Conclusion
So, what does all of this backtesting tell us?
It was almost impossible to lose money on the stockmarket if you held stock from 2012-2014; the market performed extremely well during that time, and as long as you had a diversified portfolio, it would perform pretty well. (Although depending on your stock picks it might not outperform the market as a whole).
Some of the results of the performance and backtesting seem to be unintuitive, certainly when looked at over the longer term. For example:
- High P/E securities performed well, even though they weren’t returning much money in the form of dividends. This probably means that investors were more focussed on capital, rather than dividend growth.
- Companies that didn’t supply a high EBITDA (profit) still did well over the medium to long term, probably based on speculation about future growth. Many of these businesses were pharmaceuticals or alternative energy businesses that might not see an ROI for several years.
- A combination of high beta stocks with high P/E ratios can generate good returns, again probably based on speculation. There may be losses in the short term though.
Other points
- Low beta ratings definitely equal more predictable stocks; the low beta rating backtests were some of the few that did not provide negative returns at any point.
- Stocks with the larger market caps mirrored the overall performance of the stockmarket very well; this is to be expected, since they make up a significant portion of that market.
- Low market cap securities and high beta ranked securities are best avoided as they can create significant losses over the short term.
- Good PEG ratings (between 0.1 and 1) correlate very strongly with good performance.
- MMAV and LMAV are good predictors of growth stocks; unfortunately I did not have historic MAV data to test this with, but it is definitely worth incorporating into future algos.
Next steps
In another post, I will take the most positive correlation factors for growth and try to develop a group of stocks that can deliver good returns. Thanks for reading this thread and I am grateful for any comments.
