Answer should contain five different factors. Bond Market Interest Rates: Rising interest rates generally cause bond prices, including those of FLBDNX.US, to fall, as newer bonds offer higher yields. Lowering rates have the opposite effect.

Credit Risk Perceptions: Changes in investor sentiment regarding the creditworthiness of the underlying bonds in the fund influence demand. Increased perceived risk lowers prices, while decreased risk increases them.

Inflation Expectations: Higher inflation erodes the real value of fixed income, leading to lower bond prices to compensate for the anticipated loss of purchasing power. Lower inflation expectations can increase prices.

Economic Growth: Strong economic growth often leads to higher interest rates and potentially increased inflation, both of which can negatively impact bond prices. Weaker growth might spur lower rates, benefiting bonds.

Fund Flows: Large inflows into FLBDNX.US can drive up demand and potentially increase its price, while significant outflows can put downward pressure on the price as the fund manager sells bonds to meet redemptions.
