NEW YORK (TheStreet) -- Be prepared for another wild week of earnings, Jim Cramer told his Mad Money viewers Friday as he laid out his game plan for next week's confounding stream of news and quarterly updates.

On Monday, Cramer will be watching Action Alerts PLUS holding Kraft Heinz (KHC - Get Report), ith its powerhouse of brands. He continues to recommend both Kraft Heinz and Mondelez (MDLZ - Get Report) now that activist Bill Ackman has taken an interest. Also on Monday, Live Nation (LYV - Get Report) and Shake Shack (SHAK - Get Report) report. Cramer remains a fan of concert promoter Live Nation, but panned Shake Shack as still too expensive to own.

Tuesday brings an analyst meeting from O'Reilly Automotive (ORLY - Get Report), which is sure to buoy not only that stock but Advance Auto Parts (AAP - Get Report) and Cramer fave AutoZone (AZO). Cramer said he'll also be listening to pet food maker FreshPet (FRPT - Get Report) to see if this company is any closer to profitability.

Next, on Wednesday, it's Macy's (M - Get Report) reporting along with Alibaba (BABA - Get Report) and network equipment maker Cisco Systems (CSCO - Get Report), another Action Alerts PLUS holding. Cramer recommended buying Macy's both before and after it reports, but said to wait until after Cisco reports before making any decisions there. As for Alibaba, Cramer is decidedly not a fan but still likes Yahoo! (YHOO), which holds a stake in Alibaba.

Of the retailers reporting on Thursday, including Nordstrom (JWN - Get Report), Kohl's (KSS - Get Report) and J.C. Penney (JCP - Get Report), Cramer only endorsed Nordstrom, the well-run retailer that remains a perennial favorite.

Finally, on Friday, it's the big news for the week: the latest producer price index. Cramer said investors should be prepared to learn that prices for all sorts of things are in decline, which means there's no inflation and thus no reason for the Federal Reserve to rush to raise interest rates in September or October.

Cramer's Investment Rules

After almost a decade of telling viewers "there's always a bull market somewhere," Cramer said it's time to revisit the most important investing rules he's learned over these many years. Many of these rules he's learned the hard way, but fortunately you can benefit from his many mistakes.

Rule number one is something you've likely heard Cramer say on every show: Bulls make money, bears make money but hogs get slaughtered. What does that mean? It means taking a profit is a good thing.

Cramer said it doesn't matter if you make money when the market goes up or by shorting it and making money on the way down. The only true way to get hurt is to think you know it all and never take any of your winnings off the table.

For every stock in your portfolio there should be a price you're willing to pay and a price you're willing to sell. That's just common sense, Cramer added. The markets take stocks up and down for all sorts of irrational reasons. When you have solid gains, take them.

You don't have to sell everything, Cramer added. But when things get crazy expensive and you have a lot of gains, don't let those gains turn into losses.

Pay the Tax Man

Cramer's second rule for investors: It's okay to pay taxes. Cramer explained there have only ever been two times when he's encouraged investors to take large chunks of money out of the markets. Those times were right before the dot-com bust of 2000 and the Great Recession of 2008.

Yet, after both of those warnings, Cramer said, he heard the same objection from investors. They didn't want to pay short-term capital gains taxes and wanted to let their newfound winnings ride until they hit the long-term threshold. The only problem? Stocks tanks a lot further and a lot faster than any marginal taxes changes.

Never let the fear of having to pay taxes be a reason to hold a stock, Cramer said. If a stock goes up too far too fast, trim a little and take some profits.

Not wanting to pay the tax man is perhaps the single biggest investment mistake people have made in our generation, according to Cramer. Taxes never trump the fundamentals. Stocks can be dangerous whether they are owned for the short term or long term.

Avoid Broken Companies

Another important rule investors must master: Look for broken stocks, not broken companies.

Cramer said most people closely affiliate the stock of a company with the company itself but that isn't always the case. In a market dominated by exchange traded funds, or ETFs, that lump stocks into big baskets, stocks can be completely divorced from their underlying fundamentals, making for some lucrative opportunities.

The markets are full of bad companies with bad stocks, Cramer said, but there are also lots of good companies with bad stocks. The key is to identify those with solid fundamentals, preferably those that have recently reported and told you their fundamentals are strong yet have seen their stocks sell off with the broader markets.

Don't buy damaged goods, Cramer told viewers. No company's stock falls below $10 a share because things are going well. Companies with bad balance sheets, outmoded technology or failed Phase III drug trials are not bargains. You never want luck or hope to be part of your investing equation. Always stick with the fundamentals.

Diversify, Diversify

Cramer's next rule for investors is another oldie but goodie: "Diversification is the only free lunch."

Cramer said this rule runs contrary to our natural instincts. When Tesla Motors (TSLA - Get Report) shares are roaring, we want to be 100% invested in Tesla Motors, which is not a balanced portfolio.

Diversification plays out in many ways, Cramer continued. Investors usually know it's bad to have all their money in one stock. But the same rule applies for having too much invested in one sector or, worse, your employer. Far too many former employees of Enron and Nortel put their faith in their employers and lost everything.

So while you will undoubtedly hate yourself for being stuck with defensive stocks when you see the biotech stocks or the cloud computing names roaring to new heights day after after, Cramer said when the markets get clobbered later on you'll realize the wisdom of diversifying.

Don't Go It Alone

Cramer's final rule for investors was simply this: Be able to explain your stock picks to someone else.

One of the worst things to happen to stock picking, in Cramer's eyes, has been the Internet. Why? Because it removed one of the most important brakes in the process -- talking to someone. Buying stocks has become a solitary affair, he said.

One way to cut down on investing mistakes is to force yourself to articulate why you would like to buy something. Can you explain what the company does? What are its main products? What makes them unique? These are all questions investors should be able to answer to a friend, colleague or family member.

There are also questions of timing. Is there a reason you want to buy now? Is now the best time to buy? Should you wait until the stock comes down a little more? More good questions.

Finally, Cramer said investors need to consider their "edge." What do they know about this stock that others don't? Do you like this stock more than others you already own? Is this investment worth selling something else to replace it?

This last question is of particular importance, Cramer said. Investors are not mutual funds. It's impossible to have dozens of good ideas all at once. You should always subtract a stock before adding one to your portfolio.

"Don't short-circuit the process," Cramer concluded. Look for the reasons not to own a stock before you buy it because after you buy it those reasons will certainly come to your attention.
