Why Jim Cramer Is Wrong About Doing Your Homework

When I worked on Wall Street, CNBC played on the TVs around the trading floor. Most of the traders were gone by 5:30 pm, but I was usually one of the last people on my team to leave. On an otherwise quiet trading floor, Jim Cramer’s show, Mad Money, was a jolt of energy. Cramer would blitz his audience with a dizzying blur of stock picks and sound effects. He doesn’t take himself too seriously (unlike the rest of Wall Street), and his show was pure entertainment.

The premise of Jim Cramer’s investment philosophy, which includes not only the Mad Money show but numerous books as well, is that ordinary investors can beat the market by shrewdly picking individual stocks. He doesn’t advocate day trading, but instead advocates medium-to-long term investing through individual stocks. He says that ordinary investors can make good money (or should I say, “Mad Money”), by picking good companies. Why hold every stock in an industry, he argues, when you can buy companies that are the “best of breed”.

Jim Cramer: Buy and Homework

Cramer quickly caveats that investors should not “buy and hold”, but “buy and homework.” He emphasizes to viewers that in order to pick stocks successfully, you need to do your homework.

Of course, you should do your homework when deciding to purchase a stock, but the homework should not stop once the buy order is filled. He advocates doing one hour of homework a week for every stock in your portfolio. You need to continually monitor events related to the company and how it might affect the stock’s future prospects.

For example, if the company decides to acquire a competitor or reports poor quarterly earnings, you need to re-evaluate whether the company is still worth keeping. Holding a stock should not be a passive “set it and forget it” process, but an active process, Cramer argues.

Seems easy enough, right?

Why Jim Cramer Is Wrong About Doing Your Homework

The problem with Jim Cramer’s approach is that a diversified portfolio needs at least 10 stocks, but probably closer to 20. You still don’t get the diversification of holding 500 stocks like you do with an S&P 500 index fund, or the 3,500 stocks you get with a total stock market index fund.

Cramer has a recurring segment on his show called Am I Diversified? Viewers call in and give Jim their top 5 stock holdings, and Cramer will tell them if they’re diversified. If they’re not diversified, he’ll tell them which stocks to buy and sell.

At a minimum, you’ll need 5-10 hours a week to tend to your portfolio. Here are three reasons why you shouldn’t bother doing your homework, and should forget trying to beat the market with individual stocks:

Do you have 5-10 hours to work on your portfolio?

I’m not sure where busy physicians, residents, or medical students will find the time to do their homework. Medical students definitely should be studying instead of researching investments. Spending those 5-10 hours on studying, becoming better doctors, or re-charging is a much better investment than tending to your stock portfolio.

Residents are already working way too many hours, and have no time to be managing their (tiny) portfolio of stocks.

Attending physicians probably have the time to do their homework if that’s how they choose to use their precious free time. But time is money, and I’d much rather make extra money by taking extra shifts than spend it trying to pick stocks. An emergency physician or anesthesiologist can make $200/hr by picking up extra shifts. You could potentially earn an extra $100,000 a year ($200/hr x 10hr/week x 50 weeks/year) with the time you spend doing your “homework”.

Or you could invest in a three-fund portfolio and have fun playing golf, sipping on a nice wine, or playing with your kids.

I’d rather be playing golf than doing “homework.”

You probably won’t be able to beat the market anyway

Do you think you’d be able to beat LeBron James in basketball practicing 5-10 hours a week? Professional investors spend thousands of hours and millions of dollars searching for the tiniest of edges.

Most of us got into medical school because we studied hard and outworked our fellow students. An hour a week per stock is not outworking your competitors. They have superior technology, better access to research, and more experience than any amateur investor.

Even the professionals repeatedly struggle to beat the market, largely because they are playing a game that is increasingly hard to win.

It will take more than effort to beat the market

You need the resources and access to beat the market. Research analysts at Apple do market checks where they look for changes in the supply chain that might affect their ability to produce a product on time. Analysts in restaurant stocks will do store checks to see if there is more or less foot traffic than the month prior, which might influence same-store sales growth, and in turn the stock price.

There is no way for the average investor to do this kind of homework. Sure, you could probably find this information on the Internet, but a lot of this information will be from expensive, proprietary research reports that the average investor will never read.

Plus, you never know whether the person on the other side of the trade has inside information.

Conclusion

Jim Cramer is selling a hope that all of us have, that we can make mad money with just a little bit of effort. I suspect physician investors are more susceptible to this belief than even average investors. We’ve been the best at what we do our entire lives, and if we just do enough homework just like we did in college and medical school, we can achieve the same success in investing as we have in medicine. Unfortunately, you can’t out-homework Wall Street.

  1. My sister-in-law is a mutual fund manager, and we sometimes talk about investing. People that work on and around wall street do it as a full-time job—often MORE than full-time—job. So, as you say, it doesn’t compute that Joe investor can expect to compete doing it as a part-time hobby. Better to Vanguard and Fidelity and forget it.

  2. I was one of the physicians that tried this strategy. I quickly fell behind in my homework and it showed. You have to admit Jim Cramer is entertaining though. Probably for the same reason people watch NASCAR.

  3. I definitely do not have 5- 10 hours for home work. I barely have enough time for this blog! The money shows always drive me a little batty. They are like all other consumer commercials, trying to get me to do something I really don’t want to.

  4. There was definitely a time where I’d spend time doing my homework and trying to outsmart every other investor. I learned the hard way that it’s not going to happen and my time is better spent elsewhere. I’d rather be playing golf too!

  5. I used to watch Jim religiously. I remember one of his red hot picks. Buy, buy, buy. Sears. Need I say more…..it got to the point watching the show, where I would do the opposite. He said buy, I would sell. That strategy had better returns than listening to his picks. THEN… I found nirvana. The 3-fund portfolio and I have never been more at ease. Vanguard for life.

  6. I am a big Cramer fan but the average person just does not have the time (or the ability) to analyze stocks. The best bet is to just stick to low cost index funds and spend the time you would have spent studying the stocks with your family or working. You will have better returns overall.

  7. I humbly disagree. I am from an accounting background. With the knowledge of being able to read the financial statements (and 10Q/annual) I am able to eliminate some of his picks. Refer to rich dad poor dad by robert kiyosaki on how to read financials for the average Joe. You still do your own homework after his picks and before (during and after) you buy. I beat the averages the last 5 years running, I underperformed my first 2 years due to owning too many speculation junk stocks. But the moral of the story is, you can do it; no one will take better care of your money than you. Good luck

  8. My name is Tom Peacock from USA, I want to say thank you to Dr Emu for the good thing he has done for me, Though am not sure if this is the best forum to show my joy and happiness for what he has done for me but i can’t hide my happiness and my joy so i have to share it with people, my marriage got crashed about two years ago and i tried all i could within my power but to no avail. I saw a post and testimonial about the good things Dr Emu has been doing so I decided to give it a try. though he is always a busy man but when he responded back to my email, he gave me 48 hours for my marriage to be restored really just like he said my marriage was restored since then I am happy and i am living happily i am so grateful to Dr Emu you can always email him here: {emutemple@gmail.com} or WhatsApp: {+2347012841542}

  9. My husband and I are another successful clients of Cyber Genie Intercontinental among many. I read countless positive reviews about how they have been using their cyber expertise to help people achieve their happiness back by recovering their scammed or lost Bitcoin and assets from fraudulent and posers of Cryptocurrencies trading companies. After reading many of the wonderful services they render, I had to contact them because my husband was seriously defrauded by some Chinese bitcoin miners, it all ended in goodwill as we were able to recover what we thought we had lost to scammers. Contact them on [ Cybergenie  AT  cyberservices  DOT  com  ] WHATSAPP [ +1 ] 252-512-0391 ] and help yourself from depression.

  10. HOW I FINALLY RECOVERED MY LOST CRYPTO: I lost all my crypto to a fake investment scam to someone I met online. I started searching for help legally to recover my funds, and I came across a lot of Testimonies about HACKER STEVE. I contacted him, providing the necessary information and it took him and his team of experts about 36 hours to locate and help recover my stolen funds. I am so relieved and the best part was, the scammer was located and arrested by local authorities in his region. I hope this helps as many out there who are victims. I strongly recommend Steve professional services for assistance with swift and efficient recovery (Crypto, Credit card, Forex, NFT, etc) on Gmail: Hackersteve911@gmail.com | https://hackersteve.great-site.net/
