Who would think of buying or selling a private business because of someone's guess on the stock market? The availability of a quotation for your business interest (stock) should always be an asset to be utilized if desired. If it gets silly enough in either direction, you take advantage of it. Its availability should never be turned into a livability whereby its periodic aberrations in turn formulate your judgements.
