How I Invest
I try to invest a bit each month, but find that it is expensive to invest this way due to the commissions that brokers charge you. So, my strategy is to invest once per month, regardless of the day or time, or market condition. I look over my portfolio balance, and find holes to plug or companies to add to. Having a strategy to your portfolio as a whole is more important than how one investment is performing vs. the others.
I want to stay balanced, with about 25-30% invested in Berkshire Hathaway, and the remaining 75% in high growth, visionary, high performing companies. I rebalance this with each purchase, and like to buy 2-3 stocks at a time in order to stay balanced and diversified.
