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

"Superlative" Stocks to Avoid
In addition to a calculator, investors looking for stocks to research should keep highlighters handy. They're good for marking up the "best" and "worst" lists that make the rounds. Use yellow to highlight the companies you're interested in; use blue for the ones you want to avoid.

Speaking of companies you might want to avoid: Fool analyst Alyce Lomax brought us the news that BP (NYSE: BP) beat out Bank of America (NYSE: BAC) to be The Worst Company in America in a listing compiled by The Consumerist.

"When companies stir up increasing amounts of ire among the customers on whose patronage they depend for survival, investors should take notice," Alyce wrote. "One way or another, negative consumer sentiment will almost always erode sales growth over the long haul."

See the article for Alyce's full rundown on "superlative" stocks to avoid.

7 Stocks for Sky-High Oil
At an average of $3.88 per gallon, gasoline was up almost $0.04 from the previous week and up more than a dollar from a year ago, according to data released Monday by the U.S. Energy Information Administration. The costs that make up the pump price are crude oil (68%), refining (13%), distribution and marketing (7%), and taxes (12%), according to the administration.

Fool contributor Adam J. Crawford brought the good news that "with the right investment, you can actually profit from high gas prices." You could put your money into a company such as Suncor Energy (NYSE: SU), which mines for oil in tar sands, for example. Adam also casts his gaze on natural gas companies, where, for instance, Range Resources (NYSE: RRC) "potentially holds enough natural gas reserves to meet a whole year's worth of U.S. consumption."

Check out the article for all of Adam's insight on profiting from high oil prices.

Why These Stocks Will Last Forever
"[T]here's a key element that any long-lived company manages to master," Fool editor and writer Dan Caplinger wrote this week. "In order to stay relevant throughout the decades, every company must keep innovating."

Taking a look back, Dan talks about companies, including IBM and Coca-Cola, that stayed strong by evolving to take advantage of changes in the marketplace.

Of course, what investors want to know is which companies will be the stalwarts of tomorrow. Read the article to find out why Dan thinks Amazon.com (Nasdaq: AMZN), priceline.com (Nasdaq: PCLN), and Las Vegas Sands (NYSE: LVS) are exhibiting the necessary innovation.
