If you're interested in what a Fourier Analysis looks like, there's a software programmer Greg Thatcher who has done a very nice analysis of many stocks and funds.

I took your example, PSEC, and ran it in his site here
Fourier Analysis of PSEC

It indicates the cyclical waves of the stock in time periods.

The site also does a seasonal analysis of stocks which indicates when buying or selling opportunities may present themselves.
Seasonal Analysis of PSEC

Is it right or wrong??? Depends on the programmer, your belief in the metric, and your risk tolerance. I'm not advising at all nor do I have anything to do with the site, I just find the analysis interesting and fun to do.
