Now that the index is coming down again, fear sets in and everyone is waiting till the market recovers again, to buy. Only successful investors are buying when there is fear in the market. Which is hard to do on reality, but, that is why tempremant plays a key role in investing success.
Again, when the index crosses 6000 and even 7000, and believe me they will, all the frustrated investors or gamblers will complain that they could not get in when the index dropped to 5000.
Investing is long term. Make use of these market fluctuations
