As a central supplier to major semiconductor manufacturers, UMD is perfectly positioned to profit from the semiconductor industry's global boom.

You see, semiconductor chips are an essential part of crypto mining and esports - two of the fastest-growing digital industries.

Esports are multiplayer video game competitions for professional gamers. Esports have bolstered the sale of the gaming consoles needed for the sport - consoles that require hundreds of thousands of semiconductor chips for production.

In 2018 alone, esports are expected to grow by 38% and break $1 billion in revenue by 2019.

Semiconductor chips are an essential part of crypto mining too - they provide the processing power necessary for unlocking blockchain algorithms.

Last year, global crypto mining increased 8,500%, helping to drive the semiconductor industry's 35% growth. Major semiconductor producer Advanced Micro Devices (Nasdaq: AMD) announced that over 10% of 2018's first-quarter revenue was the result of crypto-mining purchases.

Thanks to these strong tailwinds behind it, global semiconductor industry sales are expected to grow from $408 billion in 2017 to $439 billion in 2018 - a growth of 7%.

And UMC is cashing in on this boom.

This global production and distribution system has allowed UMC to aggressively grow its bottom line over the last three years.

Between 2015 and 2016, UMC's net income for continuing operations jumped over 60%

UMC stock currently trades for $2.74 and has serious potential to keep rising as the semiconductor industry soars.

Top Penny Stocks to Watch in September, No. 2: McEwen Mining Inc.

McEwen Mining Inc. (NYSE: MUX) is an American mining firm with operations across North and South America.

Currently, McEwen operates three mines - one in Argentina, one in Mexico, and a final operation in Canada.

These three stakes have boosted McEwen's profits exponentially over the last four years, pushing up the company's gross profits by 383%.

This jump in income has allowed McEwen to begin new mining projects in Nevada and Sinaloa, Mexico.

These mines, centered on gold and silver production, will allow McEwen to further boost the company's bottom line and spread the cost of mining across a wider range of operations.

McEwen currently trades for $1.93 a share. However, the company's aggressive expansion of its operations has analysts excited.

That's why they've given the company a target price of $5.00 - a gain of 159% over today's price.

That's a great return. However, our top penny stock to buy in September blows these returns out of the water.

It's a natural gas and electricity company on the verge of tremendous gains - analysts project over a 230% return for shareholders...

Just Energy Group Inc. (NYSE: JE) is a Canada-based natural gas and electric company operating in markets across the globe.

Just Energy supplies natural gas and electricity to 13 American states as well as Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia in Canada.

In Q4 2017, Just Energy beat earnings estimates of $0.13 by a staggering 584% thanks to an unusually early winter in Canada and a late thaw across North America.

Just Energy is expected to benefit in a similar fashion over the course of 2018 as heat waves impact large swaths of the company's customer base, elevating air conditioner use across the continent.

The prospect of gains from extreme climate conditions has analysts calling for a high price of $9.99 - a 236% gain over today's price of $2.97.

That's a tremendous gain.
