Because the fed has spoken, and the fed did its best to do exactly what most people want except for the bears. Hence the rally with the dow gaining 113 points, s p gaining 0. 84 , nasdaq advancing 0. 74 . You may have heard a ton of verbiage today about what the fed or didnt do. It kept in the word gradual when it talked about future rate hikes, took out the word only, forecasting two more hikes making three for the year which is not surprising. In short, the fed basically did exactly what they said they would do, and without a surprise, the market soared. Hallelujah. So why does the market rally on a nonnews event . If an tornado entity like the fed simply does what people expect, why the heck is that greeted as positive by both the stock market and in some ways more important the bond market where Interest Rates went down, down hard . Nah, thats the wrong way to look at it, people. What happened today is the fed didnt surprise anyone. There was a fear that the fed could say it needs to raise rates with alacrity because of inflation picking up. That would have slammed the bond market too. The fed could have said it sees the economy accelerating. Inflation is kind of under control, so well raise three more times this year, not just two. A Statement Like that would have moved the bank stocks up. They were amojs todays weakest performers. But it could have sent the industrials down on fears the fed would throw us into recession. Maybe it was too triggerhappy. Or the fed could have raised rates by 50 basis points, shocking everyone, telling you it sees President Donald Trump triggering growth with inflation, so they have to rein him in and act as a counter to the white house. That would have been totally toxic. And a strong sign that the fed perceives itself as a bunch of grownups lining up against all the tax reform, meaning budget busting initiatives that trump favors. Hey, listen, those were all possibilities. They were outside possibilities but they were possibilities. And when they didnt happen, buyers were relieved, and they came in strong, took everything. Yep, the fed tried to figure out what would be the least impactful, most informed action it could make with the least surprising statement, and they delivered it, unleashing a lot of pent up cash. Now, lets talk about reality for a second. In the last few weeks, weve interviewed a slew of executives on this show about how their businesses are doing. We spoke to one of the largest aggregate companies called stone, martin marietta, deeply involved with the construction of big projects and roads and their order books are bursting. Coo ward nye says its about as great environment as hes seen. We spoke to the ceo of u. S. Concrete. He says business is quite simply terrific. You pour concrete when you choose to build Something Big that puts people to work. Infrastructure, headquarters, tall buildings. I was shocked at how positive things are. We discussed the state of the state, meaning the United States with greg hayes, the ceo of one of the large of the conglomerates in the world, united technologies. He indicated that orders were way up for elevators, heating, ventdlation and air conditioning equipment. What does that say . It says nonresidential construction is going gangbusters. In fact, the biggest gaining factor, United Technology needs more workers. Remember, nonresidential construction means big business. We spoke to one of the largest makers of equipment for restaurants, wellability, and its ceo told us that business is very good. Okay, not out of control great but very good. Then we talked to the ceo of prolodgis, among the largest distribution Warehouse Companies in the country with a fabulous read on everything commerce, especially ecommerce. He couldnt have described a more robust environment. In fact, its about the best demand level hes ever seen and its getting better. The big issue will be building out enough space to meet his customers requirements. Then last night we spoke to the ceo of nucor, the largest Steel Company in america. He was incredibly bullish of how business is shaping up for 2017. Meanwhile, of course, behind the scenes, im constantly talking to ceos, as many as i can in everything from banking to technology to basic industrial. Theyre not on air, but theyve all echoed the comments from the ceos i just mentioned. Now, understand thats the reality. Its incredibly good as weve tried to present a full panoply of what goes on in actual business in this country. But remember last night i told you that perception can sometimes trump reality, and i like that double trump entendre. If the fed said anything that indicated inflation was running hot or that the government, meaning trump, might ignite too much growth so it has to be kept on a leash to avoid labor shortages, then all those positive ceo interviews, they would have been rendered moot. What would happen . Sellers would have come into the market. Why . They would say that whatever commentary you heard on mad money, that was all in the past, and now the future is gloomier, and stocks trade on the future. Traders would dump these stocks because of a belief that their executives dont understand that the fed is now the enemy, not their friend. And others would say, look out. Janet yellen and the fed are declaring war against trump because theyre concerned hes all about busting the budget and giving huge tax breaks for the rich that we cant afford. We got none of that. Instead, what i regard as a predictable statement by a group of predictable people who want employment to keep improving predictably. Thats predictable. Plus i should add its a nice buck 28 rally in oil after hitting our 47 down side target. Many investors can take action and buy the shares of Companies Like the ones i mentioned because their projections are liable to come true now that we know the feds isnt getting in the way. At the same toorks because the fed told us that inflation is not really a factor, then Interest Rates came down because there are always people who take their cue from what the fed said, and the fed basically indicated bonds are a good buy. Why do i say that . Because in an environment with moderate growth, bonds are worth buying at these level. So the bond market equivalent stocks got bought too, the ones with the higher yield. Too good to be true . No. It simply reflects that fed chief janet yellen is thoughtful, rational, and doing the right thing for all Financial Instruments and far more important, for actual businesses like the ones i mentioned. She wants more people to work. I think this rationality when coupled with the current logjam in washington over the repeal and replace of Affordable Care means we can afford to wait for lower corporate taxes and repatriation. Its okay theyre auto out in t now. Ple buyers field emboldened with a rotation into the stocks of the Interest Rate sensitives and then the most beaten down groups, mainly the minerals and the oils. Proving once again that you shouldnt panic tiny a rotation. You simply need to let it run its course and then start nibbling. Heres the bottom line. A couple of days a year we are totally hostage to the fed. It used to be all the time. Now its just a couple days. Today the fed set us free, set us free to invest in reality, banish the perception that it wants to derail stocks, bonds, and the economy itself. And thats how you get one of the biggest rallies of 2017. Alex in california, alex. Caller booyah, jim. How are you . I am good there, chief. How about you . Caller im fine, thank you. Im calling you from lakewood, california. I watch your program in the morning. You guys are funny. You know, we do our best. Whats going on . Caller i wanted to ask you this question regarding the rate hike. How its going to affect the banking sector, domestic banks and international banks, and what do you think of Credit Suisse in long term . I like Credit Suisse. I prefer actually i actually like barclays more for european banks. Heres what i have to tell but banks. Initially they go down because some people are looking for three rate hikes and then they go back up. So just like i told you to buy the oils when it hit the 47 down side target, a couple days will buy the banks. Theyll be right again. As a matter of fact, for action alerts, my Charitable Trust, were telling club members that maybe its time to put some money in the banks if they go down again. Lets go to phil in high home statement of new jersey, phil. Caller booyah, jim. How are you . I am good. How about you . Caller good. Im looking forward to spring, looking forward to our fighting phils. I cant wait for them to play. It will be something positive. Hopefully we have something to look forward to this year. My question to you is about black stone. About two years ago i purchased black stone around 33. Since then the stock has done nothing but go down. Back in february, it reached 31, and then it pulled back again and recently came back up again. Some analysts said action is going to double. I agree with you about the fighting phils. Its fun to have them back. Ill tell you this, i think you got a great stock there. I think the stock market is allowing some companies to come public, and that will make black stone do better. I think that the stock is a buy here. Lets go to leanne in maryland, leanne. Caller hi, jim. Thanks for taking my question. Sure. Caller i have stock in Spectra Energy and it has merged with, ebrege.

Presuming this Obamacare Repeal and replace bill doesnt make it through congress in whatever current form that its in, something that now seems increasingly likely, what parts of the Health Care Cohort could be work picking at here . I always like to fall back on long term themes and unfortunately some of the best themes out there are chronic diseases that keep afflicting more and more people. Take diabetes. Currently more than 29 million americans are diabetic and another 86 million are prediabetic, meaning theyre seriously overweight and at risk of getting type 2 diabetes. Given the rise of the stay at home economy where its easier than ever to just sit on your couch, order everything you need off the web, watch netflix, play video games, i think these numbers are only going to get worse, not better. I bet those mall worker numbers you know those people Walking Around the mall, i bet you theyre down big. Now that mad money has entered lucky year 13, i want to remind you about one of the things i think we do best, which is to highlight ideas, show you various ways to play them, and then teach you how to evaluate these stocks for yourself so that you can do your own homework and get comfortable with them. This shows a starting point. When it comes to diabetes, ive got three favorites, and they have all different pluses and minuses. Theres dexcom, dxcm, insulate, and eli lilly, lly, a traditional company. Dexcom is a specialist medical Device Company that makes continuous Glucose Monitoring systems. Basically they have a little patch sensor that you put on your skin. It reads your blood sugar levels and then transmits the information to a wireless receiver that tells you everything you need to know. The receiver can be as simple as your cell phone. Thats a huge step from the old ways of doing things, which involves pricking your finger with a needle perhaps a dozen times a day if youve got type 1 diabetes. Now, ive been recommending dexcom pretty consistently for the last six years. Over that time, the stock has given us a fabulous nearly 500 gain although over the past couple years, candidly its performance has been more choppy. Thats a polite word, as the medical device stocks have rapidly swung into and out of favor with the wall street fashion show. Still dexcoms growing rapidly and earlier this year we learned that medicare would start paying for their latest device. Its the only continuous glucose monitor on the market thats getting medicare reimbursement, which is a very big deal. The stock exploded higher on the news in january, but i wouldnt be surprised if its got more room to run. The reason . First of all, even before that great medicare news, dexcom already had very Strong Revenue growth. This stock is measured by revenue growth. Its up 31 in the latest quarter. While that was a bit of a deceleration from its growth rate the year before, we have to expect the growth will reaccelerate as the company starts to get medicare and medicaid business. While that decision wasnt a surprise, the governments timing sure was. Coming a year to 18 months before anyone else expected it, including the company. What else . Dexcoms collaborating with google life sciences. Thats part of the big alphabet complex to come up with smaller devices and make better use of the data that they already collect. Next year dexcom is planning to launch the next iteration of the Monitoring System. This is the g6. So far the accuracy numbers weve seen from this thing are incredibly impressive. Nevertheless, every stock has its potential down sides. Thats important. We got to focus on those too. Dexcom is no exception. Remember, i want to teach you how to evaluate stocks here, which means you need to know both the good and the bad. In dexcoms case, there are ongoing competitive concerns surrounding a major opponent. What a competitor, medtronic, which came out with an art official pancreas, basically a Monitoring System like dexcoms combined with an automated insulin pump. I think getting medicare reimburse. More than cancels out the damage, but its something you need to be aware of. The other problem is dexcom is not yet profitable although thats because the Company Keeps spentdsing aggressively to invest newer products. Id be more worried here if dexcom didnt have such a clean balance sheet. One last worry. Obviously if the gop does manage to pass this current obamacare replacement bill that will cut medicaid spending, thats very bad news for dexcom and really almost the entire Health Care Sector although it sure isnt acting that way. The sector has been strong. Im not trying to be political here. Its not worth it. Just the fact that fewer people with insurance means fewer customers for dexcom. How about insulate. If dexcom gives diabetics a better way to measure their blood sugar. Insule terks gives people a better way to control it. A light weight wearable insulin pump that helps diabetics deal with their disease in a much more efficient and painless way than traditional ins list injections. Plus if youre wearing an automated insulin pump, you cant forget to take your insulin, which is something that can be a serious problem for people with diabetes. Combine the pod with dexcoms Monitoring System, as many patients do, and youve got something very close to medtronics socalled artificial pancreas except you have to finetune it yourself. Remember, i told you medtronics is good. Insulet makes a superior product compared to its competition. Theyre install base is growing by leaps and bounds, up 25 since last year. The company has got a number of partnerships outside of diabetes with businesses that want to use their Drug Delivery technology. Amgen, which by the way has an important Analyst Meeting friday, they use it for chemotherapy. On the other hand, the pod still doesnt have medicare or medicaid coverage unlike the vast majority of disposal insulin pods. Although given the recent dexcom decision, its possible the
