“Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than mathematical expectations, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits—a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.” – John Maynard Keynes
Bull and Bear
Bull and bear are the most commonly used in the context of market trends. Bull charges ahead ignoring anyone in his path, this mentality in the stock market drives stock prices high and bullies others into higher investments. Thus the term bull market is an optimistic one, which reflects an improving economy with an underlying belief that stocks will climb higher. A bull charges ahead, thrusting horns upwards, looking upwards. Bullish trend thus implies where stock prices are increasing and money is flowing into stocks. A Bullish market sees high investor confidence. It is typically an improved market performance over a period of months or years and can be in the context of the market as a whole or just a particular stock. Bull market signals to strengthen the economy.
A Bear, on the other hand, tears things down with his claws. Similarly, a bear market reflects shredding hopes and confidence with bullish investors selling or short selling everything, thus bringing down prices across the board. This trend reflects pessimism toward market performance. Bears, swipe down their prey, tearing it as in this case, and market confidence to shreds filled with pessimism and negative sentiment. Typically the threshold for a bear market is a more than 20% downturn by major indices like S&P 500 or Dow Jones Industrial average over two months.
