4月21日，投顾张鹏在今日市场分析中指出，上周A股市场走出9连阳，但成交量却跌破万亿，呈现出缩量上涨且高位横盘的态势。这种走势引发了市场对未来走势的担忧，许多投资者不确定下周大盘是否会下跌，以及是否应该加仓或减仓。

Zhang Peng pointed out that there is a very strange thing about the recent trend of A-shares: the trend of the index is often red in the last few minutes of the end of the session. For example, last Tuesday, the market fluctuated sharply, and the last half hour was red; The index itself fell last Wednesday, and was finally pulled by the Shanghai Composite 50 to close in the red; Last Friday, the index fluctuated at a low level throughout the day, and the end of the market forcibly pulled red, and finally formed a false positive line. This phenomenon shows that the intraday index has actually been in a weak position, although the index was finally forcibly red, it seems that the market has a money-making effect, but in fact, many investors are losing money, and many institutions are wait-and-see. This is also the reason why the market index has been rising, but the trading volume of the two markets has shrunk sharply.

Zhang Peng emphasized that the basic law of the stock market is that if you want to have a big rise, it must be accompanied by the amplification of trading volume. Because as the stock price rises, the price will go higher, and the stock funds must be amplified, otherwise the upward momentum will be insufficient. At present, the market continues to pull up the index, but every day is barely a small white line, and the closing increase is very small, indicating that there is no volume contribution, and the index is difficult to get out of the big market. Under the influence of the "mysterious force", the index forcibly closed in the red, which made shareholders lose their vigilance, but as stockholders, we must know that only the amount can be amplified in order to get out of the big market, and the current market should not chase up, nor should it be heavy.

Looking at the heavyweight stocks represented by the Shanghai Stock Exchange 50 Index, they are also facing the problem of continuous rise but substantial shrinkage. The mysterious force is pulling bank stocks, but bank stocks have shrunk significantly from their highs after rising for two consecutive days. Zhang Peng pointed out that the high level can be reduced in the short term, but the volume must be increased in the later stage, otherwise the banking sector is very likely to have a pullback. Once the weighted sectors such as the banking sector begin to pull back, it will be difficult for the market to continue to maintain a red market.

Therefore, Zhang Peng reminded investors that the current market must not be full, investors should set aside spare positions, advance and retreat, and beware of the killing after the index rises immeasurably.
