When investors are pessimistic about a stock, it's sometimes the optimists that end up coming out ahead. In that vein, DexCom's (NASDAQ: DXCM) shares aren't performing up to their usual standard this year, with its stock price falling by 36% due to mediocre revenue growth and a regulatory delay.\nStill, there's little to suggest that the medical device manufacturer is going to continue to struggle moving forward. For the optimists in the audience, there are even a few signs that things are already looking up. Let's examine three reasons why this stock is still worth buying despite its recent stumbles.\n1. Recent delays won't mean much in the long term\nThe first reason to buy DexCom stock is that it's slumping as a result of short-term issues that won't have much of an impact once they're resolved. Its latest continuous glucose monitor (CGM) in development for diabetes management, the G7, hit a snag in its approval process with regulators at the Food and Drug Administration (FDA). Apparently, regulators found some minor issues with the device's software package that required the company's attention to remediate, causing a delay. Now, the monitor is slated to launch in Q1 of next year, making it roughly a quarter behind schedule.\nInvestors who buy the stock today will get the benefit of cheaper shares compared to prices a few months ago. Then, when the G7 ultimately launches in the U.S., DexCom's revenue growth will likely pick up once more, and its stock price should follow. Eventually, once the G7's manufacturing ramp-up is completed sometime in 2023, shareholders should also see some gross margin improvement, which could drive further gains.\n2. Penetration of international markets is rapidly deepening\nThe single biggest argument in favor of buying DexCom is that its glucose monitors are selling like hotcakes in its international markets. The business currently makes 27% of its total revenue from sales outside the U.S., up from 23% in 2021.\nFurthermore, its international revenue is growing much faster than domestic sales, posting a gain of 41% year over year in the second quarter. Looking at the last few years, that pace isn't too much beyond the norm. That's quite favorable for investors as its international growth is accelerating right when sales in the U.S. are starting to lose momentum.\nTo get a feeling for what its market penetration efforts look like, consider the company's recent launch of its DexCom One package in Eastern Europe. Within a mere two months, at least 1% of the eligible patient population in Lithuania, Latvia, Estonia, and Bulgaria had purchased the package -- and all while paying out of pocket, meaning that people were willing to spend quite a bit more than they might have with the help of insurance.\nIn the long term, DexCom will continue to expand its presence in these international markets, which should enable it to continue to growing for years.\n3. Theglobal marketfor CGMs is expanding\nPatients use DexCom's products to control their diabetes. With more people expected to be diagnosed with diabetes in the future than there are today, it's (unfortunately) safe to say that the business will see its addressable market size continue to grow over time -- and sooner than one might expect. Management estimates that the global number of adults with diabetes will increase from 537 million in 2021 to as many as 783 million by 2045.\nWhen paired with its ongoing entry into new countries, the expanding patient population will lead to a tripling of the company's total addressable market outside of the U.S. by the second half of 2023. In other words, those newly diagnosed people are going to need help to manage their blood glucose levels, and without the company's hardware, they might be stuck using older and less comfortable methods, like pin-prick blood glucose testing.\nAnd since it's a hard sell to convince people that getting poked in the finger to draw blood multiple times per day is something worth doing when there's a better alternative, many will probably end up choosing one of DexCom's monitors, which could help bolster its stock.\n10 stocks we like better than DexCom\nWhen our award-winning analyst team has a stock tip, it can pay to listen.

India’s Sensex ended the day essentially flat, down 0.06%, China’s Shanghai Composite and Australia’s ASX All Ordinaries declined 0.54% and 0.55%, respectively while Japan’s Nikkei fell 0.65%, Taiwan’s TAIEX dropped 0.74% and South Korea’s KOSPI declined 0.90%. Hong Kong’s Hang Seng led the way, down 1.96% on a broad selloff led by Health Technology and Health Services names while Transportation and Communications sectors provided the only relief. By mid-day trading, major European equity indices are down across the board and U.S. futures point to a positive open later this morning.\nAt 8:30 AM ET, the much anticipated July Consumer Price Index (CPI) report was released: The headline figure for the month was expected to fall to 8.7% from June’s blistering 9.1% reading with core CPI that excludes food and energy ticking higher to 6.1% in July vs. 6.0% the prior month. The actual numbers show that inflation hit 8.5%, and core inflation was 5.9%. With the national average retail price for a gallon of gas falling through late June and July from its June 14 high of $5.016 per gallon per data from AAA, forecasters had expected the month over month decline in the headline CPI for July. The July Employment Report also showed wage inflation ran hotter than expected during the month.\nLet’s also keep in mind that we will be facing a “wash, rinse, repeat” cycle when it comes to inflation data and expectations for the Fed given tomorrow’s July Producer Price Index report.\nData Download\nInternational Economy\nProducer prices in Japan rose by 8.6% YoY in July, compared with market forecasts of 8.4% and following an upwardly revised 9.4% the prior month. While marking the 17th straight month of producer inflation, the latest reading was the softest since last December.\nChina's annual inflation rate rose to 2.7% in July from 2.5% in June and compared with market forecasts of 2.9% but even so the July figure marked the highest reading in the last year. The country’s Producer Price Inflation figure for July eased to a 17-month low of 4.2% YoY from 6.1% the prior month and less than the market consensus of 4.8%.\nAnnual inflation rate in Germany was confirmed at 7.5% YoY for the month of July, down slightly from June’s 7.6% reading but still above the March and April figures of 7.3%-7.4%.\nThe annual inflation rate in Italy slowed to 7.9% YoY in July from June’s 8% reading matching expectations for the month. While energy prices declined, prices for food and transportation rose at a faster pace.\nDomestic Economy\nThis morning we have the usual Wednesday weekly reports for MBA Mortgage Applications and Crude Oil Inventories from the U.S. Energy Information Administration. At 10 AM ET, Wholesale Inventories for June will be published, and the figure is expected to rise 1.9%. While investors and economists will keep more than a passing interest in those reports and data, as we discussed above, it will be the July Consumer Price Index report at 8:30 AM ET that will shape not only how the US stock market opens today, but also expectations for the Fed’s next course of monetary policy action.\nThe U.S. Energy Information Administration (EIA) expects domestic production of crude oil, natural gas and coal will all increase next year compared with this year. It forecast US crude production rising 6.7% to an all-time annual high 12.7M bbl\/day in 2023 from 11.9M bbl\/day in 2022, US natural gas output climbing to 100B cubic feet (cf)\/day from 97B cf\/day, and US coal production inching up to 601M short tons in 2023 from an expected 599M this year. The EIA also modestly increased its 2022 average nationwide gasoline price forecast to $4.07\/GALLON vs. $4.05 if called for last month. It now also sees 2023 prices at $3.59\/GAL vs. its previous forecast of $3.57.\nMarkets\nStocks continued in their holding pattern waiting for the latest CPI print save for some fundamental stories pushing Technology names and small caps around. The Dow and the S&P 500 were down slightly at 0.18% and 0.42%, respectively while the Nasdaq Composite dropped 1.19% and the Russell 2000 closed down 1.46% on the day.
