From :Why not invest your assets in the companies you really like? As Mae West said, ‘Too much of a good thing can be wonderful.” — Warren Buffett
For most of us, it’s easier to understand a business or product we encounter on a regular basis. Investing in what you know allows you to more easily place value on the stock and stay informed on industry trends. If you don’t understand what the company does or how it makes money, how will you be able to manage your investment? (When it dips 50%, would you hold on?)
Finding companies you know is only the beginning; the circle of competence is only meant to help you stay within your arena of expertise. Once you have generated a list of the companies you understand, the next step should be conducting an analysis of the financials. Don’t worry — you don’t have to be a finance whiz to understand the basics of the stock market. Berkshire Hathaway’s investment philosophy is surprisingly simple: The company should have consistent earning power, good return on equity, capable management and be sensibly priced. Investing is less about the stock price and more about the value of the business — is it a good one?
Successful investing is more about learning over time and slowly expanding your circle of competence. For now, stick with what you know and focus on the long term..
