My first career after uni was as a stock broker, but I soon learnt that it was not for me and moved over to the investment analysis on the buy side, but left that for a broader career in corporate finance. I’ve owned stocks and bonds for most of my working life and learnt that if you’re going to be in the market diligence and a long term view and patience are essential along with a healthy respect for the downside. I’m fortunate to have two defined benefit/final salary pension schemes, but I’ve still taken a conservative approach to my investments. At present my portfolio is split 50/50 between cash + fixed income/common stock. The portfolio is diversified by geography, currency and industry, but all in high quality issuers with sound fundamentals, strong balance sheets and top tier management. Nevertheless, the recent stock market crash has negatively affected my portfolio, but not disastrously. I take the long view and don’t worry about the day-to-day gyrations of the market. Because i have a good cash cushion and solid pension income I have not had to sell any of my stocks, but I have done some judicious culling of my weaker holdings for tax loss purposes. Common mistakes include panic selling into a falling market and/or not clearly understanding the difference between investing and gambling. Also, trying to time the market is a dupes game: what matters is not market timing, but time in the market. Bottom line, if you have a well structured and diversified portfolio property aligned with your risk tolerance and financial needs and objectives you should be able to ride out the current storm. Just ignore all the market noise and keep your eye on the long term, which for me is the next 5-10 years. And before I forget, don’t be greedy: pigs get fat, but hogs get slaughtered. This is just my view as an informed layman who’s spent the last 50 years trying to build a secure financial future for my family. I should note also that I have an independent fee-only financial advisor and an independent fee-only portfolio manager, both of whom I discuss my finances and investments with on a regular basis.
