Psychology And Bad Market Timing.


wealthymatters.comEvery stock investor whether a technical or fundamental or value investor ultimately needs to take a call on whether he/she wishes to buy or sell at the price Mr. Market sets at any given time.How much an investment ultimately nets a person depends on the timing of the buy and sell decision and the actual price at which the transaction takes place,despite all the theories of averaging out and time in the market and reversion to the mean.

The following is a checklist of mental mistakes that may affect a person’s decision to buy or sell and cost a him/her dearly. The checklist is from Whitney Tilson’s presentation ‘How to Avoid – and Profit From – Manias,Bubbles and Investor Irrationality”

•Failing to Buy

–Status quo bias

–Regret aversion

–Choice paralysis

–Information overload

–Hope that stock will go down further (extrapolating recent past into the future; greed) or return to previous cheaper price (anchoring)

–Regret at not buying earlier (if stock has risen)

Tilson On Common Mental Mistakes


wealthymatters.comWealthymatters reader , Andy Cheung , in response to yesterday’s post : Some Assumptions To Check Before Investing has sent a  link  to an excellent article by Whitney Tilson on common mental mistakes humans persistently make while investing . I think the article should be essential reading for all people who hope to make it good by investing.I didn’t want to just leave the link hidden among the comments,so I have posted a copy of the list of mistakes people make here.The link below will take you to the complete explanation of these mistakes.

1)Overconfidence

2)Projecting the immediate past into the distant future

3)Herd-like behavior (social proof), driven by a desire to be part of the crowd or an assumption that the crowd is omniscient

4)Misunderstanding randomness; seeing patterns that don’t exist

5)Commitment and consistency bias

6)Fear of change, resulting in a strong bias for the status quo Read more of this post

Some Assumptions To Check Before Investing


wealthymatters.comThe human brain is fascinating in the way it can use a rough form of inductive logic to help us make sense of our very complex world.But the human brain is not infalliable.Mental heuristics in the form of common sense,educated guesses,rules of thumb,intuitive judgments,etc.can help us find a good enough solution fast, when an exhaustive analysis is impractical.But at the same time such heuristics can lead us to over-generalize and make mistakes.Here is a checklist of some common traps to avoid falling into while investing:

  • Correlating GDP growth and market performance. High GDP growth rates don’t always translate into stockmarket outperformance. This may be due to three reasons—(a) unlisted companies may contribute to a large part of GDP growth; (b) while the listed companies’ net profit may grow, dilution of capital through periodic issuances will adversely affect earnings per share (EPS) and return-on-equity (RoE), thereby, impacting stock prices; and (c) the nature of stockmarkets, which serve as leading indicators, resulting in prices surging ahead well ahead of the actual GDP growth and, then, plateauing out for a long period once the growth actually materialises.

Some Financial Thumb – Rules


wealthymatters.com

Financial thumb-rules are rough guides for making sensible financial decisions .However they have their  infirmities and so need to be used in the right context.Following are a few basic financial thumb-rules:

  1. Pay yourself first rule: From any money you make, put away atleast 10% first before you pay any bills or debts or do anything else with the money i.e. make your investments the first obligation on your money.The general idea is that this money will start working for you by earning interest , gaining in capital value or giving you rents etc. and in time you will need to work less and less as your money starts working for you.
  2. The emergency fund rule: Build a corpus equal to 3-6 months worth of expenses of your household.Life is uncertain and you never know when somebody might meet with an accident , fall sick , suffer losses in business , lose a job or suffer loses due to fires or natural calamities ,war, civil strife etc.The money is to take care of immediate expenses,provide a cushion to fall back on till you find your feet again and if necessary provide a small stake to start over again.The money needs to be kept in a safe place where there is no chance of loss of capital and where it can be withdrawn immediately and without hassles.
  3. 100 minus your age rule:This is a thumb-rule to determine how much of your paper assets should be in equities.The general idea is that as you grow older and wealthier you want less volatility and less risk of capital loss.Volatility might complicate withdrawls from the corpus in retirement and lost capital might not be so easily made up for later in life, after retirement.
  4. The 10,5,3 rule : This rule states that you can on an average expect returns of 10% on equities,5% on bonds and 3% on liquid cash and cash-equivalent accounts in the long run.It’s important to remember this rule before reaching for that extra half percent that might lead to capital loss.

An Investing Principles Checklist


wealthymatters.com

This is an investing principles checklist from ‘Poor Charlie’s Almanack’.I think it bears reading at frequent intervals just to ensure we aren’t doing something incredibly stupid or failing to do something basic that could better our investment records.

Risk – All investment evaluations should begin by measuring risk, especially reputational
  • Incorporate an appropriate margin of safety
  • Avoid dealing with people of questionable character
  • Insist upon proper compensation for risk assumed
  • Always beware of inflation and interest rate exposures
  • Avoid big mistakes; shun permanent capital loss

Independence – “Only in fairy tales are emperors told they are naked”

  • Objectivity and rationality require independence of thought
  • Remember that just because other people agree or disagree with you doesn’t make you right or wrong – the only thing that matters is the correctness of your analysis and judgment
  • Mimicking the herd invites regression to the mean (merely average performance)

Preparation – “The only way to win is to work, work, work, work, and hope to have a few insights”

  • Develop into a lifelong self-learner through voracious reading; cultivate curiosity and strive to become a little wiser every day
  • More important than the will to win is the will to prepare
  • Develop fluency in mental models from the major academic disciplines
  • If you want to get smart, the question you have to keep asking is “why, why, why?” Read more of this post
