Some analysts have argued that the recent market rally does not reflect the true value of the stock prices and that there is very little correlation between the general health of the economy and the stock market. The former Fed chairman, Alan Greenspan, appearing on CNBC’s Squawk Box, stated that there is no “irrational exuberance” and if anything, the stocks are undervalued. It’s important to point out that Greenspan failed to foresee the last bubble. Writing for the Daily Beast, Daniel Gross argued that when celebrities start showing interest in stocks, it is time to leave the market. Gross was referring to Mila Kunis’ appearance on CNBC, which according to the author is a sign that “stupid money is in play”. He then compared the trend to Joseph Kennedy’s experiences as a master speculator. Kennedy realised that when shoeshine boys started dispensing stock tips in the 20’s, it was time to get out of the bull market.
