(The following commentary comes from an independent investor or market observer as part of TheStreet's expert contributor program.)ARMONK, NEW YORK ( TheStreet) -- Technology bellwether IBM ( IBM) isn't getting the respect it deserves, so any pullback under $200 would represent a tremendous buying opportunity. IBM is worth a closer look for a variety of reasons, not the least of which is the fact that the company has been on a considerable tear all year and has logged what seems like a new 52-week high each week. The company's recent performance interests me quite a bit because it is hard to imagine that just a few years ago the company known as "Big Blue" was teetering on the verge of irrelevance. IBM languished under a stifling corporate culture and a crackpot attempt to take over the consumer and business technology hardware and software market. Today, IBM is once again a beacon of power and one that along with Apple ( AAPL) has led technology resurgence that two quarters ago seemed unimaginable. Going into IBM's earnings announcement on Tuesday, I was eager to see if it would be able to build on the momentum that started at the beginning of the year.
