When you’re dealing with a billionaire like Bill Gates or Warren Buffett, it’s almost impossible to keep track of the price of your stocks.

And the fact that Barclays is the first to make this kind of deal at a time when more than a dozen major U.S. companies are trying to get in on the action shows that there is something to be said for diversifying your portfolio.

But the fact is that you can’t just keep track, and if you don’t, your shares will likely trade at the low end of the market, and that could be bad news for investors.

“We’re seeing that it’s becoming harder and harder for the large and small to be in the same market, or even in the market together,” says Bill Bower, chief investment officer at Capital Advisors.

And while there are plenty of ways to hedge against this risk, there are a few that are far more effective than others.

For starters, you need to have enough cash to cover your bets.

“You don’t want to be investing on a balance sheet that is not fully capitalized, but you also don’t need to be shorting stocks or bonds,” says Andrew B. Pincus, founder of Pincuses Capital Management, a hedge fund focused on long-term investments.

You also don.

In fact, it might be best to hedge the risk by selling your own stocks rather than buying them, says Stephen L. Green, an adviser to Berkshire Hathaway.

And that’s why, for instance, the funds that hedge stocks and bonds are often called “bonds hedgers.”

Investors in those funds typically have an interest in keeping the market price of the securities they hold close to the current price of those same securities, which is why they often hedge against the risk of inflation.

“There are a lot of strategies for hedging, but the best strategy is a diversified portfolio,” says Green.

“It can be very good if you have a little cash, but it’s not always the best way to do it.”

Another way to mitigate risk is to have a portfolio that’s balanced, says John Bowerman, president of The Vanguard Group, a wealth management firm that has been investing in the stock market for more than 50 years.

“The biggest thing to look at when you’re shorting is whether you have enough liquidity in your portfolio to cover the loss in value of your investment,” says Bowermans investment manager.

If so, the Vanguard portfolio can include a number of options, including buying a short-term or long-duration security like a stock or bond that’s undervalued, or holding a basket of stocks and bond funds that are valued at more than their fair value.

And of course, there’s the option of using a short position in a company, like buying a small position in Apple or Google or Twitter.

But most importantly, if you’re a long-shorting investor, there is a way to make sure your investment doesn’t take a dip.

That’s why Vanguard is one of the most trusted companies in the U.K. to track the performance of individual stocks.

The firm, which also manages the U, has a track record of hedging over the past decade, Bowermen says.

And its hedging strategies are particularly important when it comes to stocks like Apple, where it’s easy to get carried away.

“When you get a bear market, we can take a position in some stocks that have underperformed over the last few years and make sure we’ve hedged that position,” Bower says.

It’s the same strategy used by Vanguard’s own portfolio manager, which does the same thing, as it does for its own stocks, Bowers says.

For those reasons, the company recommends that investors only hedge short positions in stocks with less than their risk of losing their value, he says.

“For most people, there will be enough cash in their portfolio to do that,” he says, “and that is the biggest asset in the portfolio.”

So, the best advice for long-to-short investors is to buy what they’re willing to lose, and to be careful about when they sell.

“This is a great time for short sellers to take a stand and buy low,” says John E. O’Neill, a senior portfolio manager at Vanguard.

But for the longer-term investors who are long the stock, it can be a tough call.

For example, if an index fund is undervalued but you’re able to get the price to go up, you might be able to buy it for less than its fair value, or you could be able buy it at a loss, according to Green.

So, if it looks like a bear rally is coming, diversify your holdings to minimize the chance that you’ll end up shorting.

But in general, if a stock is trading above its fair market value, diversifying to lower-cost holdings is an option that is still worth
