For better or worse, Peter Lynch is the "buy what you know" guru.
Even though he's said he didn't mean that exactly, "buy what you know" is an incomplete guide to beating the market. It suggests that some of your best investing ideas will come by snapping up shares of companies behind your favorite products or by trolling the mall. And when I first read it as a twentysomething investor, I embraced the simple notion of acquiring the familiar.
But it's not so simple.
The other half of "buy what you know"
The problem is that "buying what you know" is just the first step to beating the market. Once you take it up a notch -- going from One Up on Wall Street to what I will call Two Up on Wall Street -- you will realize that the second logical step is even more important.
That second step? The missing ingredient from Lynch's once tantalizing investing recipe?
Buy what they don't know.
Calling off the Lynch mob
After all, I can live my life singing the praises of Apple
So it's not necessarily about buying what you know. It's ultimately about buying what they don't know.
Some of my favorite investments -- and, I bet, many of yours -- have been companies that grew in popularity after they camped out in your portfolio. I bought Jones Soda
The pop world can use an edgy disruptor. The established titans have the personality of a thimble. In the meantime, I'll keep downing the mainstream and seasonally offbeat flavors in the Jones Soda family. I'm buying what the rest of the market doesn't know, and it's sweetened by cane sugar.
Zig before they even think of zagging
As a member of the Rule Breakers newsletter team, I try to spot emerging trends early to try to profit from being early to the party. David Gardner's newsletter is all about buying what they do not know.
Well, it hasn't happened yet. More important, Blue Nile has gone on to blow away Wall Street's expectations in every quarter but one since going public nearly four years ago. I knew about Blue Nile when David Gardner recommended it. The real kicker is that most investors didn't -- and still don't -- know it.
Buy what you know better
When you invest, go to the mall; ponder the contents of your cupboard; question why you chose one burger joint over the other. And when you unlock that desire to be inquisitive about equities, also figure out what you know -- and what you see -- before the rest of the market.
