CNBC's Jim Cramer has become more cautious on the market right now and conditions are creating a "nightmare scenario" for just about everyone involved, he said on "Squawk on the Street" Monday.

Traders want to generate some profits with electricity producer Calpine.

OptionMonster's tracking programs detected the purchase of some 1,600 June 21 calls for $0.55 to $0.70. Volume was more than 10 times previous open interest at the strike, indicating that new positions were initiated.

These calls lock in the price where shares can be purchased, letting investors cheaply position for a rally before the end of the week. The contracts can also generate significant leverage, doubling or tripling from even a small gain in the underlying stock.

Wells Fargo has been the strongest and most consistent earnings performer among the "big six" U.S. banks over the past three years, but analysts have differing views on the stock.

Jefferies analyst Ken Usdin on Friday reiterated his buy rating for Wells Fargo, while raising his price target for the shares to $44 from $42, writing in a note to clients, "while the operating and regulatory environment is clearly challenging, revenue diversity and credit/expense leverage should allow the company to grow EPS going forward."

Meanwhile, Sterne Agee analyst Todd Hagerman on Friday downgraded Wells Fargo to a neutral rating from a buy, writing to clients that "although WFC's outlook remains constructive, particularly expense leverage tied to the company's efficiency initiative and legacy servicing/mortgage-related costs, earnings growth is clearly moderating into '14."

Restoration Hardware has unbelievable momentum and is a "terrific company" that is shaking up the retail market for home furniture, CNBC's Jim Cramer said on "Squawk on the Street" Friday.

Intel options were active earlier in the week, and yesterday the buying hit right at the top of CNBC's "Fast Money Halftime Report."

OptionMonster's scanners detected heavy volume in the June 23 calls and the July 25s as traders once again rolled their positions to higher strikes in longer-dated contracts. This time, they sold the June 23s for $1.83 and bought the July 25s for $0.74.

These calls lock in the price where the chip maker's shares can be bought, so they can track movements in the stock price cheaply and leverage any rally. On Tuesday, they rolled up from the June 26s to the July 27s.

Coty opened for trading Thursday, ranking as the third-largest IPO of 2013, and the company's CEO, Michele Scannavini, spoke with CNBC's "Squawk on the Street" about the fragrance maker's strategy as a public company.

Coty shares hit the market at $17.50 and raised about $1 billion for the company, but dropped slightly on its trading debut, despite high interest from investors.

Apple shares may be down 20 percent year to date as investors worry about slowing growth, but two top performing fund managers with different strategies still see reason to own the smartphone maker.

"Given where the stock is priced ... a lot can go wrong before the stock appears overvalued," value fund manager Bill Nygren of Oakmark Fund told the Morningstar Conference in Chicago.

Growth manager Steve Wymer of Fidelity Investments agrees.

The bulls are betting that Select Comfort is getting its mojo back.

The mattress maker was a monster stock between 2009 and 2012, rocketing from under $1 to over $35. It then dropped for the next year, but has been working its way higher since April.

Upside option activity in the name crossed our screens yesterday. OptionMonster's tracking systems detected the purchase of some 3,700 September 25 calls, most of which priced for $1.60. Volume was almost 19 times higher than the strike's previous open interest, indicating that new positions were initiated.

CNBC's Jim Cramer sees two "incredibly" bullish signals for bank stocks: a shrinking number of underwater mortgages and a rising net interest margin. He says that one company in particular may benefit disproportionately: Wells Fargo.

In a report from CoreLogic released Wednesday, there were 9.7 million properties underwater in the U.S. during the first quarter of 2013, down from 10.5 million in the fourth quarter of 2012. A home is considered "underwater" when the underlying value of the property is less than the principal owed on the mortgage.

"To me, Wells Fargo is the single greatest play if you think houses are coming out from underwater," Cramer said Wednesday on "Squawk on the Street," remarking on the company's "ability to take the collateral and make new loans."

There's no question Home Depot, whose shares have soared 190 percent over the past five years, has been one of the best plays in the housing recovery.

When you consider Home Depot has more than doubled the performance of rival Lowe's during that span, there's little debate as to which of the two wins the title for head of household.

However, I have always had a tough time reconciling Home Depot's valuation to that of other leading retailers such as Wal-Mart and Costco. I'm not suggesting the stock lacks value. It's clear the Street has never minded paying a higher multiple for Home Depot. It's worked out very well over the past five years, yes. But how about the next five?
