What Does UNCH Mean in Stock Prices?

If you check a stock price and see the abbreviation UNCH next to the stock symbol, this means the price is unchanged. UNCH can signify one of two things. These letters will appear if the security was traded and went through some price ups and downs, but settled at the price in effect at the end of the previous trading period. UNCH also could mean that the stock hadn't traded at all since the prior period.

Lack of Trades

Although a UNCH designation because of zero trades isn't surprising, it might or might not indicate a problem. A UNCH price because of no trades can be a curious situation, and you should research the security further.

UNCH With Trades

When a stock was traded and earns UNCH status, it typically means that the security was volatile in that period, with its price fluctuating up and down during the trading day. Although a stock price finishing UNCH is a neutral result, you might want to research why its price fluctuated during the trading period.


A listing of UNCH might or might not be significant. It could simply mean that investors ignored the stock during the trading period. However, a UNCH status also could mean that events, reports or press releases during the day led to equal increases and decreases because of real or perceived changes in operations and financial success or failure. UNCH means that the market as a whole found little significance in the company's stock or situation.


When you own a stock that finishes a trading day as UNCH, you haven't lost or made any profits. If the stock has been ignored by the market, you could ask why. The UNCH status, if there were multiple trades, could simply signify a coincidental result at the closing bell. Take some comfort in considering that although a stock that's UNCH didn't reach any strong highs, it also didn't suffer any damaging lows.

UNCH Not Rare

Heavily traded stocks can still have their prices unchanged in any given day. For example, The Wall Street Journal's Market Watch website recently reported results of 25 stocks' after-hours trading activity. Of the 25 securities, eight were UNCH. Three of the UNCH stocks had more than one million shares traded, with the highest volume at more than 10.5 million shares changing hands. Strong trading volume does not preclude the possibility of a UNCH status.
