What are prices?

A layperson’s guide to understanding charts and volatility.
1/

It’s an observable fact that price has nothing to do with value. Perhaps over the long term these two converge, but in the short term it makes no sense that the price of, say, soybeans would change 3-4% from day to day.

So what’s happening?

You’ve probably heard people say “markets are forward looking” and that’s sorta true, I guess.

But that doesn’t mean they’re any good at it.

It might be better to say “markets consistently attempt to look forward” because that would be more illustrative of what’s happening.

When a day-over-day price makes a 3% move this is not a 3% shift in value, it’s a 3% shift in *aggregate expectations about future value.*

And that makes sense, right? Expectations are pretty ephemeral so they can move fast.

Consider volatility through this same lens. When a market is highly volatile, this means that expectations about forward value are evolving rapidly.

This happened in March when everyone got scared about Covid - it broke people’s forward expectations, and thus broke markets.
