Fed Days Become Non-Event Days

Weekend Reading from Bespoke »

While it barely made news, the Federal Open Market Committee (FOMC) last week held the first of its eight regularly scheduled meetings for the year.  On Wednesday -- the day that the Fed released its policy statement from the meeting -- the S&P 500 gained 0.42%. 
For those that have been following the markets for longer than a year or so, a change of 0.42% on a Fed Day seems pretty small.  Up until just recently, the market would move around like a jumping bean on Fed Days as investors reacted to policy changes and tried to interpret what Ben Bernanke and his predecessor Alan Greenspan had just done.  But it has now been 538 days since the Fed last changed the Fed Funds Rate, and the inactivity has become so telegraphed that traders are hardly aware of when the next Fed Day is, nor do they care.
