Hello scsl,
Firstly, no one is likely to give you financial advice on what MFS is likely to do, since this would contravene the new financial reforms under the auspices of ASIC. Having said this though, if you want to talk technical analysis concepts generically, perhaps this would be a more appropriate way to approach your question. (Please understand that the new reforms are quite stringent, hence the need for formality here).
Secondly, I would argue that “Technical Analysis” is an art, and not a science (although it can involve science/logic, and some would argue differently – especially if you’re into moving averages and oscillators and other such “lagging indicators”).
Interpreting charts is a skill which every individual will perceive uniquely. Put 10 traders in a room, and you’ll have 10 different perspectives. Some may agree on one thing, and not another. Sure, there are schools of technical analysis thought that use agreed concepts, but how these are applied can range widely from person to person (for example get a room full of Elliott Wave experts to label waves and see what happens).
Ok, head and shoulder (H&S) patterns. Ultimately I think they are bunk, but can have limited use in concert with other patterns (but that’s my opinion, and others swear by it). Sometimes they work, and sometimes they don’t. The theory is that the underlying will move at least the distance from the neckline to the top in the opposite direction - i.e. pull back the same distance from the neckline to the top projected down (or vice versa for an inverted H&S).
Whenever I see a lower high, I recognise that there is some risk of downside price action. The real art is in looking at the whole pattern of trend, in daily weekly and monthly charts (and intraday if you’re using that time frame).
You can interpret a whole host of technical concepts like - looking for base or topping patterns, examining wave structure, looking at price extensions/retracements, interpreting bars and volume. All of these elements can give you clues to make forecasts in time and price. Of course the time element is a little more controversial, so we won’t go into that here. The core point is though that anything can happen in the market, and every moment is unique (ala Mark Douglas’ “Trading in the Zone”).
If you ask for technical analysis texts in this forum, you will receive a deluge of conflicting works. All the technical traders I know have spent years studying various approaches and each have developed their own special brand of analysis based on their personal experience and preferences. You’ll get Elliott Wave enthusiasts (I do subscribe to this school), moving average/oscillators backtesters/mechanical traders, candle stick traders, etc (and maybe even the odd Gann player).
So, you have the whole constellation of technical approaches to explore. I will give you one piece of advice though: Develop confidence in yourself, and trade your own knowledge!
