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.
Since last summer, the yield on 10-year Treasury securities jumped by more than a full percentage point, from 1.37% in July to more than 2.4% today. For fixed income investors, rising interest rates pose a big challenge, since older, lower-yielding bonds held in a fund are likely to fall in price when market rates rise. That explains why, over the past three months, the average long-term government bond fund has lost nearly 8% of its value, according to Morningstar. But âthere is a benefit to rising rates,â says Matt Toms, chief investment officer for fixed income at Voya Investment Management.
