A photocell is any of a wide range of sensors that react based on the presence of light or electromagnetic energy. They can be found in many different forms, from solar panels that use light to generate electricity, to photoresistors, which shift in resistance based on how much light is present.
Bond prices and yields are like a seesaw: when bond yields go up, prices go down, and when bond yields go down, prices go up. In other words, a move in the 10-year Treasury yield from 2.2% to 2.6% indicates negative market conditions, while a move from 2.6% to 2.2% indicates positive market performance.
Online brokerages may offer bonds with a flat commission or they may offer them on a ânet yieldâ basis. Most other dealers including specialty bond dealers will almost always offer bonds on a ânet yieldâ basis. âNet yieldâ simply means that the yield you see for any bonds already includes the dealerâs profit or mark up. For instance, if you see 3.25% yield-to-maturity offered online, the dealerâs profit is already included. There is no commission; you will receive the stated yield-to-maturity of 3.25%. Other times, an online brokerage might offer a flat commission of $10 or $25 or $50 to execute a trade. This usually means that the brokerage does not own the bonds, but is going to execute a trade on your behalf and buy the bonds from a dealer that owns the bonds.
