3 Marijuana Stock Risks No One Is Talking About

This has truly been a year to remember for the marijuana industry. The biggest event of the year is unquestionably the legalization of recreational pot in Canada on Oct. 17, 2018. Having promised to greenlight adult-use weed for years, Prime Minister Justin Trudeau held true to his word. When the industry is fully up to scale toward the beginning of the next decade, it could be generating in excess of $5 billion in added annual sales.

But this is far from the only news that's made headlines in 2018. We've witnessed two new states -- Utah and Missouri -- legalize medical marijuana in the United States and saw the first cannabis-derived drug get the thumbs-up from the U.S. Food and Drug Administration (FDA). And Canada-based Tilray became the first marijuana stock to IPO on a reputable U.S. exchange.

Everyone is overlooking these risks

As I said, it's been a busy year -- and it's well reflected in the rising share prices of pot stocks since the beginning of 2016.

However, despite their incredible growth prospects, marijuana stocks aren't without risks. Many of these risks have been well-documented, but some are flying so far below the radar that practically no one is talking about them. Here are three of these top under-the-radar risks.

1. Fair-value adjustments swing both ways

One thing all investors need to be aware of when investing in Canadian-based marijuana stocks is that they report their income statements using International Financial Reporting Standards (IFRS), which differs from traditional GAAP reporting that investors in the U.S. are accustomed to.

As agricultural companies reporting under IFRS accounting, marijuana growers are required to recognize the fair value of their biological assets (i.e., cannabis plants) throughout their grow cycle. Remember, cannabis plants can have different values based on whether they're in the process of growing, are flowering, or have been harvesting and/or processed. It's up the growers to assess this value, as well as the estimated cost to sell these assets. That's right... pot stocks have to guess what their cost of goods sold will be prior to actually selling their product.

As you can imagine, this can lead to some wild fluctuations in the fair value of these assets from one quarterly report to the next. In recent quarters, capacity expansion has led to a surge in fair-value recognition, pushing profits for marijuana stocks arbitrarily higher. For example, Aphria (NYSE: APHA) recently reported a gross profit of 8.5 million Canadian dollars, which included CA$13.3 million in sales and approximately CA$4.8 million in production costs. However, fair-value adjustments to inventory and biological assets ultimately wound up adding CA$5.3 million to Aphria's gross profit.
