If the fundamentals of a business are good, we would invest in the business if we could, wouldn't we? If the share price should see a decline but the fundamentals of the business remained intact, we should increase our investment in the business if we could, shouldn't we? I am trying to make 2 points here: 1. Declining share prices give us an opportunity to buy more shares cheaper. 2. We should always have a war chest ready to take advantage of opportunities. People who do not know what they are investing in or who have invested in bad businesses might worry. People who do not have a war chest ready might feel regret. Do the right things, don't worry, don't regret......
