Try as she might, sometimes Mary Lisanti can't keep her mind off work. Take the time a few years ago when she was a securities analyst and her car broke down during a weekend getaway. While her husband dealt with the mechanic at an auto shop, Ms. Lisanti's eyes fixed on a truck parked outside, emblazoned with the word SafetyKleen. Her curiosity piqued, she investigated. What she found was a small manufacturer that was cleaning up with a product for de-greasing tools and car parts.
It was a great little company they were the Gunk guys, Ms. Lisanti recounted over lunch in her office. She ended up recommending a buy on the company's stock. Such attention to the details of everyday life has served Ms. Lisanti well in her job as manager of the BT Investment Small-Cap Fund.
