After "The Golden State" legalized recreational cannabis sales on Jan. 1, 2018, we uncovered three California marijuana stocks expected to deliver once-in-a-lifetime fortunes.
You see, analysts project that California marijuana sales could reach $20.2 billion.
Those who invest in the new "California gold rush" now will make the largest long-term profits.
And once small pot stocks go from $1, to $10, to $20, or more... you may never see a chance like this again.
But not every marijuana stock is a winner. In fact, there are hundreds of marijuana stocks that absolutely do not deserve your hard-earned money.
Worst of all, there are even scams designed to make others rich while your shares plummet. That's why today, as a service to Money Morning readers, we had to provide all the details about the three biggest rules to know before buying California pot stocks.
Here's how to profit from the $20.2 billion California cannabis industry while also practicing "safe" investing.
Rule No. 3 for California Marijuana Stocks: Limit Your Exposure
No more than 2% of your overall stock portfolio should consist of penny stocks.
This allows you profit from the massive industry without risking the majority of your investing capital.
Penny stocks are known for their volatile price swings, like we saw on Jan. 4, when U.S. Attorney General Jeff Sessions ended an Obama-era DOJ cannabis policy.
But if only 2% of your portfolio consists of penny pot stocks, you won't succumb to panic investing, buying high and selling low.
On top of limiting how much you allocate to cannabis stocks, investors also need to avoid message boards and sites attempting pump-and-dump schemes....
Rule No. 2 for California Marijuana Stocks: Watch for Scams
Unfortunately, there are numerous pump-and-dump scams in the marijuana industry.
Back in 2014, four individuals were accused of artificially inflating the price of six stocks - two being cannabis stocks - through manipulative trade tactics designed to increase transaction volume.
PHOT prices opened at $0.15 on Jan. 2, 2014, and climbed all the way to $0.78 per share by March 17, 2014. The HEMP stock price opened at $0.23 per share on Jan. 2, 2014, and skyrocketed 1,260% to $3.13 per share on Feb. 6, 2014.
However, PHOT prices collapsed 85.89% to $0.11 per share by May 12, 2014. The HEMP stock price also fell to $0.26 per share by Oct. 8, 2014, a loss of 91.69% from its all-time-opening-high price of $3.13 in 2014.
Two people involved with the scams were sentenced to jail. Investors who bought in at the peak lost almost all of their money.
Here's how it works: When trading volume is increased and other investors see the activity, some investors buy shares of this "hot stock" without asking any questions.
They may believe insiders know something they don't and fear they are missing out.
When the demand sends prices higher, the pumper cashes out and everyone else is left holding a bad investment.
