股價低買高賣的準則

一、前言
股市競爭比戰場還激烈,要買什麼股票?要賣什麼股票?必須要有一一致性、完備性且是決定性的公設(postulate)或公理(axiom)做為股市戰場的作戰準則 --- 低買高賣。

二、股價低買高賣的準則
股價低於內在價值時就堅決分批買入,以實現“低買”作戰準則;反過來,股價遠高於內在價值時,就應該分批賣出股票,以實現“高賣”作戰準則。(確定你持股的股價比(P/X)在本blog表頭分配圖的哪一區間,及其臨界點)

三、買什麼股票的作戰準則
當股價 / 內在價值處於收歛,其趨近於臨界值域下限時是最佳的買入時價區域,也就是:d(P/V) → 0,且d(d(P/V)) > 0 ;

四、賣什麼股票的作戰準則
當股價 / 內在價值處於發散,其趨近於臨界值域上限時是最佳的賣出時價區域,也就是:d(P/V) → 0,且d(d(P/V)) < 0 ;

五、實戰之實證與情報

Why the Stock Markets Are Up ?

Lee Li : 分析Biggs列出4項全球股市在3月份後大漲的原因(請看下文),我歸納這4項原因的主要唯一真正因素是資金動量反轉(─MV=ƒ△I),也就是回流的資金行情發揮效應,蓋因2007秋季起,資金動量就一面倒地往市場外流出(●),直到今年3月份,市場外累積的資金位能已大大於市場內剩餘的資金位能,當時機進入一反轉臨界點,資金衝量產生反轉,使資金動量轉變為由市場外向市場內流入(×),致使現在市場內的資金位能大肆地在增加。
Biggs所舉的第3項原因是我強烈認同的(其他3項原因是可有可無的定性分析),加上龐大的失業大軍,他們已沒有固定的薪資所得,所以很多失業人員冒險拿著錢到股市追高搶購股票,想從股市撈一票,以彌補失業沒有薪水的機會成本,但既然是機會成本,等到資金衝量再一次發生沙漏反轉效應時,手腳慢的人終究將付出成本與代價的。




why are stock markets going up when so many economic numbers are going down?
To understand the rally, recognize that the GDP statistics you are reading are already out of date.

Equity markets around the world are surging in the face of the sickest global economy in more than half a century, a crippled banking
system that needs billions of dollars of equity capital, a flu scare
and house prices that are still falling at a dizzying rate. On April
30, the front page of The New York Times
read ECONOMY SLIDES AT FASTEST RATE SINCE LATE 1950S. That same day, the German finance minister said his country would suffer "the worst recession since the Second World War" and that other European economies were in dire straits.
The declines have been even more severe in Asian economies such as Japan, Korea and Singapore, and most experts are skeptical about the better numbers from China. The "great minds" of the investment world and the most highly regarded economists are preaching gloom and doom and a generation of wealth destruction.

First, recognize that the statistics you are now reading are already out of
date. The U.S. government reported on April 29 that real GDP fell 6.1
percent in the first quarter after a 6.3 percent drop in the fourth
quarter, the steepest six-month decline in 50 years. Yet U.S. stocks
rallied to a new recovery high the same day. Why? Because beginning in
mid-March, there were signs of what Ben Bernanke called "green shoots"
in the real economy, namely that the rate of decline, or the so-called
second derivative, was decelerating. Some investors began to believe
the world economy was bottoming out.

Now those green shoots are budding into foliage. In the last couple of
weeks, there have been signs that the U.S., Germany and Asian economies
are on the verge of not just bottoming, but rebounding. It's beginning
to appear that real GDP growth could be positive in the second half of
the year—maybe even sooner. Leading indicators, including new orders
and the purchasing managers survey, are rising. New home sales, the
best leading indicator of the price of existing homes, seem to be
stabilizing. Historically, the steeper the GDP decline, the stronger
the rebound. Ed Hyman, the most highly regarded Wall Street economist,
is talking about 4 percent real growth in the third quarter.

The second key reason markets are up is that most of the gloomy news that
is on television and the front pages is already discounted in stock
prices. Equity markets are looking ahead, not behind. Remember, this
brutal bear market began in the summer of 2007, when the world still
appeared to be booming. As for the "great minds,"once they become celebrities they are wedded to their views. These newly minted heroes dash off books, and get paid big speaking fees. They become committed to their forecast. This is not just true of bears; it happens in bull markets, too. The point is that it is very hard now for the bears to reverse their position. Only the really good ones will.

The third reason equity markets are rising is the unparalleled amount of cash on the sidelines, which will eventually have to be invested. Money-market-fund cash is at a record 40 percent of the total U.S. market capitalization. Professional sentiment, which we monitor systematically, has risen some in recent weeks, but it is still extremely pessimistic. Major pension funds and endowments—which for decades have automatically sold stocks when they went above a preordained portfolio level, and then bought back into them when they went below the minimum—have suspended automatic buying out of fear. The 25 percent rise in prices we have already experienced puts immense pressure on them to at least get back to their minimums. The pain of missing a bull market is very severe. My guess is they will soon be buyers. We are talking about billions of dollars here.

The fourth reason for the rally is that credit and money markets have
improved dramatically. Spreads on everything from high-grade corporate
credit to junk bonds have narrowed. The three-month interbank lending
rate, which affects so many other rates, has fallen from its recent
high of 4.82 percent (right after Lehman failed) to 1.02 percent. And,
of great importance, a large number of high- and low-grade credit deals
are getting done.

Many analysts call this just a bear-market rally, which has about run its course and should be sold. Instead, I believe this is a cyclical bull market within a broad trading range, which means prices could go up another 10 percent to 20 percent. One signal to do some selling will come when you're hearing about how much better the world is looking on CNBC television and from your friends. Another warning will be when the market no longer goes up on good news. We've still got huge legacy problems. The aftermath of saving the system through massive monetary and fiscal stimulus is bound to be unpleasant. The piper will eventually have to be paid. Using the
S&P 500 as a benchmark, my prediction is that we'll see a broad trading range somewhere between the March lows of 700 and the 2000 and 2007 highs in the area of 1450 to 1500 over the next few years. Be prepared: within this cage there will inevitably be periodic cyclical bull and bear markets to torture us.
