Jim Cramer told Wednesday's first caller to his "RealMoney" radio show that Panera Bread ( PNRA) reported a stellar quarter but that it "committed the unpardonable sin of saying it will not do as well in the future." However, Cramer said that this might not be an entirely bad thing. The downbeat guidance will cause analysts to downgrade the stock, which will reset expectations for the company lower. There comes a time when we have to recognize that sometimes when a company says great things and then says that expectations are too high, the company is just telling Wall Street to not get ahead of the story. The company is doing fine, he said, but it just doesn't want anyone to believe that it's doing better than it is. He said that the stock will churn until it reports again next quarter, when it is likely to meet the new lowered expectations. Then the stock should run higher. Cramer said he would wait a month for the market to fully digest the screw-up, and then he would start building a position. Cramer said that he went against Wall Street by buying Nabors Industries ( NBR) for his charitable trust Action Alerts PLUS . Even if Wall Street hates cyclical plays, he said that this stock is still good. He told another caller that Chesapeake ( CHK) is a driller that's a pure play on natural gas. Chesapeake is the "best in show" and should be held because natural gas prices should rise at some point. A caller wanted to know how many shares a person should own to be in the game. Cramer said that it's not a matter of shares, but a matter of how much money a person invests. He believes that an investor should hold at least $5,000, and preferably $10,000, in the stock market. This is the amount of money he feels is necessary to be diversified. The amount of shares a person owns depends on the price of the share. If person has $10,000 in the market and invests in a stock that costs $10,000 a share, that person will only own one share. If the stock costs $10 a share, then the person will own 1,000 shares. Cramer said that companies including Wynn Resorts ( WYNN), Urban Outfitters ( URBN) and Amylin ( AMLN) are priced to perfection and that investors should be very wary of these stocks. He said that Sears ( SHLD), the third largest retailer, is a stock to own for the long term. He owns it for Action Alerts PLUS . He also recommended Amgen ( AMGN) and Apple ( AAPL).
