This documentation is an extension on the strategy of loss aversion and reversion to mean. Its aim is to quantitatively identify the point in time when the effects of mass hysteria resultant from bad news has subsided.
For clearer reading of signals, entry should be done at end of day instead of beginning of day.
Heuristics
- Only consider a purchase if there are funds available for deployment
- Only consider companies with my circle of competence.
- To mitigate intraday noise, only execute orders in the last hour of the trading day. Make sure spreads are narrow.
- Only consider entry if the expected value for mean reversion of the company's industry is above 0.1
- Only consider entry if the expected value for mean reversion of the company's industry is above 0.2
- Large dip is qualified if RSI was below 30
- Only enter when MACD histogram down trend receeds
- Enter at historical support level
- Exit at 5% capital gain
- Stop loss at 2% capital loss
