Timberland (NYSE: TBL) was the inaugural stock purchase for my Rising Star portfolio. As of this writing, it's also become the portfolio's first double since my November purchase. Although many investors would view this as a good opportunity to take the money and run, I'm holding.

True, Timberland's trading at 24 times earnings, far higher than the trailing multiples attached to rival shoe companies like Steve Madden (Nasdaq: SHOO) at 18, Skechers' (NYSE: SKX)  mere 7, and even mighty Nike (NYSE: NKE) at its own 18. And sure, I'd usually poke fun at paying this kind of multiple for a shoe company. I certainly wouldn't want to pay the same 24 times earnings at which Crocs (Nasdaq: CROX) currently trades.

Here's my hold rationale: I'd still believe that Timberland's future remains bright, whether its stock price went up, down, or sideways since November. It possesses a well-known brand name, and more importantly, big ideas. At 1.24, its PEG ratio makes the stock seem reasonably valued compared to growth predictions. I also suspect that analysts haven't fully figured Timberland's competitive strengths into their estimates, so that ratio may not adequately reflect the growth Timberland's got coming. In other words, the company could be even cheaper than it looks now.

I designed this portfolio to be inspired by socially responsible, or impact, investing; it's also meant to reflect being a stock buyer, not a renter. I'd rather not sell unless a stock seems insanely overvalued -- in which case the money might be better utilized elsewhere -- or if something seems to have gone very wrong with a company's business prospects. I plan to do my best to practice the art of patient stockholding, even if the ride occasionally gets a bit bumpy.

When I bought shares of Timberland for this portfolio, I never tried to argue that its price would double in such a short time. I bought Timberland because its management pursued a green, environmentally conscious ethos far before that thinking was "hip." Timberland has held that authenticity in its corporate DNA for years; its pioneering attitude carries greater weight than any desire for a quick double.
