Jim Cramer refutes five bearish market concerns following Wednesday's market rebound.

• On Wednesday, CNBC's Jim Cramer advised investors not to fear the market, as he believed many were overly anxious.
• He requested that the professional bears appearing remember that it was not the day after Pearl Harbor, and that it was simply business as usual with no need to pretend the sky was falling.

On Wednesday, CNBC's Jim Cramer stated that investors should not be concerned in this market, as he listed five bearish "scares" that are typical of the market's natural rhythm and should not significantly impact Wall Street.

He requested that the professional bears appearing remember that it was not the day after Pearl Harbor, and that it was simply business as usual with no need to pretend the sky was falling.

1. Cramer stated that investors are concerned about a potential commercial real estate collapse and its impact on regional banks. Although there are some buildings with little value, he pointed out that a prominent investment trust is performing well and major banks have largely written down their commercial real estate assets. However, he added that this bear thesis may become irrelevant as companies bring more workers back into offices.
2. Wall Street is concerned that the Federal Reserve's next move may not occur soon enough to aid the market, according to Cramer. However, he maintained that the current period, which lies between a rate increase and a rate reduction, presents the ideal opportunity to purchase.
3. Despite anticipating a challenging period before earnings, shareholders have not experienced it yet, as Cramer noted, and even companies with lackluster reports have seen their stocks surge.
4. Although investors are hesitant to purchase when the market is controlled by Big Tech, Cramer advised seizing this opportunity to buy low in preparation for a broader market.
5. The tech giant's rapid rise is causing some market unease, but Cramer believes the gains are well-deserved and the stock is a keeper.

Cramer stated that scaring people is easy, and being a short-seller can also be profitable. When you're a short-seller, you won't be criticized for being incorrect; instead, you'll be invited to speak again when the market declines or is down because you have something to contribute.
