Good Rule For Stocks Investing


Hi Welcome to my new post
This post is on Stock marketing
Here i am mentioning

Good Rule For Stocks Investing

Warren Buffett’s fortune is enough to stupefy anyone. Starting from scratch, he has amassed a fortune of billions and billions of dollars. And the most amazing part of that feat is not even that – it is the fact that he has achieved so much wealth in his lifetime purely by investing in the stocks and bonds of companies.

As he has mentioned a number of times, he credits much of the framework with which he invests to Benjamin Graham, his mentor and teacher from whom he learned how to invest. Thus, it should be of immense interest to anyone who wants to invest wisely, to hear what Graham has to say on the subject of the maximum price one should pay for buying a stock. After all, this is a perennial question that comes to the mind of investors – What is the right price to pay?

For the purchase of a stock to be successful, every investor relies on future earnings of the company and not its past earnings. But at the same time, Graham was of the firm opinion that when evaluating a stock and its future earnings, one can be conservative only by basing this opinion on company’s actual performance over a period of time in the past. Thus, in most cases, the investment (and not speculative) value of stock can be arrived at by taking into consideration the company’s average earnings over a period of five to ten years.

The company’s profit in the most recent year may be taken as the base for arriving at the value in some cases, but only if it meets the following criteria –

(1) general business conditions in that year were not exceptionally good

(2) the company has shown an upward trend of earnings for some years past

(3) the investor’s study of the industry gives him confidence in its continued growth

And only in the extremely rare and exceptional case should one rely on the assumption of a company achieving higher earnings in the future while calculating the price one pays. Higher future earnings should be taken into consideration only if it is a 100% sure thing, which is very rarely the case.

The above was a discussion of Graham’s suggestion of which earnings should one take as the base when valuing a company by using a P/E ratio. Now for the second part – what would be the right multiple one should give those earnings to arrive at the price one should pay for the stock?

A conservative investor may rightfully give a very attractive company a higher multiple. This may be a company whose latest earnings are above its past average, which has extremely promising future prospects, or has an inherently stable earnings power. However, at the very heart of Graham’s argument was his opinion that there must always, in every case, be some upper limit of this multiple that is assigned to the stock in order to stay conservative in one’s valuation. He suggested that about 20 times average earnings is the highest price that can be paid buying a stock from an investment perspective. While this is the maximum one should pay for a company considered to have very good prospects, about 12 or 12.5 times average earnings would be suitable for the typical company with average prospects. This is because investment, as opposed to speculation, necessarily requires demonstrated value, which can be verified only by way of average earning power in the past. A P/E multiple of 20 in effect means an earnings yield of 5% (1 divided by 20).

It would indeed be very hard to conservatively justify average earnings of less than 5% of the market price of a stock without betting your money on an increase in earnings of the company in the future. Thus, according to Graham, a price to earnings ratio of higher than 20 times average earnings cannot by any means provide the margin of safety that an investor should have. It might be accepted by an investor in expectation that future earnings will be larger than in the past. But such a basis of valuation would then have to be termed “speculative”. That is because speculation derives its basis and justification from potential developments that differ from past performance.

By the above thumb rule of not paying more than 20 times average earnings, Graham did not imply that it would be mistake to do so. He suggested instead that such a price would be speculative. Further, it should also be noted that such a purchase can easily turn out to be highly profitable, but in that case it will have proved to be a merely fortunate speculation. And very few people are consistently fortunate in their speculation.

Hence people who habitually purchase stocks at more than about 20 times their average earnings “are likely to lose considerable money in the long run” according to Graham. This is all the more likely because if such a mechanical check were not enforced, investors have the tendency to time and again give in to the temptation and lure of bull markets, which always find some or the other deceptively pleasing argument to justify paying extravagant prices for stocks.

Foriegn Bridegroom??? - Be care full









Hi friends Once again welcome


All of us seeing that searching for bridegroom in foreign(states) is common thing. and parents are looking for a bridegroom from Foreign especially from USA.
But we need to be careful when choosing a bridegroom from States. Because now a days all we are seeing in TV's about foreign bridegroom frauds . We are sending our daughter with other guy to unknown place which is 1000's Km from our place. So we need to be careful.

In this case we should collect more information about him as much as possible.
Those details are
Passport :
This is must and should . We need to have a look at this.There will be his address. We need to confirm his specified address in the passport . Because we are seeing fake passports also. So we need to confirm his passport address.

Social Security Number :
This is a security number given by foreign government to every one. We should collect this and verify this by our relatives in that country.If we pass this number to our relatives ,they can check that number and details whether those details are real or fake.

Job details:
We should collect his job details like company name,address,Id given by that company, Post in that company,How long he has been working in that company. We can have a look at that company if we have those details.

His family background :
We should collect all his family details , and we should ask about them in their city or village . like how is that family will be, what are their character.


If we take above precautions when selecting foreign bride groom our daughters life will be very happy

Optical fiber communication advantages

Hi,
Today i cam e with a little bit old communication technology.

Now a days Wireless communication became popular .Because there is one important advantage i.e no need of wires.

But before this technology We have one communication technology which is easier to perform and cheap to establish. That is none other than OPTICAL COMMUNICATION.
In This communication main element is Glass(optics) which is known as fiber .This is very thin as much as our hair and very chep because glass is made up of silica ( sand).






In the present time, we have ultra low loss fibers(0.001 dB/Km) so that the optical signals can be transmitted through the fiber over a very long distances with low loss. Thus the optical fibers are dielectric waveguides which transmit the optical signals or data through them with very low attenuation and very low dispersion . If we soliton laser pulses one can transmit the signals almost without any loss or dispersion. Thus one can achieve very high band width or high data rate using fiber optic cables. Now a days, we have dispersion free and dispersion compensation fibers.


Let us see the advantages of optical fiber communication over conventional communication system.

1. ENORMOUS BANDWIDTHS:
The information carrying capacity of a transmission system is directly proportional to the carrier frequency of the transmitted signals. The optical carrier frequency is in the range of 10^14 Hz while the radio frequency is about 10^6Hz and microwave frequency is about 10^10Hz. Thus the optical fibers have enormous transmission bandwidths and high data rate. Using wavelength division multiplexing operation, the data rate or information carrying capacity of optical fibers is enhanced to many orders of magnitude.

2.LOW TRANSMISSION LOSS:
Due to the usage of ultra low loss fibers and the erbium doped silica fibers as optical amplifiers, one can achieve almost loss less transmission. Hence for long distance communication fibers of 0.002 dB/Km are used. Thus the repeater spacing is more than 100Km.

3.IMMUNITY TO CROSS TALK :
Since optical fibers are dielectric wave guides, they are free from any electromagnetic interface (EMI) and radio frequency interface(RFI). Since optical interference among different fibers is not possible, cross talk is negligible even many fibers are cabled together.

4.ELECTRICAL ISOLATION:
Optical fibers are made from silica which is an electrical insulator. Therefore they do not pick up any electromagnetic wave or any high current lightening. It is also suitable in explosive environment .

5.SMALL SIZE AND WEIGHT:

The size of the fiber ranges from 10um to 50um which is very very small. the space occupied by the fiber cable is negligibly small compared to conventional electrical cables. Optical fibers are light in weight. These advantages make them to use in aircrafts and satellites more effectively.

6.SIGNAL SECURITY:
The transmitted signal through the fiber does not radiate. Unlike in copper cables, a transmitted signal cannot be drawn from a fiber without tampering it. Thus , optical fiber communication provides 100% signal security.

7.RUGGEDNESS AND FLEXIBILITY:

The fiber cable can be easily bend or twisted without damaging it. Further the fiber cables are superior than the copper cables in terms of handling, insulation, storage, transportation, maintenance, strength and durability .

8.LOW COST AND AVAILABILITY:
Since the fibers are made of silica which is abundance. Hence, there is no shortage of material and optical fibers offer the potential for low cost communication.

9.RELIABILITY:
The optical fibers are made from silicon glass which does not undergo any chemical reaction or corrosion. Its quality is not affected by external radiation. Further due to its negligible attenuation and dispersion,optical fiber communication has high reliability.


All the above factors also tend to reduce the expenditure on its maintenance.

This is all about optical fiber advantages.

Next time i will come back with another post.

Why 800MHz?





















Hi friends.Welcome to my new post . This time i came with a topic on Cellular mobiles


Now a days Mobile phone is common thing for every one.At least there is one mobile for every 50 peoples in our country. So we should learn about mobile communication and its frequencies.

Why people are going for these Cellular Mobile Phones, rather than using conventional mobile telephone systems ?
Because conventional mobiles have below limitations
  1. Limited Service Capability
  2. Poor service Performance
  3. Inefficient spectrum Utilization
Here Spectrum utilization plays important role in today's scenario ,as number of users increasing rapidly from day to day

So let us talk about Spectrum using in Cellular Communication
In Cellulars we are using 800MHz. there is a story behind this.Today i will tell you about that

We have FCC , Which is known to be as Federal Communication Commission.This FCC decides everything for cellulars.It Made a decision for using 800MHz in Cellular communication
The FCC's decision to choose 800MHz was made because of severe spectrum limitations at lower frequency bands.
FM broadcasting services operate in the vicinity of 100MHz.
The Telivision broadcasting service starts at 41MHz and extends up to 960MHz.

Air-to-ground systems use 118 to 136MHz;military aircraft use 225 to 400MHz.The maritime mobile service is located in the vicinity of 160MHz.Also fixed-station services are allocated portions of the 30 to 100-MHz band. Therefore, it was hard for FCC to allocate a spectrum in the lower portions of the 30- to 400-MHz band since the spectrum in the lower portions of the 30- to 400-MHz band since the services of this band had become so crowded. On the other hand, mobile radio transmission cannot be applied at 10GHz or above because severe propagation path loss, multipath fading, and rain activity make the medium improper for mobile communications.

Fortunately, 800 MHz was originally assigned to educational TV channels. Cable TV service became a big Factor in the mid-70s and shared the load of providing TV channels. This situation opened up the 800-MHz band to some extent, and the FCC allocated a 40-MHz system at 800 MHz to mobile radio cellular systems.
Although 800 MHz is not the ideal transmission medium for mobile radio, it has been demonistrated that cellular mobile radio system that does not go beyond this frequency band can be deployes. Needless to say, the medium of trasmitting an 800-MHz signal, although it is workable, is already very difficult.


Recovery of Bio mass

hi friends Here i came with new topic .This topic is on Biomass
Today our environment is getting polluted by human activities. Today in the world for every 1000 people there are 10-20 machines which uses petrol or diesel like cars, bikes,generators, and so on.... By using this we are polluting the environment. One remedy for this id use of Bio-gas products like biomass.these products can't pollute the environment. So we should encourage everyone using these products. so today i would like to share recovery of biomass in the future and these are also renewable energies .

In developed countries like USA ,Canada,Russia it is difficult for an agriculturist to decide how to best use his land.If the object is to use the land in the best ecological way possible, a slow down cycling of the biomass will be recommended in the first place. The agriculturist should decide to do silviculture. For example, wood can be used to build houses. After the house has been deconstructed, the quality of the wood is still good enough to serve as material for wardrobes or rail tracks and then to make boxes or art works. Only after such a long cycle should the wood be combusted. If the object is to use the land in the best economic way possible, the financial aid of governmental institutions will be particularly considered. Depending on the institutional programs, it may well be most profi table to cultivate energy plants to produce biodiesel or ethanol. But maybe it will be most effi cient even to have the agricultural area lying idle, as the government may have assigned higher financial benefits to it as if it was used to cultivate, e.g., food plants.


If the agricultural area is to be used to maximize the yield of renewable energy, a combination of different technologies will be most efficient, e.g., wind turbines installed to generate electricity, with photovoltaic cells underneath and the cultivation of grass or energy - affording plants at an even lower cultivation of two different energy - affording plants in sequence is most profi table.
If liquid manure is available, the biomass is recommended to be fermented in a biogas plant; otherwise it is to be combusted. If the yield of fuel is to be maximized, it is recommended that starch - based plants rather than fat - containing plants should be cultivated to minimize the loss
of energy during transformation processes.Biomass in general will achieve much greater importance as a primary carrier for energy supply in the near future. This will lead to signifi cant changes in the personal habits of people and in the agricultural cultivation methods applied today. Humankind is almost forced to face those changes given the fact that resources of fossil energy carriers are running short. It may be possible in the remote future to meet the energy demand by using biomass only.

It is highly critical that the developed markets should adjust to the required changes as quickly as possible. The emerging markets, in contrast, should not imitate the developed markets, but must take different approaches immediately to recover and secure the supply of energy.

This is all about recovering of Biomass for future purposes
