I find the book a little bit disorganized, I have summarized a few points below:
1. There is one crucial difference between investment and speculation:
Investments throw off cash flow for the benefit of the owners; speculations do not. They return to the owners of speculations depends exclusively on the vagaries of the resale market.
and this coincides with Buffett's view as well, as he once said:
So there’s two types of assets to buy. One is where the asset itself delivers a return to you, such as, you know, rental properties, stocks, a farm. And then there’s assets that you buy where you hope somebody else pays you more later on, but the asset itself doesn’t produce anything. And those are two different games. I regard the second game as speculation.
2. Do not let market price cloud your mind:
If you buy a stock that subsequently rises in price, it is easy to allow the positive feedback provided by Mr. Market to influence your judgment. You may start to believe that the security is worth more than you previously thought and refrain from selling, effectively placing the judgment of Mr. Market above your own. You may even decide to buy more shares of this stock, anticipating Mr. Market's future movements. As long as the price appears to be rising, you may choose to hold, perhaps even ignoring deteriorating business fundamentals or a diminution in underlying value.
Similarly, when the price of a stock declines after its initial purchase, most investors, somewhat naturally, become concerned. They start to worry that Mr. Market may know more than they do or that their original assessment was in error. It is easy to panic and sell at just the wrong time. Yet if the security were truly a bargain when it was purchased, the rational course of action would be to take advantage of this even better bargain and buy more.
3. Setting an investment goal of achieving a specific rate of return, say 15%, is of no good use. It's better to just follow a disciplined value approach in investing, because by doing so, good result will ensue:
An investor cannot decide to think harder or put in overtime in order to achieve a higher return. All an investor can do is follow a consistently disciplined and rigorous approach; over time the returns will come. Targeting investment returns leads investors to focus on upside potential rather than on downside risk.
4. Always buy with margin of safety, remember that value investing is about avoid losing money:
Value investing is a risk-averse approach; attention is paid as much to what can go wrong (risk) as to what can go right (return).
The primary goal of value investors is to avoid losing money. Three elements of a value-investment strategy make achievement of that goal possible. A bottom-up approach, searching for low-risk bargains one at a time through fundamental analysis, is the surest way I know to avoid losing money. An absolute performance orientation is consistent with loss avoidance; a relative-performance orientation is not. Finally, paying careful attention to risk—the probability and amount of loss due to permanent value impairments— will help investors avoid losing money.
5. Should you worry when you've applied the margin of safety calculation to buy a security and find its price plunges further? No.
If the security you are considering is truly a good investment, not a speculation, you would certainly want to own more at lower prices. If, prior to purchase, you realize that you are unwilling to average down, then you probably should not make the purchase in the first place.
6. That being said, when buying securities, you should always leave some room to average down:
In my view, investors should usually refrain from purchasing a "full position" (the maximum dollar commitment they intend to make) in a given security all at once. Those who fail to heed this advice may be compelled to watch a subsequent price decline helplessly, with no buying power in reserve. Buying a partial position leaves reserves that permit investors to "average down," lowering their average cost per share, if prices decline.
Evaluating your own willingness to average down can help you distinguish prospective investments from speculations.
A value investor may experience poor, even horrendous, performance compared with that of other investors or the market as a whole during prolonged periods of market overvaluation. Yet over the long run the value approach works so successfully that few, if any, advocates of the philosophy ever abandon it.
7. Identify the situations where stock prices tend to depart from underlying value for non-fundamental reasons:
There are numerous reasons, the forces of supply and demand do not necessarily correlate with value at any given time. Also, many buyers and sellers of securities are motivated by considerations other than underlying value and may be willing to buy or sell at very different prices than a value investor would. If a stock is part of a major market index, for example, there will be demand from index funds to buy it regardless of whether it is overpriced in relation to underlying value. Similarly, if a stock has recently risen on increasing volume, technical analysts might consider it attractive; by definition, underlying value would not be a part of their calculations. If a company has exhibited rapid recent growth, it may trade at a "growth" multiple, far higher than a value investor would pay. Conversely, a company that recently reported disappointing results might be dumped by investors who focused exclusively on earnings, depressing the price to a level considerably below underlying value. An investor unable to meet a margin call is in no position to hold out for full value; he or she is forced to sell at the prevailing market price.
The behavior of institutional investors, dictated by constraints on their behavior, can sometimes cause stock prices to depart from underlying value. Institutional selling of a lowpriced small-capitalization spinoff, for example, can cause a temporary supply-demand imbalance, resulting in a security becoming undervalued. If a company fails to declare an expected dividend, institutions restricted to owning only dividend-paying stocks may unload the shares. Bond funds allowed to own only investment-grade debt would dump their holdings of an issue immediately after it was downgraded below BBB by the rating agencies. Such phenomena as year-end tax selling and quarterly window dressing can also cause market inefficiencies, as value considerations are subordinated to other factors.
8. I have missed some good opportunities to make great fortune due to adherence to value investing and not following the herd and chasing the hot stocks, should I abandon value investing then?No.
True, conservatism may cause investors to refrain from making some investments that in hindsight would have been successful, but it will also prevent some sizable losses that would ensue from adopting less conservative business valuations.
the same view can be found in The Interpretation of Financial Statements
“The investor who buys securities only when the market price looks cheap on the basis of the company's statements, and sells them when they look high on this same basis, probably will not make spectacular profits. But, on the other hand, he will probably avoid equally spectacular and more frequent losses. He should have a better than average chance of obtaining satisfactory results. And this is the chief objective of intelligent investing."
9. To be really really conservative, should I make an investment only when I feel that I have learned all information about it? No, even if information is not 100% available to you (In fact, you can never learn 100% present information in any investment), you should consider the investment if it is truly a bargain with large margin of safety.
Most investors strive fruitlessly for certainty and precision, avoiding situations in which information is difficult to obtain. Yet high uncertainty is frequently accompanied by low prices. By the time the uncertainty is resolved, prices are likely to have risen. Investors frequently benefit from making investment decisions with less than perfect knowledge and are well rewarded for bearing the risk of uncertainty. The time other investors spend delving into the last unanswered detail may cost them the chance to buy in at prices so low that they offer a margin of safety despite the incomplete information.
10. Catalyst is a perfect way to close the value gap and realize your profit so that it can be turned into cash again:
Value investors are always on the lookout for catalysts. While buying assets at a discount from underlying value is the defining characteristic of value investing, the partial or total realization of underlying value through a catalyst is an important means of generating profits. Furthermore, the presence of a catalyst serves to reduce risk. If the gap between price and underlying value is likely to be closed quickly, the probability of losing money due to market fluctuations or adverse business developments is reduced. In the absence of a catalyst, however, underlying value could erode; conversely, the gap between price and value could widen with the vagaries of the market. Owning securities with catalysts for value realization is therefore an important way for investors to reduce the risk within their portfolios, augmenting the margin of safety achieved by investing at a discount from underlying value.
11. Maintain a good balance in portfolio liquidity. Do not be 100% invested in illiquid investments at any point in time. If you put money in illiquid investment, make sure the rewards are high enough to compensate your bearing of illiquid risks:
Since no investor is infallible and no investment is perfect, there is considerable merit in being able to change one's mind. If an investor purchases a liquid stock such as IBM because he thinks that a new product will be successful or because he expects the next quarter's results to be strong, he can change his mind by selling the stock at any time before the anticipated event, probably with minor financial consequences. An investor who buys a nontransferable limited partnership interest or stock in a nonpublic company, by contrast, is unable to change his mind at any price; he is effectively locked in. When investors do not demand compensation for bearing illiquidity, they almost always come to regret it.
Most of the time liquidity is not of great importance in managing a long-term-oriented investment portfolio. Few investors require a completely liquid portfolio that could be turned rapidly into cash. However, unexpected liquidity needs do occur. Because the opportunity cost of illiquidity is high, no investment portfolio should be completely illiquid either. Most portfolios should maintain a balance, opting for greater illiquidity when the market compensates investors well for bearing it.
This portfolio liquidity cycle serves two important purposes. First, as discussed in chapter 8, portfolio cash flow—the cash flowing into a portfolio—can reduce an investor's opportunity costs. Second, the periodic liquidation of parts of a portfolio has a cathartic effect. For the many investors who prefer to remain fully invested at all times, it is easy to become complacent, sinking or swimming with current holdings. "Dead wood" can accumulate and be neglected while losses build. By contrast, when the securities in a portfolio frequently turn into cash, the investor is constantly challenged to put that cash to work, seeking out the best values available.
