We recently compiled a list of the 8 Stocks on Jim Cramer’s Radar. In this article, we are going to take a look at where AST SpaceMobile, Inc. (NASDAQ:ASTS) stands against the other stocks.

Jim Cramer, the host of Mad Money, recently shared some investment guidelines based on his 40 years of experience. As we previously discussed in our article, Jim Cramer Talked About These 8 Stocks, Cramer emphasized that both bulls and bears can profit, but greed leads to losses, advising investors to take profits and avoid being overly greedy. His second rule is that paying taxes is acceptable. Finally, Cramer stressed the importance of not making large, all-at-once buys or sales, recommending gradual adjustments to positions instead.

In addition to these guidelines, Cramer’s next rule was to recognize the importance of distinguishing between damaged stocks and damaged companies. He explained that buying stocks from companies that are fundamentally flawed is a mistake with no chance of recovery, but stocks of companies that are simply experiencing temporary issues may present a buying opportunity. This distinction is critical because, as Cramer pointed out, there’s no “money-back guarantee” when buying into a company with long-term problems.

Investors should focus on finding stocks that are down for reasons that aren’t related to poor company fundamentals. Cramer then moved on to his next rule, which is to always do the relevant homework.

“If you want to build a portfolio of individual stocks, that’s a big if since there’s nothing wrong with getting all of your equity exposure from a cheap index fund that mirrors the S&P 500, well, you gotta be rigorous about it. Which brings me to my next rule: Do the homework.”

Cramer said that doing the homework means more than just picking stocks based on a gut feeling; it involves actively researching companies by listening to earnings calls, reading research reports, and staying on top of the news. Cramer noted that some investors dismiss this kind of work, seeing it as unnecessary or outdated in today’s fast-paced world. However, he was clear in his belief that failing to do proper research before buying stocks is foolish and can lead to poor investment choices.

Cramer further emphasized that doing homework today is easier than ever. With so much information available on the internet, there’s no excuse for not gathering as much data as possible. For those who don’t have the time or inclination to dive deep into individual stocks, Cramer suggested that index funds are a great alternative. Another crucial rule that Cramer continually stresses is the importance of diversification.

“The next rule is another essential that I harp on constantly: Diversify, diversify, and diversify. Always be diversified, that controls risk, and managing risk is really the holy grail of this business. What’s the biggest risk out there? It’s called sector risk.”

Sector risk refers to the potential for a specific sector of the economy to lag, which can result in negative impacts on investments within that sector. Cramer explained that sector risk is one of the most significant dangers to an investment portfolio, and diversification is the only way to protect against it.

He frequently says that “diversification is the only free lunch in this business” because it’s the one investment principle that benefits everyone. As per Cramer, by mixing different sectors in a portfolio, at least five according to him, investors can prevent themselves from suffering catastrophic losses if one particular sector takes a hit.

“Here’s the bottom line: Whether you’re an amateur or professional, you always need to do your homework and keep your portfolio diversified. This is the kind of routine maintenance that protects you from monster losses down the line. Remember, if you can keep your losses to a minimum and let your gains run, you almost always come out ahead. But don’t try to rationalize those losses because stocks don’t always come back to even or anywhere near that.”

Our Methodology

For this article, we compiled a list of 8 stocks that were discussed by Jim Cramer during the episodes of Mad Money. We listed the stocks in ascending order of their hedge fund sentiment as of the third quarter, which was taken from Insider Monkey’s database of 900 hedge funds.

Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 275% since May 2014, beating its benchmark by 150 percentage points (see more details here).

AST SpaceMobile, Inc. (NASDAQ:ASTS)

Number of Hedge Fund Holders: 18

Cramer emphasized that AST SpaceMobile, Inc. (NASDAQ:ASTS) is a spec stock and mentioned he doesn’t want it to make up a significant portion of an investment portfolio.

“There’s a whole bunch of stocks that all are very speculative and if people wanna speculate, I am not against it. I just don’t want it to be a large part of your portfolio. This company’s losing money hand over fist. Doesn’t mean the stock can’t go down, but it does mean that it’s not worth anything other than a spec.”

AST (NASDAQ:ASTS) is a company focused on developing a space-based cellular broadband network to provide global mobile connectivity, particularly in areas lacking terrestrial coverage. Despite its ambitious goals, it reported a loss of $171.95 million for the third quarter, which was a significant increase from the $20.91 million loss in the same period the previous year. On a per-share basis, the loss reached $1.10.

Operating expenses also climbed from $58.9 million last year to $66.6 million, driven by higher research and development costs as well as increased expenses for engineering services. However, as Cramer noted in a previous episode, “It’s a space stock, and space is loved right now”, the stock is up over 380% year-to-date. Additionally, the company saw a notable increase in its stock value on December 9 following the announcement of a 10-year commercial agreement with Vodafone, one of Europe’s largest telecommunications companies.

This deal is expected to further expand AST’s (NASDAQ:ASTS) reach, particularly in Africa, where Vodafone has a significant presence. Vodafone has ordered its first BlueBird gateway from the company, allowing users outside cellular coverage to connect smartphones to satellites in low Earth orbit. The gateway will route data into Vodafone’s network, enabling broadband and internet access.

Overall ASTS ranks 6th on our list of stocks on Jim Cramer’s radar. While we acknowledge the potential of ASTS as an investment, our conviction lies in the belief that AI stocks hold greater promise for delivering higher returns and doing so within a shorter timeframe.
