News flash! Whenever you sell a stock, the person buying it likely thinks you're making a mistake.

And there has been a lot of selling recently. In fact, over the past two months, the average daily volume for the S&P 500 has been 6.45 billion shares. That's 2.5-times higher than the average of the previous five years. It's also 1.5-times higher than the last year alone, as the markets fell from their highs of a year ago. This is, officially, a frenzy.

And the reason there's been so much selling is because there's a whole bunch of "it's-end-of-the-world-as-we-know-it!" news. People are pulling their money out left and right, and either selling their holdings outright, or forcing fund managers to sell in order to pay out redemptions.

You're selling what?
For instance, we hear that holiday sales are going to suck, so people sell off retailers like Dell (NASDAQ:DELL) or Best Buy (NYSE:BBY) because of the perception that they are going to take one on the chin. Both of these stalwarts are down more than 30% in the past two months alone.

The panic has punished companies in every industry -- from retailers and restaurants to oil and agriculture. Yum! Brands, ExxonMobil (NYSE:XOM), and Monsanto (NYSE:MON) are all trading at multiyear low multiples.

But guess what? Somebody's buying those shares you're selling.

Maybe it was Robert Olstein, manager of Olstein All Cap Value (OFALX) and co-founder of "The Quality of Earnings Report." He delves into the financial statements of the companies to find those that generate lots of free cash flow, avoid aggressive accounting, and are selling at a discount to his estimate of value. This has allowed his fund to post annualized returns of 7.6% since inception in late 1995, versus 3% for the S&P 500.

He increased his position in Dell last quarter, along with other consumer-facing companies like Macy's (NYSE:M) and Office Depot. He's also been stocking up on some of the more indirectly hit financials like NYSE Euronext (NYSE:NYX).

Or, it might have been David Dreman. He runs the Dreman High Return Equity fund (KDHAX), which has returned 9.5%, after charges, on average per year since its inception in the spring of 1988. The S&P? It only did 5.6%. His fund has large positions in beaten-down companies such as ConocoPhillips (NYSE:COP). He looks for below-market price metrics like P/E, strong balance sheets, and dividends. Right now ConocoPhillips qualifies with a 3.7 P/E, debt-to-equity of 24%, and a dividend of 3.8%.

Getting it right side around, not backwards
Long-time successful value investors are snapping up shares left and right, knowing that the market has mispriced the long-term performance of many companies. Yes, companies will face troubling times over the next several months, but many of them are going to survive that and go on to new highs. And these guys have seen it all before.
