Warren Buffett’s Best Investing Tips

Warren Buffett is one of the best investors in history, and is widely regarded as the "Oracle of Omaha."

Buffett is a value investor at heart, but he also shares a lot of other insights during shareholder meetings and in his annual letter to shareholders. As such, it is pretty easy to understand Warren Buffett's investing philosophy.

Plus, since his holdings are so widely followed, you can check his portfolio anytime at the CNBC Berkshire Hathaway Portfolio Tracker.

While over time he has thrown out a ton of different tidbits on investing, here are the top five investing tips Warren Buffett has given:

1. Cash Is King

Cash is a big deal to Warren Buffett, and he keeps a lot of it on hand at any given time. The reason? In Warren Buffett's words, he keeps a lot of cash on hand "so that we can both withstand unprecedented losses and . . . quickly seize acquisition or investment opportunities."

Also, in his 2011 letter to shareholders, Buffett reprinted a note from his grandfather from 1939: "I have known a great many people who at some time or another have suffered in various ways simply because they did not have ready cash . . . I hope it never happens to you."

That is solid advice for personal finance. You always want to maintain an emergency fund for the unexpected, but you should also keep cash in your brokerage account ready to go so that you can buy things on the dip.

For example, if you had piles of cash waiting to invest when the financial crisis hit, you could have bought low and sold high, reaping huge 50% to 100% profits on your investment. However, if you had everything tied up in investments, you would have just suffered large losses.

2. Be Fearful When Others Are Greedy

One of Buffett's most famous phrases is, "Be fearful when others are greedy, and greedy when others are fearful." This great sentiment is very true of our stock market and investing system.

The bottom line is that you should avoid the stocks that everyone else is buying, as they probably are overvalued. Instead, look for the stocks that few people are paying attention to, check their fundamentals, and invest if it makes sense.

3. Dividends Are Your Friend

Buffett loves dividends, as do most value investors.

Dividends are a great perk to buying a company, as it usually shows that the company's finances are in good enough shape to support paying out its hard-earned money.

Buffett likes companies that have a long history of paying dividends, and even increasing them over time. A popular tracker of these type of stocks is the Dividend Aristocrats, which are companies that have increased their dividends over the last 25 years.

Plus, Buffett recently announced that there is a good chance that the total amount of dividends paid by his position in Coca-Cola will soon surpass what he paid for the stock. That is a great return on investment!

4. Always Buy Undervalued Stocks

Buffett is a big-time value investor, and always looks to buy undervalued stocks based on their intrinsic value.

He calculates the intrinsic value by looking at the company's fundamentals — at a minimum of over the last five years, sometimes longer. He looks a lot at return on equity, operating margins, and having little or no debt. He compares the company to its peer group, and likes to see if it is undervalued.

A key part of this is also looking for companies that have some type of monopoly or special trait that will enable it to be successful in the future. This could be technology (even though Buffett avoids tech stocks that he doesn't understand), or even management. All of these factors can contribute to intrinsic value.

5. Buy and Hold

Finally, Buffett is a true buy-and-hold investor. He holds his positions for a long period of time, and constantly reiterates this to his followers.

In fact, he has said that he likes to "buy and hold forever." And it is true, since he has owned many of his positions for over 20 years, which is eons in the investing world.

However, he has also said that this doesn't mean hold a company if the fundamentals have changed. Buffett constantly looks at his portfolio and if a company loses its edge or superiority, then he does sell or trim back his position.

He also is a huge believer in patience. Basically, don't trade, invest. Find companies you like, and wait for the right price. It has been said that Buffett has a list of hundreds of companies that he wants to invest in, but that he is waiting for the right price and opportunity.

The last time he went on a buying spree was the Great Recession, when stock prices tanked. He was able to scoop up deals and get in on prices that made him get great returns in the following years.
