倉位交易法-打低持倉成本

就我目前的交易探索,我發現不管是日衝還是短線,無論你的技巧如何精確,影響打低持倉成本效果的最主要因素還是: 倉位! 也就是你究竟用多大比例的倉位去進行高拋低吸和低吸高拋的活動!!!
這個很好理解,如果每次隻用10%的倉位去倒騰,無論你怎麽精確巧妙,比如抓了10%的日漲幅,對最後結果的影響隻有1%.但是用50%的倉位,隻要抓了5%,最後成本價就降了2.5%.更進一步,90%的倉位倒騰,抓日跌幅的4%,成本下降3.6%, 這個效果就很顯著了.
這個不是什麽吹牛或者空穴來風,我以前就這樣幹過,用50%倉位的時候,兩三把倒騰就把成本降到比我第一次買還低的前所未有的低價.用95%倉位的時候,一日之間,就把該股的持倉成本下降了3%.這個3%的效果我以前按纏論10%或者5%倉位的時候,要用1個月才做得到!
為何以前沒將這種方法擴展,主要還是心態問題,散戶怕踏空,我也一樣,對於一些看得見的跌勢,缺乏足夠的耐心,因為的確有些賣後就漲的例子,所以總是被一些莫名的願望和夢想驅使,怕踏空,不敢用高倉位去做空.其實漲了就跌是自然規律,對規律僅僅停留在認識的水平隻上,和膽大到用這個規律去一意孤行絕對是兩個不同的概念和水平!

所以,炒股炒到後來,不隻是技術,而是心態!
目前的策略:提高倉位交易比例至30-90%,現金比例20%.這裏麵,日衝還是顯示出了它無與倫比的優越性.因為開盤價很容易受莊家和外界消息以及大勢的影響.這對SWING TRADING 是非常不利的,也就是SWING TRADING 的不可控因素太多.但日衝就不同,幾乎就是比較純粹的技術,這個是個人水平比較容易能控製的部分.也就是賺確定無疑的鈔票還得日衝好啊!

讓我們看看這個經典的成功案例:
------------------------------------------------------------------------

今天買、明天賣;零買囤賣,整買零賣的手法逐個露麵,遊資導演了又一幕熱炒“洗具”。    
三峽水利2011/1月26日股價第一次漲停,“今天買明天賣”主力首次出現,銀河證券佛山南海桂平西路營業部買入1631萬元,次日高開衝高回落,賣出1728萬元,獲利了結出局。    
東方證券蘇州臨頓路營業部是零賣囤賣的代表,1月26日至28日三天1981萬元,等到2月9日,一天賣出2327萬元。
國盛證券撫州贛東大道營業部則是整買零賣,2月9日買入2432萬元,11日、14日分別賣出1543萬元、1082萬元。    
炒作晉億實業營業部同樣參與三峽水利,2月1日股價漲停,溫嶺東輝北路營業部開始露麵,買入三峽水利2578萬元,把對高鐵龍頭的持續買入手段再次應用,下一個交易日的2月9日再度買入2304萬元,同時賣出2625萬元,這兩個交易日都是漲停,很可能是股價稍微低開時未來仍舊看漲,繼續買入了2304萬元,等到股價漲停,賣出了前一天所買股票,當天做了“T+0”交易,手中股票倉位沒變,但已經降低了成本,當天買入的這些股票在2月11日賣掉絕大部分。

---------------------------------------------------------------------------
這才上真正的"倉位交易",也就是Position trading. 至於網上說的,甚至一些交易公司裏科普的Position trading概念,我認為都是瞎扯!
他們是這麽說的:
Position Trading:

Position trading, also known as 'trend trading', can best be described as a 'buy and hold' method. Positions can be open for a few days, a few weeks, a few months or longer. They are also held during periods of minor retracement with the expectation that they will eventually continue trending in the desired direction.
Pros:
- The most forgiving type of trading - small mistakes are more easily absorbed in market movement and the size of your eventual profit.
- The easiest to learn. It is estimated that up to 25% of position traders learn to become profitable.
- Less stressful than intraday or swing trading.
- Easier to become successful with smaller startup capital.
- Much easier to predict the market as in general you will be following the overall trend.
- In general position trading is the most profitable.
- Less time consuming than day trading.

Cons:
- Compounding has a lot less effect on profit than both intraday and swing trading.
- Because positions can be highly leveraged and trades remain open for extended periods of time, unable to reap consistent benefits of interest.
- There is inherent risk in keeping positions open over night. It is quite possible for drastic changes to occur in the market while you sleep.
- Money can be tied up for an extended period of time. This can prevent entry into new positions as they arise.
- Because of the length of time involved in position trading, traders can experience significant drawdown with the expectation that it will turn around and start trending back in the desired direction. Psychologically this can have a very negative effect.
