Since it is an objective measure, there is not a scintilla of room for negotiation -- a dollar is a dollar, right? To you, then, this risk trumps all others. What is the risk I'm referring to? I call it quote risk. Quote risk is the risk that the price quote for your stock might go down. Quote risk is a worry for investors that attribute too much meaning to quotes. The typical investor puts $10,000 into a stock; when the quote drops by 30%, he announces with certitude, "I've lost $3,000." To a value-centric investor, a price quote is a bid, an offer. That's all it is. A price quote tells you the dollar amount you can secure if you sell your property today. If you buy stock at a discount to value, it doesn't make sense to sell your property just because the offer price declines. If you own the local car wash and someone offers you 75 cents per dollar of value, does it mean you've lost 25%? Do you call your spouse and say, "Honey, we've lost 25% of our business value today." Of course not. You received an offer. That's all. The bid doesn't come attached with a detailed appraisal of value. If you own the car wash and you're rational, you know that full and fair offers occur infrequently. If you're interested in selling the car wash, you know that you'll likely have to wait several weeks, or even several months, before you get an offer that approximates value. To a long-term value investor, quote risk is irrelevant. I paid 40 cents per dollar of value, or $17 a share for Tecumseh Products ( TECUA) Class A shares last year. A few weeks later, the quote dropped by one-half. I didn't look at the quote and exclaim, "I've lost 50% of my money!" I didn't lose anything, because I wasn't about to play giveaway. I wasn't about to accept an offer that was a tiny fraction of value. While price eventually migrates to value, anything can happen in the short term. Chalk it up to quote risk.
