NEW YORK ( TheStreet) -- Tonight, after the market close, Tibco Software ( TIBX) is set to report earnings. With a PE ratio approaching 57, this is not a cheap stock even with a year-over-year quarterly revenue growth rate of 23% and EPS quarterly growth rate of 21%. I am not a fan of buying in front of earnings reports and feel the same about Tibco. I would much rather be a buyer of weakness, not trying to chase strength. If Tibco witnesses selling pressure as a result of earnings, then I might be interested in adding to my existing position though and here's why. If you compare Tibco to its larger competitors, the price performance of the stock is astounding. Here's a chart with the five largest competitors. The only company that comes close is Oracle ( ORCL - Get Report). When you think about Oracle, a stock that is in the headlines practically every single day yet, and then you realize that Tibco has easily outperformed even them, you wonder why you don't hear more about Tibco.
