Chapter 6: measurement approach Flashcards
what is the measurement approach?
approach under which accountants undertake a responsibility ot incorporate current values into the FS proper, providing that this can be done with reasonable reliability, thereby recognizing an increased obligation to assist investors to predict firm perf/value.
What are the 2 versions of current value accounting
Fair value (exit price) and value in use (PV of future cash receipts or payments)
Why are accountants moving towards measurement approach?
1) Securities markets may not be fully efficient
2) to extent that investor not fully rational and markets not fully efficient, a measurement perspective may improve deicison making and market efficiency.
3) low R2 ***
Ohlson’s clean surplus theory
- low proportion of share price variability explained by net income.
- theoretical framework supportive of a measurement approach.
Behavioural finance.
characteristics that question investor rationality and market efficiency:
1) limited attention: no time, inclination, ability to process all info
2) conservative: excess weight in prior beliefs
3) overconfidence: overestimate precision of self collected info
4) representativeness: too much weight to evidence consistent with impressions drawn.
5) self-attribution bias: good outcome = ability, bad outcome = unfortunate realization of nature.
6) motivated reasoning: skeptical of info inconsistent with preferences.
–> do security prices reflect all publicly avail. info?
Prospect theory
1) Separate evaluation of gains and losses (narrow framing: isolate problems in too isolated a manner)
2) weighting of probabilities: overconfidence (event probabilities under-weighted) , representativeness (event prob overweighted)
3) Disposition effect: Hold on to losers and sell winners
4) Earnings management to avoid small losses (small gap just before 0)
Does CAPM have ability to explain stock returns
little ability to explain stock returns. (higher beta should be higher return but empirical results are weak)
What variabls other than beta better explain stock returns
book to market ratio and firm size.
what are positive feedback investors? What effect do they have on the markets
positive feedback investors buy when stock price begins to rise. LEads to excessive market volatility
Bubble
share prices rise far above fundamental values (extreme case of market volatility)
Why do bubbles form?
biased self-attribution and momentum. positive feedback trading and herd behaviour reinforced by optimistic media prediction of market experts
Was 2008 a bubble?
Maybe not. The risky investment strategies of financial institutions caused the bubble. This may not have been public information.
Anomalies
market inefficiency. share prices may not fully react to F/S right away or may not extract all info content from F/s
Post announcement drift
GN leads to abnormal return drift upward for some time. investors underestimate the implications of current earnings on future earnings.
Post announcement drift arbitrage
buy GN shares and short other companies shares whose returns were perfectly correlated with efficient market price changes of the GN shares. PAD is less if there is higher institutional ownership b/c they are better able to capitalize on the arbitrage opportunity.
