does a stock go back up like PCA when they say public offering

Yes, it is possible for a stock to go back up after a public offering, also known as an IPO. The performance of a stock in the aftermarket, which is the period after its IPO, can vary based on various factors such as market conditions, investor sentiment, and the company's financial performance.

In some cases, the stock price may fluctuate in the aftermarket due to the increased supply of shares available for trading. However, if the company has strong fundamentals, such as solid financials and a clear path to growth, the stock may be able to regain its initial value or even increase in price.

It is important to note that the performance of IPOs can be highly volatile, and investors should conduct thorough research and consider their risk tolerance before investing in any stock, including PCA.
