National Presto Industries (NPK) operates three separate businesses, each somewhat straightforward to analyze: a housewares business, an absorbents (private label diaper) business, and a Department of Defense munitions supplier. We originally looked at NPK when it was trading near the $130 range, but decided the stock was a little too expensive for us after a cursory analysis. We set a price alert at $105 and put it on the back-burner. When the price fell below our target last week, we resumed the research process. Over the coming month, we’ll try to determine a fair valuation for each segment independently. This analysis is being done real-time, meaning we’re not sure what conclusions we will draw from it. We haven’t yet made an investment and we’re not sure if we will. But the valuation appears reasonable, definitely worth taking a look at, and we hope that progressing through the research process with us will be an entertaining experience for our readers…
