Google Inc (GOOG), Netflix, Inc. (NFLX): What Mega-Manager Would Like These Stocks?

“Unfortunately, most aspiring traders find out far too late that the act of trading is 20% intellectual and 80% psychological,” says Michael Martin in The Inner Voice of Trading. For this very reason, it’s crucial that every individual investor finds a system that is compatible with his or her psychological makeup. Of all the investment advice out there, here are two particularly Foolish philosophies for long-term investors.

Value investing

An investment that could fit this investing style well is Google Inc (NASDAQ:GOOG). Google Inc (NASDAQ:GOOG ) is clearly the world’s leader in online search, with more than 60% market share (no other competitor has more than 10% market share). While traffic acquisition costs are on the rise as the company transitions to a more competitive mobile environment (7.9% of revenues in Google Inc (NASDAQ:GOOG )’s first-quarter results compared to 6.4% in the year-ago quarter), secular growth trends in digital advertising should continue to drive EPS growth. At 26 times earnings, the company is reasonably priced.Famed value investors Warren Buffett and Charlie Munger believe the best way to identify this value is to look for excellent businesses trading at reasonable prices and buy them with the intention of holding them over the long haul.The term “value investing” is often used in different ways, suffocating its meaning. But it’s actually really simple. Charlie Munger, in his typical bluntness, sums it up best: “All intelligent investing is value investing — acquiring more than you are paying for.” Investment advice doesn’t get any plainer than that.

Growth investing

What kind of crazy investment advice tells you to ignore price? This kind.

The premise goes like this: Growth investments face such incredible growth opportunities that considering valuation metrics will do more harm than good, because many of these industry disrupters will never trade at sensible valuations.

Growth investors aren’t looking for good investments, they look for outstanding businesses. As Fisher said, “I don’t want a lot of good investments; I want a few outstanding ones.”
