Why is the stock price in CRSP preceded by a minus sign?

Sometimes you see negative stock prices in CRSP. This means that there was no closing price available for that period. Instead, the bid/ask average was used. To distinguish the bid/ask averages from actual closing prices, CRSP puts a leading dash in front of the price when the bid/ask average was used. If neither price nor bid/ask average is available, Price or Bid/Ask Average is set to zero.

    • Have you checked for stock splits etc? You also have to check if CRSP gives you the closing price or the bid ask average (that’s when the – is used). Please use our question form for questions like this.
