Sylvain's golden rules

Here are the main rules followed by Sylvain Duport:
- First of all, he considers that the market operators have all information and that the price of a stock reflects the general agreement of the market.
- According to him, the market has three movements corresponding to three units of time which are the short, medium and long-term.
- The market has a memory: resistances and support are predictive of the market evolution.
Resistance: It's the price level at which selling is thought to be strong enough to prevent the price from rising further.
Support: It's the price level at which demand is thought to be strong enough to prevent the price from declining further.
- Volumes of investment are necessary to support stock's value especially with an increase tendency.
- The increase of a stock's value is stronger and more lasting if it is reinforced by the stock market index to which it belongs.
- A tendency is said to be bull, if the last summit is higher than precedent one. (the same reasoning for a bearish tendency)
