Discount rate raised from 0.25% to 0.75%. No change to Fed Funds rate. Might spice up the markets tomorrow.
Is discount that important? And ..... Why before expiration day? Some people might get burned by the timing of this.
One of the more profound observations I came across reading a Quant book on alpha strategies, was that increasing rates is a sign the economy is improving. He showed that contrary to common thinking, as the rates start going up, the market tends to move in the same direction. Think of how the 1st of a succession of rate 'cuts' often signals an impending crash. If you go back and look through the historical record, you'll see these facts. Be careful to extrapolate common perceptions.
'Finding Alpha', E Falkenstein. Although he discussed the rate increase phenom, I pretty much discovered the cut phenom on my own.
