Clear filtersFloat and Shares Outstanding
Float is the number of shares actually available to trade: shares outstanding minus insider and restricted holdings. A small float explains a great deal of unusually fast price movement.
Bonds: Coupon, Par, Price and Yield
A bond is a loan cut into tradable pieces. Its price and its yield move in opposite directions by arithmetic necessity, and that single fact drives most of what happens in fixed income.
The Treasury Yield Curve
The curve plots what the US government pays to borrow across every maturity. Its level, its slope and its changes are the most watched picture in macro.

Currencies are quoted in pairs, so every quote is a ratio between two things that both move. For equity traders the dollar is the pair that matters most.

Going Public: IPO, Direct Listing and SPAC
Three routes to a public listing, with different mechanics, different disclosure and different consequences for the shares that arrive on the market.
