MCAD, RSI, EMA,.. (eng)

Saturday, August 5th, 2006

U prošlom unosu sam spomenuo neke kratice, vjerujem da većina zna što one znače, a oni koji ne znaju su, vjerujem, iskoristili linkove s lijeve strane te doznali. Ipak, ukratko ću pokušati objasniti njihovo značenje, kako ne bi trebali prekidati čitanje i tražiti njihovo objašnjenje.

Relative Strength Index (RSI) Izuzetno popularan pokazatelj ustanovljen od strane Wallesa Wildera Jr. te objavljen u njegovoj knjizi 1978 godine. RSI se prikazuje na skali podijeljenoj između 0 i 100, s tri podjele, na vrijednost "30", zatim središnju liniju koja označava vrijednost "50" te vrijednost "70". Kad RSI vrijednost padne ispod brojke 30, smatra se da je dionica podcijenjena (oversold), a ako je vrijednost iznad 70, smatra se da je precijenjena (overbought). Promjena vrijednosti RSI indexa, u skladu s ostalim pokazateljima, može značiti promjenu kretanja cijene (vrijednosti) dionice (trend reversal).

Exponential Moving Average (EMA) Prikazuje prosjek kretanja cijene određene dionice u određenom periodu s tim da svojim izračunom daje veću ''težinu'' nedavnim podacima s ciljem da ukloni nagle pokrete indikatora, odnosno da nam da fluidniji prikaz kretanja cijene.

MACD (Moving Average Convergence/Divergence) Indikator ustanovljen od strane Geralda Appela, izračunava se oduzimanjem 26-razdoblja eksponencijalnog prosječnog kretanja cijene određene dionice od njenog 12-razdoblja eksponencijalnog prosječnog kretanja cijene. Prikazujući te vrijednosti, MACD nam može prikazati momentum kretanja cijene, odnosno prikazati u kojem bi se smjeru vrijednost dionice (najvjerojatnije) mogla kretati u budućem periodu.

*Iako se trudim pisati na hrvatskom, mnogi pojmovi još nisu prevedeni na hrvatski, ili su njihovi eng. nazivi općeprihvaćeni te ću navesti i eng. inačicu tj. originalnu verziju.

Relative Strength Index (RSI) A popular oscillator developed by Welles Wilder, Jr. and described in his self-published 1978 book "New Concepts in Technical Trading Systems". RSI is plotted on a vertical scale from 0 to 100. Values above 70 are considered overbought and values below 30, oversold. When prices are over 70 or below 30 and diverge from price action, a warning is given of a possible trend reversal. See ChartSchool article on Relative Strength Index.

Moving Average (MA) An average of data for a certain number of time periods. It "moves" because for each calculation, we use the latest x number of time periods' data. By definition, a moving average lags the market. An exponentially smoothed moving average (EMA) gives greater weight to the more recent data, in an attempt to reduce the lag.

MACD (Moving Average Convergence/Divergence) An indicator developed by Gerald Appel that is calculated by subtracting the 26-period exponential moving average of a given security from its 12-period exponential moving average. By comparing moving averages, MACD displays trend following characteristics, and by plotting the difference of the moving averages as an oscillator, MACD displays momentum characteristics.

Trader Psychology [eng/long]

Thursday, June 29th, 2006
Discipline

lose money

One of the key factors mentioned by almost every good trader is discipline. Discipline, as you might imagine, takes a variety of forms. For beginning traders, one of the toughest challenges is to keep trades small. Believe it or not, more than a few top traders don’t allow any one position to account for more than 1% of their total portfolio. Linda Bradford Raschke, one of the traders featured in The New Market Wizards, attributes much of her success to managing risk in this way. As a result, her average trade, at the time the interview, had a profit of only $450. At the same time, her average loss was only $200. Keeping her position small didn’t impede her profit though. By remaining disciplined, she earned over $500,000 trading that year.

Limiting Your Losses

Another aspect of trading that involves discipline is limiting your losses. Here, there isn’t a magic formula that works for everyone. Instead, you have to determine your own threshold for pain. Whatever you decide, stick to it. One of the biggest mistakes people make is to take a position with the intention that it be a short-term trade. Then, when the position goes against them, they make a seamless and unprofitable transition from trader to long-term investor. More than a few people have gone broke waiting for the trend to reverse so they could get out at break-even. If you are going to trade, you have to be willing to accept losses–and keep them limited!

Another mistake novice traders make is getting out of profitable positions too quickly. if the position is going well, it isn’t healthy to worry about giving it all back. If that’s a concern, you might want to liquidate part of the position or use options to lock in your profit. Then, let the rest of it ride. Mark Ritchie, one of the founders of CRT, an extraordinarily profitable Chicago-based trading company, once kept a trade on for 4 years because it kept working for him. Not every trader has that kind of patience. And not every trader makes as much money as Mark Ritchie.

It isn’t uncommon for people to view trading as a fast-paced, exciting endeavor. Fast-paced? Absolutely. Exciting? Now that’s a matter of opinion.

The Importance of Remaining Even-Tempered

More than a few traders interviewed in The New Market Wizards emphasize the importance of remaining unemotional and even-tempered. To these people, trading is a game of strategy that has nothing to do with emotion. Emotion, for these traders, would only cloud their judgment.

In the book, Charles Faulkner, a Neuro-Linguistic Programming trainer talks about one trader who was extremely emotional. Although Faulker was able to show him how to be less emotional and more detached, it became quickly apparent didn’t enjoy being emotionally unattached. He found it boring. Unfortunately, emotion involvement in trading comes at a high price. Before too long, that trader went broke. The morale of the story is simple: If you insist on being emotionally attached to your trading, be prepared to be physically detached from your money.

Acceptance and Responsibility

One of the most interesting interviews in the book was with Robert Krausz, a member of the British Hypnotist Examiners Council who specializes in working with traders. According to Krausz, one of the biggest mistakes traders can make is to agonize over mistakes. To beat yourself up for something you wish you hadn’t done is truly counterproductive in the long run. Accept what happens, learn from it and move on.

For the same reason, it’s absolutely crucial to take responsibility for your trades and your mistakes. If you listen to someone else’s advice, remember that you, and you alone, are responsible if you act on the advice.

Another Way to View Losses

Perhaps the most striking example of emotional distance in trading mentioned in Schwager’s book was attributed to Peter Steidlmayer who reacts to positions that go against thinking to himself, “Hmmm, look at that.” If only we could all be that calm!

Of all the emotions we could possibly experience, fear and greed are possibly the two most damaging.

Fear

Of all the emotions that can negatively impact your trading, fear may be the worst. According to many of the traders interviewed in The New Market Wizards, trading with scared money is an absolute recipe for disaster. If you live with the constant fear that the position will go against you, you are committing a cardinal sin of trading. Before long, fear will paralyze your every move. Trading opportunities will be lost and losses will mount. To help deal with your fear, keep in mind what fear is:

Confidence

The flip side of fear is confidence. This is a quality that all great traders have in abundance. Great traders don’t worry about their positions or dwell on short-term losses because they know they will win over the long term. They don’t just think they’ll win. And they don’t just believe they’ll win. They KNOW they’ll win. As Linda Bradford Raschke put it, “It never bothered me to lose, because I always knew that I would make it right back.” That’s what it takes.

To Talk or Not to Talk

For many traders, sharing opinions and taking a particular stance only magnifies the stress. As a result, they begin to fear being wrong as much as they fear losing money. Although it may be one of the hardest lessons to learn, the ability to change your opinion without changing your opinion of yourself is an especially valuable skill to acquire. If that’s too hard to do, the alternative may prove much easier: Don’t talk about your trades.

Greed

Greed is a particularly ugly word in trading because it is the root cause of more than a few problems. It’s greed that often leads traders to take on positions that are too large or too risky. It’s greed that causes people to watch once profitable positions get wiped out because they never locked in profits and instead watched the market take it all back.

Part of the remedy for greed is to have, and stick to, a trading plan. If you faithfully set and adjust stop points, you can automate your trading to take the emotion out of the game. For example, let’s say you are long the 50 calls in a stock that rises more rapidly than you ever expected. With the stock at $77, the dilemma is fairly obvious. If you sell the calls, you lock in the profit but you eliminate any additional upside potential. Rather than sell the calls, you might buy an equal number of 75 puts. The $25 profit per call that you just locked in will more than offset the cost of the puts. At the same time, you’ve left yourself open to additional upside profit.

Gradual Entry and Exit

Another strategy successful traders use is to gradually get in and out of positions. In other words, rather than putting on a large trade all at once, buy a few contracts and see how the position behaves. When it’s time to get out, you can use the same strategy. Psychologically, the problem people have implementing this strategy is that it takes away the “right” and “wrong” of the decision making process. It’s impossible to be completely right or completely wrong using this strategy because, by definition, some of the trades will be put on at a better price than others.

Awareness & Instincts

For floor traders especially, instincts often play a crucial role in trading. To truly appreciate this, just close your eyes and imagine making trades in a fast market with dozens if not hundreds of people screaming around you. In this environment, it becomes absolutely essential to maintain a high level of awareness about everything going on around you. Then, to have the confidence to pull the trigger when necessary, you have to trust your instincts. It’s absolutely amazing to see how some floor traders, even in a busy market, know exactly who is making what trades. For these traders, expanded awareness is often a necessary prerequisite to fully developing and trusting their instincts.

The same is true for off-the-floor traders as well. Watching how markets behave and developing a feel for the price fluctuations is truly time well spent. Unfortunately, in this era of technology, people have become so removed from their natural instincts that many are no longer in touch with their intuition. This is unfortunate because intuition functions as a wonderful inner guidance system for those who know how to use it.

One trader interviewed by Jack Schwager in The New Market Wizards relies so heavily on his intuition that he didn’t want his name in the book for fear his clients would be uncomfortable with his strategy and move their money elsewhere. Speaking anonymously, he described in detail how he establishes a rhythm and “gets in sync” with the markets. In this way, he has learned to distinguish between what he “wants to happen” and what he “knows will happen.” In his opinion, the intuition knows what will happen. With this knowing, the ideal trade is effortless. If it doesn’t feel right, he doesn’t do it.

When he doesn’t feel in sync with the markets, this trader will virtual trade until he feels back in rhythm. But even here, he keeps his ego and emotion out of it. His definition of out of sync is completely quantifiable. Being wrong three times in a row is out of sync. Three mistakes and it’s back to the virtual trading. Now there’s a strategy almost everyone can benefit from.

Hedge fondovi

Tuesday, November 15th, 2005
  
Hedge fondove (eng. hedge funds) bi mogli nazvati ''divljim'' fondovima, oni u pravilu nisu registrirani i ne podliježu zakonskim regulama koje moraju ispunjavati registrirani investicijski fondovi.
 
U početku je osnovna ideja hedge fondova bila osigurati povrat na ulaganje (eng. hedge = zaštita), dok su danas hedge fondovi u principu usredočeni na rizik kako bi ostvarili što veći prinos. Iako u pravilu ostvaruju veće prinose od drugih (investicijskih, mirovinskih,..) fondova, baš zato što su usredočeni na rizik nisu pogodni individalnim invesitorima, čak i u slučaju kad je početni ulog poprilično nizak, cca. 25.000 USD.  
 
Sad se neki pitaju ''kako to smiju biti neregistrirani?''. Nitko ne može zabraniti, npr. određenoj skupini članova koji prate investicijske forume ili blogove da zajednički udruže znanje i vrijeme, te iz zajedničkog računa investiraju novac. SEC pokušava regulirati poslovanje hedge fondova, ali i dalje ne uspjeva, bar ne u značajnijoj mjeri. Prednost takvih fondova nad investicijskim fondovima je ta što hedge fondovi smiju trgovati na način koji nije dopušten investicijskim fondovima, npr. smiju shortati, ulagati u bilo koje dionice na bilo kojem tržištu, opcije i futurese, te poslove izvan tržišta vrijednosnica, baš kao i samostalni investitor. Namijenjeni su u pravilu velikim korporacijama i imućnijim investitorima, najviše zbog zakonskih regulativa (SEC) koji nisu blagonakloni prema (riskantnim) hedge fondovima, npr. poneki hedge fondovi imaju minimalni ulog od milijun pa čak do 25 milijuna dolara, a neki su uz sve to i jednostavno zatvoreni za nove klijente (npr. Cramer Berkowitz). Također, SEC je zabranio oglašavanje hedge fondova, odnosno, ako su neregistrirani, nema se tko oglašavati.
 
U Americi djeluje oko 9000 hedge fondova, a po procjenam taj broj se svake godine poveća za 10%. Službene statistike ne postoje jer u US zakonu nema definicije hedge fonda, a i velik broj istih se registrira off-shore.  
 
Mutual fondovi, za razliku od Hedge, su registrirani i nadgledani od strane SEC-a, a jedna od regulativa kojoj podliježu mutual fondovi je ta da im nije dopušteno svojim fond managerima plaćati proviziju od zarade (kod Hedge ona ponekad iznosi i 50% od zarade, npr. Simons i Cohen), što mogi vide kao razlog relativne neučinkovitosti managera u Mutual fondovima.
 
Ipak, mutual fondovi raspolažu s oko 8 tisuca milijardi dolara ($7.818 trillion), za razliku od Hadge fondova koji raspolažu s oko 1100 milijardi dolara, po procjenama iz 2004. godine. Od negativnih strana treba spomenuti pojavu "divljih" hedge fond managera, tj. osoba koje nisu sposobne obavljati taj posao, ali zbog nedostatka SEC regulative, i slabe informiranosti, klijenti znaju pogriješiti pri izboru svog Hegde managera.
 
Procjenjuje se da u cijelom svijetu ima preko 9 tisuca Hedge fondova te da se taj broj svake godine poveća za 10%. Službene statistike ne postoje jer u US zakonu nema definicije hedge fonda, a i velik broj ih se registrira off-shore (Kajmansko otočje, Bermuda, Britanski Djevičanski otoci,..). Najpoznatij među hedge fondovima su Soros Fund Management, Clinton group, Bridgewater, Pequot,..
Hedge fondovi su organizirani kao "partnerstvo", gdje je glavni manager također i glavni savjetnik (investitor), a financijeri ("klijenti") partneri. Ujedno su i netransparentni, što znači da ne moraju objavljivati gdje i kako ulažu novac svojih klijenata. Velik broj hedge fondova je registriran offshore, kako bi izbjegli plaćanje poreza.
 
Špekulira se čak da su Hegde fondovi odgovorni za nagli porast cijene nafte kojima smo svjedoci posljednjih par godina, a razlog tome je, navodno, ulaganje najjačih Hedge fondova u futurese (o futuresima baš možete pročitati na OptionMasterovom blogu) na naftu. Kako investicijskim fondovima nije dozvoljeno shortati, oni su "osuđeni" na gubitak u bear marketu, dok hegde fondovi zarađuju i kad padaju cijene, sto shortanjem, sto pisanjem i/li kupovinom opcija.
 
Nisu pogodni široj javnosti i zbog mnogo većeg rizika od gubitka sredstava, veliki investitori su toga u potpunosti svjesni i spremni su riskirati u zamjenu za prihod veći no što bi ostvarili kod klasičnih investicijskih fondova, dok mali investitor najčešće to sebi ne može priuštiti. Prosječna naknada je 1-2% od uloženih sredstava, te 20-50% od dobiti, što je drastično više nego kod klasičnih investicijski fondova. Neki od poznatijih hedge fond managera su George Soros i Jim Cramer (Mad Money), koji je 2000. godine kad je DOW pao -6%, a S&P500 -11%, na "svom" portfelju zaradio +36%. Prošle godine je najveći prihod imao hedge fond kojem je manager Edward Lampert iz ESL Investments Inc., 1.2 milijarde dolara, kako je objavio PR Newswire.

Hedge fondovi postoje već nekoliko desetljeća, ali o njima se počelo pisati tek nakon što je 1998. godine jedan hedge fond (LTCM) izgubio 4.6 milijarde dolara (dotad im je prosječan godišni prihod bio +40%), te time ugrozio čak cjelokupan bankarski sistem zbog velikih iznosa kojima banke kreditiraju hedge fondove. Ako vas zanima nešto više o tome, možete pročitati knjigu ''When Genius Failed'' autora Rogera Lowensteina.

 
 James Simons Alpha cover
 
James Harris (Jim) Simons, Ph.D. is a cryptanalyst, mathematical physicist, academic, investment advisor, billionaire and philanthropist. In 1982, Simons founded Renaissance Technologies Corporation, a private investment firm based in New York with over $12 billion under management; Simons is still at the helm, as president, of what is now one of the world's most successful hedge funds.[1] According to Institutional Investor magazine, Simons earned an estimated $1.5 billion in 2005[2] (the largest compensation among hedge fund managers that year [1]) and $670 million in 2004. Simons' most influential research involved the discovery and application of certain geometric measurements, and resulted in the Chern-Simons form (aka Chern-Simons invariants, or Chern-Simons theory). In 1974, his theory was published in Characteristic Forms and Geometric Invariants, co-authored with the differential geometer Shiing-Shen Chern. The theory has wide use in theoretical physics, particularly string theory. With an estimated current net worth of around $4 billion, he is ranked by Forbes as the 64-richest person in America.

Jesse Livermore (1877-1940)

Wednesday, November 9th, 2005

 

Jesse Livermore

 

Iako je preminuo prije ravno 65 godina i danas se o njemu govori kao jednom od najcjenjenijih tradera svih vremena. Poznat i pod nadimcima poput Boy Plunger, The Great Bear, The Wall Street Wonder i Cotton King, Livermore je čak četiri puta za vrijeme svog traderskog staža izgubio, tri puta i ponovo stekao, multi-milijunske vrijednosti, ako bi tadašnji milijun pretvorili u današnje odnose, govorili bi o milijardama dolara. On je čovjek kojeg su držali odgovornim za veliki slom burze 1929. godine, a svoje «prste» je imao u svim većim krizama od 1917 do 1940. godine kad je i preminuo, odnosno kad je izvršio samoubojstvo. Iza njega su osim nebrojenih citata ostale dvije izuzetno cijenjene i danas rado čitane, odnosno knjige koje su obvezno štivo svakog tradera: "Reminiscences of a Stock Operator" i "How to Trade Stocks". O njemu bi se moglo ispisati par stranica teksta, ali za to će već trebati ili uposliti Google ili Amazon i kupiti njegove knjige. Izdvojiti ću samo neke od njegovih citata:

"Fear your losses and let your profits run"
"It was never my thinking that made me money but my sitting tight"
"Markets are never wrong, opinions are"

Većinu svog bogatsva je stekao shortanjem za vrijeme sloma burze  (prilikom market crash-a 1929.god je zaradio preko 100 milijuna usd), a filozofija ili princip trgovanja mu je bilo dokupljivanje pozicije koja ide u željenom smjeru i brza prodaja ako krene u neželjenom smjeru (cutting losses quickly).  

Ironično, nije se baš uvijek držao svojih principa što ga je na kraju i koštalo gubitka cijelog bogatstva, poslušao je savjet prijatelja i dokupljivao poziciju koja je bila u gubitku.

 
Kraj world greatest stock tradera

In the Squibb building at 745 Fifth Avenue, he entered in the Sherry-Netherland Hotel on November 28, 1940, at 4:30 in the afternoon. By 5:33 he walked through the swinging doors and slipped through the closed door of a dim, dark, cloakroom. He sat on a stool at the end of the cloakroom. He withdrew a .32-caliber Colt automatic pistol (he bought the gun in 1928 while he was living in Evermore). He placed the barrel of the gun behind his right ear and pulled the trigger. He died instantly.[10] Livermore was 63 years old.

The police revealed that there was a suicide note of eight small handwritten pages in Livermore's personal notebook. It was reported in the November 30th of the New York Tribune[11].

Although untouchable trusts and cash assets at his death totalled over $5 million, he had failed to regain his trading confidence by his death. A lifelong history of clinical depression had finally become the dominant factor in his final years.

Today, Livermore is regarded by many professional traders to be the greatest trader in history.

   

Zanimljivo da je on bio samo jedan od poznatih businessman-a koji su život skončali na tragičan način, npr.:

1. Predsjednik najveće US željezare, Charles Schwab, je umro u bijedi.

2. Predsjednik najveće naftne kompanije, Edward Hopson je psihički nastradao.

3. Predsjednik newyorkške burze (NYSE), Richard Whitney je pušten iz zatvora da umre u svom domu, također bez novčića.

4. Najpoznatiji trader pšenicom, Arthur Cooger, umro na nepoznatom mjestu, kao prosjak.

5. Predsjednik internacionalne banke, Leon Fraser, izvršio samoubojstvo.

6. Ivar Krueger, predsjednik International Match Corp., također izvršio samoubojstvo, iako neki tvrde da je ubijen.
