Supply and Demand 101
Why prices move
One simple idea explains almost everything.
Demand: want drives price up
More buyers chasing the same thing — prices rise.
Supply: more of it, lower price
Flood the market with options — prices fall.
Equilibrium: the market agrees
1 price where buyers and sellers both say yes Supply meets demand
Now you see it everywhere
Gas prices, concert tickets, housing — same two forces, every time.
