Fools were out and about this week in an investing world jam-packed with actions and ideas. Here are three articles you might find useful as you decide how to invest your money.

5 Stocks to Buy Before Apple
Apple (Nasdaq: AAPL)! Must we say more? Oh, OK.

"Too many investors get excited and jump into a stock without comparing and contrasting against other possibilities," writes Fool editor and writer Anand Chokkavelu. "Before you buy shares in the iPhone/iPad/iMac-maker Apple, let me give you one (hopefully) compelling reason to consider one of these five other stocks."

Click to the article to see what Anand has to say about stocks that might offer you more than Apple can. For instance, find out why he thinks the compelling reason to buy NVIDIA (Nasdaq: NVDA) is "bang for your buck."

3 Stocks to Play Biotech
Do you curse the drug companies every time you open your wallet at the pharmacy? Want to turn that frown upside-down? You could consider investing in biotech companies.

"[A] science background isn't really required to invest successfully here," notes Fool editor and writer Jim Mueller. "Instead, an appreciation for the binary events, the partnerships, and the size of the pipeline that can be turned into revenue will go a long ways toward putting you onto the road to success."

Click to the article for specific advice on what to look for when evaluating biotech stocks. Jim also selected three companies worth your attention: Keryx Biopharmaceuticals (Nasdaq: KERX), MannKind (Nasdaq: MNKD), and Immunomedics (Nasdaq: IMMU).

China's Best-Kept Secret (Nasdaq: SOHU), which makes money from online gaming and online advertising in China, often flies beneath investors' radar. Longtime Fool contributor Rick Munarriz checked out the company's earnings report and found something interesting.

"[T]he real head-turning aspect of Sohu's report is that its Internet brand advertising business grew more quickly than its Changyou-driven gaming efforts," Rick wrote. "Sohu's $53.5 million in brand advertising is just 36% of its revenue mix. Online gaming commands a thicker 53% slice. However, [brand advertising is] certainly a significant part of Sohu's business, and a one-way ticket to higher multiples, chunkier share prices, and a large, attentive audience the next time an earnings report kicks out."

It pays to look beyond the big names that everyone knows about, such as search engine and online gamer Shanda Games in China.
