supply. They may hold back stocks, lower production, if they can be manipulated, to make supply scarce.
As for demand, can you control it?
Now, what about nobody's market?
Does it mean a market that do not belong to either the buyer and seller, where the supply is in equilibrium? Of course, this exists in a perfect economy. In reality, it seldom happens.
The article talked about the property market after the government introduced cooling measures to curb rising housing prices. So I would assume it is talking about no buyers where nobody is buying.
Think about it, no matter how bad the economic condition, how harsh the rules, how weak the demand, there are still people buying and sellers selling. Likewise, in good times, there are people not buying and sellers not selling.
When things go wrong, we tend to look at conditions outside of us. We blame it on the weather, the rules, the competitors, the location, the economy and whatever excuses we can find.
However, the problem has got nothing to do with outside conditions. You've to look inside of your business first. Challenge all the assumptions you've made about your industry, your customers, your suppliers, etc.
Rather than saying it's a buyer's market, a seller's market or nobody's market, could it be a nobody's market in a buyer's market or a nobody's market in a seller's market?
