Don’t waste a crisis!
In this context I mean, that an investor should use market volatility to improve their portfolio. As I write I realise this can have several definitions. I’ll refer to two:
1) Your position today in £££ value is better than if you had done nothing.
2) Your portfolio has a better balance with dead wood removed and good growth opportunities added.
Both are important to me, but at this point only the first can be measured. Today the second is subjective but can be measured later. Therefore, I’ll focus here on the first.
Why?
I consider myself a serious and successful investor. I’ve been investing in individual stocks for decades and expect to continue for several more decades. I like to assess my abilities with a view to improving my investment decisions, but to do that effectively I need good records and analytical tools. One part of that process is to assess my decisions in extreme periods of volatility because I’ve found that the decisions I make in those periods have the greatest impact over the longer term.
However, if the measurement is only made at the end of the ‘crisis’, lessons learnt can only be used in the next crisis, which may be 10 years away. Measuring at this stage in the current crisis gives me an opportunity to review my decisions while the current opportunity persists.
How?
Very simple. I took the 1st March 2020 as my reference point (choose your own), loaded my portfolio for that date and today’s into a spreadsheet, then made adjustments to the 1st March position to reflect current prices, cash movements (in or out), and dividends paid. Check you get your additions and subtraction right and get the two big final numbers the correct side of the subtraction. In the final sum I saw mine as negative, before realising I’d made a mistake – phew!
Conclusion?
To be clear, I’m not saying my portfolio is ahead of the 1st March position – it isn't – only that I’m in a better position than if I’d sat on my hands.
The biggest surprise for me was how small my overall adjustments were. Although, I’d totally closed some positions, opened others, and adjusted the stake level in most, it appears there were many more trades performed in my head than actually enacted. So, not wanting to waste a crisis I’m doubling down on those decisions that have worked.
As a rule I don’t comment on my trades or holdings so in the same vein I don’t propose this as a competition. Just an exercise that might be of interest.
