Looking for stock market diamonds in the rough?
Four-star fund manager Jerome Heppelmann finds them in a couple of tech stocks that have really been roughed up.
His Old Mutual Focused Fund is up an average of 14.4 percent per year over the last five years.
He likes analong semiconductor company Maxim Integrated Products, despite some serious problems.
"They haven't filed their financials since `06; it's been de-listed, taken out of benchmarks," he told CNBC. "Those might seem like negatives, but it explains why the stock is down so much."
He sees Maxim rebounding strongly by mid-year, after its financial statements have been straightened out and filed.
Heppelmann also likes EMC, although it has been battered by the economic downturn.
"What we want to look for is companies that have priced-in most of the weakness," he explained. "I just look at storage as one of the killer app[lication]s of Web 2.0, so to speak."
