Once they told me that the biggest difference between good investors and bad investors is the amount of capital they can move. Good investors have large capitals that can absorb market drops and then rise again. Bad investors are wiped out by small fluctuations. In other words, what works for who drives large funds will hardly work as well for the average bloke. Keep it in mind whatever you read.

Assuming that you wouldn't ask here if you had large capitals, I recommend you to keep it simple and invest in funds with low commissions (like ETFs) tracking something like companies with very solid brands that will never go out of business (like Coca Cola). With 4/5 points of return above the inflation over 10/20 years you'll have good results.

If you feel lucky, put 5-10% in something high risk high reward and be prepared to lose half of it. Read whatever you find to understand the jargon (e.g. what's a "synthetic" ETF) and you should be fine with those simple tools. Don't forget to study the fiscal aspects, especially in regards of dividends and capital gain: often there are two version of the same fund, but one is more "fiscally efficient". Last advice: keep aside cash for emergencies because you don't want to sell your positions in the middle of a crisis.

I'm not a fan and sometimes they are full of BS, but you can check forums on FIRA (for early retirement).
