Why does low trading volume means?

Low trading volume refers to a situation in which the trading activity in a particular security or market is not as high as expected. It can have several implications:1. Weak Longs: Low trading volume in an uptrend may suggest that the long-term uptrend remains intact, but it also indicates that the current move is being driven by weak longs who are taking profit rather than by strong buyers.2. High Volume Pullbacks: On the other hand, high volume pullbacks occur when there is a significant spike in trading volume in the opposite direction of the trend. This could be a sign that the smart money is starting to look for the exits and the trend is getting ready to reverse. 3. Liquidity Premium: Low trading volume can also result in a "liquidity premium," where less-liquid stocks are priced lower than more liquid stocks. This is because investors demand a higher return to compensate for the risk of not being able to easily sell the low-volume stock at a later date.In summary, low trading volume can indicate weak longs taking profit, an impending trend reversal, or a lack of investor interest in a particular security. It's important to consider other factors and indicators to confirm these sentiments and make informed trading decisions.
