At 6:30 in the morning a salesperson on a trading floor has about ninety seconds to tell a client what happened overnight and what it means for that client's positions. Nobody wants a list of prices. They want the story that connects them: yields fell after a soft inflation print, so stocks rallied, the dollar slipped and gold rose. That story is the product a desk sells as much as any trade.
Interviews test the same skill. "What is going on in markets?", "a shock hits overnight, what moves?" and "why did that stock fall on a beat?" are all one question: do you know why prices move, and can you connect one market to another? This lesson gives you the connections. It never gives you today's levels, which go stale in a week. Get those from the Markets Hub the morning of the interview and say "as of this morning."
Every move has a reason, and two questions find it. First, what kind of news is it, growth or inflation? That decides whether stocks and bonds move together or apart. Second, what was expected? Prices already hold the forecast, so assets move on the surprise and on what it changes about the future, not on whether the news sounds good.
The map
| Asset | What mostly drives it | In a risk-off move |
|---|---|---|
| Stocks | Expected earnings, and the rate used to discount them | Down; cyclicals most, utilities and staples least |
| Treasuries | Expected Fed path, inflation, term premium | Up in price, yields down (unless the shock is inflationary) |
| Dollar | Interest rate gaps with other countries, risk mood | Up, with the yen and Swiss franc |
| Gold | Real yields, central bank buying, fear | Usually up |
| Oil | Supply decisions and disruptions, global growth | Down on a growth scare, up if supply is hit |
| Credit | Default risk, risk appetite | Spreads wider, high yield most |
| Volatility | Uncertainty, demand for protection | Up |

Frequently asked
- Do stocks and bonds move in opposite directions?
- Only when growth is the market's main worry. Bad growth news hurts earnings and makes rate cuts more likely, so stocks fall and bonds rally. When inflation is the main worry, higher expected rates hurt both at once, which is why stocks and bonds fell together in 2022.
- What happens to markets in a geopolitical shock?
- The usual risk-off move: stock futures fall, Treasuries rally, the dollar, yen and Swiss franc rise, gold usually rises, the VIX jumps and credit spreads widen. The big exception is a shock to oil supply, which is inflationary and can push bond yields up instead of down.
- Why would a stock fall after beating earnings?
- Because the price already reflected expectations, often higher than the published consensus, and because the market cares more about the future than the quarter just reported. A cut to next year's guidance usually outweighs a beat, since most of a stock's value sits in later years.
- What is a safe withdrawal rate from a portfolio?
- The common rule of thumb is about 3.5 to 4 percent of the starting value in the first year, then the same dollar amount raised with inflation. It comes from asking what draw would have lasted about thirty years through bad historical starting points. It is a guide, not a law.
