The Six No To Stock Investment

These are my 6 Golden Rules after learning from the mistakes of others over the last decade.

1. No airlines (Highly-competitive industry, capex intensive)
2. No S-Chips (Higher-than-usual rate of corporate scandals/frauds) 
3. No penny stocks (Usually not market leaders, earnings tend to be volatile)
4. No O&G stocks (Highly cyclical, dependent on oil price, 2015-2016 oil crisis)
5. No shipping stocks (Dependent on global trade, over-capacity)
6. No utilities/infrastructure (Look at Hyflux's fall from grace)

Thanks Dividend Warrior, that I learned from you.
