The opportunity I'm about to describe is one that is 100% in Goldman Sachs' (NYSE: GS) wheelhouse. Yet the Wall Street bully botched it.

Meanwhile, the five companies I've found have a chance to beat Goldman, beat the market, and make a ton of money for their shareholders.

Let me explain
Goldman Sachs' Ivy-League-trained employees make their living mastering the markets. They help companies do IPOs, raise debt, and buy other companies. They make markets and execute trades for clients. And (though regulation has now hampered this somewhat) they trade in the markets themselves.

And they're damn good at the trading.

How good?

In the first quarter of this year, Goldman's trading desk was profitable 63 days out of 63. Imagine doing that in your own brokerage account!

These weren't just small gains, either. On 35 of those days, Goldman made more than $100 million. Each day.

But they didn't make money on this trade

Even a novice investor sees where Goldman should have bought into its own stock -- the crater in the fourth quarter of 2008 and the first quarter of 2009.

What actually happened was that Goldman Sachs loaded up on its own stock at the worst time. At the height of the good-times housing bubble, it bought back a net $5 billion in 2006. In 2007, it accelerated its repurchases to $8 billion. Then, when the bubble burst and its stock price hit lows, it sold almost $20 billion of common and preferred stock in the fourth quarter of 2008 -- and subsequently sat on its hands in the first quarter of 2009.

Now, to be fair, Goldman hit the worst financial crisis in most of our lifetimes (knock on wood). And it needed to raise that capital-- both via the government and privately -- or face the fate of Bear Stearns and Lehman Brothers.

That said, Goldman makes much of its money from the art of the trade -- and it bought high and sold low. On its own stock!

I don't tell you this to bash Goldman
No, I'm using this example to show how hard it is for any company to time its share buybacks. This high degree of difficulty is one of the reasons many investors prefer dividends to stock repurchases.

It's why many see American Capital Agency's (Nasdaq: AGNC) 20% dividend yield and buy in. As a REIT, American Capital Agency has to pay out 90% of its profits, so its management isn't tempted to repurchase mass quantities of stock at inopportune times.

Don't get too excited, though. The irony of the REITs is that because they have to pay out their profits, they have little money saved up for tough times. They end up in danger of doing exactly what Goldman had to do -- issue shares at the worst possible times.

Now I'm usually a big, big fan of large, sustainable dividends, but if a company could make repurchases at periods when its stock price is low, it would be even better than dividends. It creates shareholder value without creating a tax event.

And this is just the opportunity those five companies I mentioned earlier have got on their hands.

The opportunity
To take advantage of share buybacks, a company needs plentiful cash. It also needs a cheap share price.

I went on the lookout for candidate companies by trolling the five-year-low list for companies that have a ton of net cash (i.e. cash less any debt). Here are the five companies I came up with.

Now, I'm not saying each of these companies should definitely pounce on share buybacks. They have to answer "Yes" to two questions first:

  • Is its stock actually undervalued (not just near a 5-year low)?
  • Can the company spare some of the cash (or does it need it for financial flexibility)?

As investors, we hope these companies make the correct call. But we can also take action on our own. Remember, these are companies trading near five-year lows with their share prices buoyed by cash in the bank.

I took the plunge on FormFactor a few months ago despite the company bleeding cash. I'm betting on a turnaround after a recent management shakeup. It's certainly possible the company continues to flounder -- the semiconductor testing equipment space is a tough one. But fortunately, management has a lot of room for error. The stock trades for $8.92 a share. That price is supported by $7.91 a share in cash!
