So where should an investor's dollar go: large-cap stocks, mid-caps, or small-caps? How about all three? That's what Ken Kam advises.

His all-cap 4-star Marketocracy Masters 100 went up 7.62 percent in the second quarter, and it's up an average of 11.22 percent per year over the last three years.

"We don't make big best on anything," Kam told CNBC. "We like to have a diversified portfolio that can still outperform the market...we have 198 stocks right now, and that's on the low side."

Recommendations:

So which of those 198 stocks occupies the largest space in Kam's portfolio?

"Right now, the single largest position, and probably the best performer for the last quarter is Elan," he said. "It's about 6- 1/2 percent of the portfolio."

He also likes Bank of America and MasterCard.

"We like that stock," he said of MasterCard. "It tends to get sold off when the financials sell off, but MasterCard is really not in the same industry...they get paid every time you use your card, but they do not have any credit risk."

Kam says it's important to have money in oil.

"The supply and demand for oil has been out of balance for the last four years, and we've seen the impact of that in the oil price," he explained. "The value of...oil reserves is increasing faster than the revenues and earnings for most of these companies, particularly Occidental (Petroleum), which is our favorite oil and gas stock. They have the prime leases in Libya."

For a long time, shares of casino gaming companies were best bets. Those days are over, but there's still money to be made in some selected stocks, according to Jake Fuller.

"If you look historically...gaming did hold up very well in the past couple of pullbacks," the Thomas Weisel Partners hospitality analyst told CNBC.

But things are different now. Gambling has proliferated, and riverboat casinos, Native American casinos, and horse tracks with slot machines have diluted the monopoly Atlantic City and Las Vegas once enjoyed.

"A bigger factor is, it's not just gambling any more," Fuller added. "Most of the big casino companies derive over half of their revenue from rooms, from restaurants, from retail, from entertainment, things that are more discretionary, more susceptible to the consumer pullback."

Recommendations:

"The names we are recommending are, specifically, Ameristar and Pinnacle," he said. "They trade at lower valuations; revenue should be a little less cyclical."

Pans:

Geography plays a role in the stocks Fuller thinks investors should avoid.

"The big-cap names, companies like Las Vegas Sands, MGM and Wynn, (have) a lot of exposure to markets like Las Vegas," he said. "Las Vegas, you're going to see a lot of downward pressure in the short term here."

Jon Hilsenrath, money and investing news editor at the The Wall Street Journal, offered CNBC his "5 for 5": the five stocks you must watch this week.

Alcoa: The mining giant kicks off earnings Tuesday -- but don't expect to see a boost from global commodities hunger.

"Aluminum prices have topped out," explains Hilsenrath, and the metal is "highly energy intensive to make."

General Electric: The corporate parent of CNBC reports later this week, amid the news that GE's NBC Universal unit will buy the Weather Channel .

"It's a good time to announce [anything] that will get investors excited," he says. With its 1-year performance down 30 percent, GE "can't afford to disappoint."

Marriott International: The hotelier chain reports second-quarter earnings before the bell Thursday. Hilsenrath cites a "classic hotel-sector cycle" with too many rooms put on the market -- and much talk of industry consolidation.

Hilsenrath also suggests keeping an eye on news publisher Washington Post Co. and video game maker Activision.

It may be time to stop going offshore, but where are the opportunities in America?

"The emerging markets are slowing down," Noah Blackstein of Dynamic Mutual Funds told CNBC.

"Everyone here keeps talking about the strong growth in China and India, but...those stock markets...India's down 40-plus percent this year, China's down 60 off the high, so I think those markets are slowing down," he said. "The key to the market is oil prices...it's very difficult to see the market growing with $145 oil."

Recommendations:

But Blackstein still sees an upside in technology stocks.

"I think there's some secular growth in technology," he said. "Google is obviously one; the closing of the DoubleClick acquisition...obviously doubles their market potential."

There's another tech stock that he likes even more.

"I like Apple here a lot," he said. "Apple really got hammered here in January; it's come back to the $170 mark, and I think you're just gearing up for this next platform, this next leg of growth, really globally with the iPhone."

Disclosure:

Blackstein owns shares of Google; disclosure information about Apple was not immediately available.

The options market is signaling that there may be trouble ahead for regional banks, according to one expert.

"We're looking for more volatile downside from the regional banks," said Rebecca Darst of Interactive Brokers on CNBC's "Squawk Box" Monday. "This is perhaps not going to come as any great revelation to people who have been following the financials for some time, but it's interesting nonetheless, because we're looking for continued erosion below the lows."

Environmental and energy companies in Japan look very strong, Makiko Zuercher-Hosaka, fund manager for Japanese equities at Clariden Leu said Monday.

The week was a mixed bag of economic and market news, most of it on the negative side. Oil prices continued to hit record highs, the market officially entered bear territory and the European Central Bank socked it to the U.S. by raising rates a quarter-point. Despite all of this, CNBC guests found bright spots in steel, financials, tech and international stocks.

Monday:

Monday ended the market’s worst monthly decline in nearly six years, with financials leading the plummet. Shares of Lehman Brothers tumbled more than 10 percent on speculation that the bank could be forced to sell itself. Oil prices topped $143 a barrel for the first time.

Mark Parr, of Keybanc Capital Markets, said steel stocks are a very fertile place for solid capital gains over the next 12 months. He liked U.S. Steel , Nucor , Steel Dynamics , Reliance Steel and Olympic Steel .

The European telecom sector could be a good place for investors to park their cash, particularly Deutsche Telekom and UK's Vodafone, James Bevan, chief investment officer at CCLA Investment Management, told CNBC Friday.

Shares of leading mobile handset maker Nokia have fallen nearly 40 percent so far this year, producing a great buying opportunity for a still-growing tech company. And the commodities boom means agriculture and energy are also still good places to invest, according to strategist Wouter Weijand.

While Nokia's sales growth in the West has declined, Nokia still has an increasing demand for mobile phones from emerging markets like China and India, Weijand, chief investment officer of high income equity at Fortis Investments, told "Worldwide Exchange."

"(Nokia is) trading like a value stock but still offering longer-term growth. It is a great franchise and they have no debt at all on their balance sheet," he said.

Australian fertilizer distributor Incitex Pivot is also a buying opportunity, Weijand said.

Warren Myers, a trader at Walter J. Dowd, says "oil can determine different sectors and companies" -- but he is hopeful about the tech sector.

Recommendations

IBM – “A name that’s never mentioned anymore, but has been acting quite well, at least for the last year or so.”
