Average Down and Risk Control (Don't bet the house)
Are you a value investor? Take the Apple test
- Don't bet the house: No matter how confident you are in your value assessment, don't go overboard and invest a disproportionate amount of your portfolio in Apple. This is not just about you being right on the value but also about the market coming around to your point of view, and that is not in your control or mine; betting more than 10% of your portfolio on this stock strikes me as foolhardy.
- Don't double down (Dollar averaging): I have never been a fan of dollar averaging, which not only muddies the water about when/how much you invested in a stock but results in increasing your bets as the market goes against you. Take a stand against the market but do not make this an ego trip, where admitting that you are wrong becomes impossible to do. Thus, while I feel more confident now that the stock is under valued than I was a week ago when I bought the stock for $500, I don't plan to buy more shares.
