My portfolio is not doing that well at least comparatively to what the stock market is doing. I am only 30 so I don't have hundreds of thousands of dollars to play around with but my savings are about 30K. I have about 20K out of that 30K is either global stock funds or commodity funds and the remaining 10K in the U.S. stock market. Its frustrating to watch the stock market shoot ahead while my portfolio flat lines. At the same time, I feel fundamentally the only thing keeping this stock market at its current levels is the cheap money from the federal and depressing interest rates. The market is not that great and I don't trust myself to time my exit at the right time so I am intellectually okay with my situation even though its frustrating.
I wouldn't say that Federal Reserve policies (I assume that's what you're referring to by 'the federal') are the only things keeping equity markets this high, but the markets are quite sensitive to those policies and speculation about them going forward. The Fed has definitely pushed capital toward certain kinds of assets, to include equities.
But earnings have also been strong, equity companies in general are doing well. That's a big part of why equities are at their current levels (though earnings themselves can be affected by Fed policies). That can of course change as we move forward, but current equity prices reflect current (equity) business realities reasonably well.
