Stock Certificate In two names
The DOW is just an index, which is simply a group of stocks meeting the criteria for inclusion. In the case of the DOW, it's the 30 US stocks with the largest market capitalization, but other indices include many lesser stocks (such as the S&P500 or the Russell 2000). The fact that Holobeam is no longer a constituent of the DOW30 probably shouldn't be taken in and of itself as a signal to sell the stock. As far as I can tell, HOOB stock is still trading on the Nasdaq exchange. However, it is extremely ill-liquid, which means that there are very few people willing to buy or sell it. Whether or not this would work to your advantage is almost entirely down to luck - it depends whether there is a keen buyer out there at the time you try to sell.
