The current stock market levels are synonymous with the old adage— many investors burn their fingers by investing when the markets are at an all time high. The S&P BSE Sensex has gained about 18 per cent in the first half of the year and is expected to go up a lot higher. However, the noise around the index levels being at an all time high is purely based on absolute figures. Let us understand this with an example—just the way Rs 10,000 today will not have the same purchasing power ten years hence (it did not have the same purchasing power ten years ago), the constant mention to indices hitting all-time highs is an incorrect expression of gauging the real worth of the markets.
