NEW YORK ( Stockpickr) -- In addition to Stockpickr's popular Professional Portfolios, which list the holdings of many of the top investors and funds, such as Warren Buffett and Paulson & Co., the site also hosts user-generated portfolios. This feature allows Stockpickr members to group stocks together in portfolios so they can easily see where each stock is trading and view fundamentals such as market cap, average trading volume and 52-week highs and lows. Users can also elect to track their portfolios and measure the overall performance of a group of stocks over time.

Anyone can join Stockpickr and start creating portfolios, whether they be of stocks actually owned, a watch list of stocks or a group of stocks related by a certain theme. Regularly, we also group together the stocks that our colleagues over at TheStreet are talking about.

Over the past week on TheStreet, our colleagues have been talking about large-cap stocks with substantial sales growth, stocks for the second half of the year and more. Here are some of the highlights.

10 Large-Caps With Fastest Sales Growth: TheStreet's Jake Lynch suggests a shield for investors concerned about a double-dip: "large-cap companies that have global reach and ample cash to withstand a slowdown." For example, on his list of 10 companies that have increased sales at an annualized rate of at least 34% over the past three years is Celgene ( CELG), which has boosted sales by 42% since 2007 and increased profit by 44% in the first quarter and revenue by 31%. The 10 Large-Caps With Fastest Sales Growth portfolio also includes Freeport-McMoRan ( FCX).

5 Dow Stocks Likely to Rise After Earnings: Robert Holmes notes a pattern of some Dow stocks historically exhibiting better post-earnings performance than others and narrows down the five that have "notched the biggest gains in the day after posting quarterly numbers in July and August over the past five years." For example, Hewlett-Packard ( HPQ) has averaged a 4.6% gain over the past five years on the day following its fiscal third-quarter reports, and Cisco's ( CSCO) average gain was 4.1% over the past five fourth-quarter day-afters. The 5 Dow Stocks Likely to Rise After Earnings portfolio also includes JPMorgan ( JPM).

6 Stocks for the Last 6 Months of 2010: InvestorPlace assured readers that buy-and-hold investing wasn't dead, in spite of the first half of 2010's wild ride, and that "low-risk, stable stocks," such as Microsoft ( MSFT) and McDonald's ( MCD), can act as an insulation to your current portfolio holdings during the second half of the year. The > 6 Stocks for the Last 6 Months of 2010 portfolio also includes United Technologies ( UTX).

9 Famous Tech Stocks to Sell Now: Louis Navellier InvestorPlace predicted good things for the small-cap tech world but said some of the bigger-name stocks could be running into trouble in the coming weeks. On his list of tech stocks to unload before then is Nokia ( NOK), whose "stock has been struggling all year" and Research In Motion ( RIMM), which with its BlackBerry has taken on the role of second fiddle to the iPhone and Andriod devices. The 9 Famous Tech Stocks to Sell Now portfolio also includes Dell ( DELL).

10 Large-Caps With Highest Dividend Yields: Jake Lynch offers up a list of the 10 highest-yielding stocks in the S&P 500, which he says "offer big dividends and a margin of safety because of their size." Topping his list was Frontier Communications ( FTR), which offers a more-than-10% dividend and "Trades at a premium to telecom peers based on projected earnings and book value." The 10 Large-Caps With Highest Dividend Yields portfolio also includes AT&T ( T) and Altria ( MO).
