Have We Found a Winning Bet?
I conducted a similar analysis. Because the IW awards are typically given in October, I looked at the stock prices from Oct 1 to Oct 1 each year. With the stock data that I had handy, it was only easy to go back to 10/1/2001. So, the “2001” year shows stock returns from 10/1/2001 to 9/30/2002. The last winners I analyzed were the 2004 winners, looking at their stocks up until 9/30/2005.
Industry Week award winners did much better than the Shingo winners over the past four years. The total return was positive. Yes, we can call it a return rather than a loss. The four-year gain for the IW portfolio was 30%, compared to a four-year loss in the Shingo portfolio of 69%.
2003 IW winners: Autoliv (up 28%), Boston Scientific (down 38%), Dana, Delphi, General Cable (up 32%), Textron (2 plants, up 58%), and Lockheed (up 18%).
2002 IW winners with notable stock gains: Siemens (up 75%)
2001 IW winners with notable stock changes: Dell (up 34%), Kodak (down 24%), Northrop (down 43%), MKS Semiconductor (down 37%).
So am I willing to bet my retirement fund on the 2005 or this year's upcoming 2006 winners? Hmmm…. not sure.
IW Best Plants isn't a “lean prize” per se, but there are many lean companies in the IW list and there's some overlap with Shingo winners. Here's the criteria for winning, you can see it's much more broadly defined. Being a lean company (or even just a lean factory) whould lead to improvements in all of the areas IW looks for, except maybe for “application of new technologies.”
A panel of IW editors reviewed the applications, which reported management practices and plant performance in such areas as quality, customer and supplier relations, employee involvement, application of new technologies, productivity, cost reductions, manufacturing flexibility and responsiveness, inventory management, environmental and safety performance, new-product development, and overall market results.
Why is it that IW Best Plants stocks are “winners” while Shingo stocks are “losers,” in general. What do you think? Click “comments.”
