Sometimes the stocks that you don't buy shape your portfolio returns as
much as the ones you do buy. That feels true for me right now, as
holding off on buying F5 Networks (Nasdaq:FFIV)
seems to have spared me a pretty negative reaction to these fiscal
fourth quarter results. Although I still believe in the growth story at
F5, it's hard to deny that there are more risks and challenges now than
over the past year or two.
