I think "risk in time" is the key. Some stocks listed today, perhaps not so many gold stocks, will be de-listed within the next few years, some simply because they run out of money as no one is prepared to back them. Others of course will disappear off the board as they are taken over.
I think we are all very much more risk averse today. One can no longer take the risk of punting on the "penny dreadfuls" in the hope they may strike gold or oil or gas.
I'm just glad I did very thorough research before buying CRK which also fits the criteria.
I think we'll do very well indeed with these stocks but it may take a while. I'll wait.
