Many bond investors suffered declines as a result of both risks.
The Federal Reserve has been buying both Treasurys and agency mortgage-backed securities at a rate of $85 billion per month.
The Fed has undertaken this program of quantitative easing in order to keep interest rates at very low levels, thereby stimulating investment and consumption.

This fortifies the economic headwinds they are facing already.
In stock land, earnings season is in mid-stream.

Reports continue to show lackluster revenue growth with modestly better gains on the bottom line. It strikes us as illogical that earnings will remain robust without increasing revenues.
Price-to-earnings multiples remain a bit above average and earnings margins for the S&P 500 are near all-time highs. If the gains in the equity markets are to be maintained, revenue growth must resume.
We have been through these ambiguous periods before and know that they can last much longer than most ever expect. When prices seem to creep ahead of fundamentals, we conclude one of three things: our evaluation is flawed (and prices and fundamentals are not out of line); fundamentals will improve to support prices or; prices will come down to a level supported by the fundamentals.
It is really important at periods like this to make sure that your holdings have substance: strong balance sheets, highly visible revenue and income streams, market share, and high-integrity management.
