One of the Best Penny Stocks to Buy in October Has 391% Upside

In mid-September, drone attacks destroyed two of Saudi Arabia's biggest oil refineries.

This kicked off a stock sell-off, especially in the energy sector. But it's also creating a massive opportunity in penny stocks.

In fact, one of the best penny stocks to buy in October could see more than 391% upside in the wake of those attacks. It's an American energy firm ready to fill the gap from Saudi Arabia's disrupted output.

Between the trade war and global tensions rising, volatility is on the rise again. The CBOE Volatility Index (VIX) just rose above its 50-day moving average. Fortunately, volatility is a good thing for the top penny stocks to buy this month.

Since penny stocks have low share prices, the slightest movement in price can result in massive gains. A $0.50 upward move for a $1 stock is a 50% boost. And it could happen overnight.

Now, of course, penny stocks are a speculative investment. A $0.50 move downward could result in a 50% loss. That's why we recommend putting no more than 2% of your portfolio toward penny stocks.

But the best penny stocks to buy in October offer an extremely lucrative opportunity for growth. Plus, entry points are low as well.

To see the type of growth that's possible for penny stocks during market volatility, just look at last week's best penny stock, T2 Biosystems Inc. (NASDAQ: TTOO). It rose more than 107% after signing a multimillion-dollar contract.

As you can see, volatility can be a good thing for penny stocks.

One of the Best Penny Stocks to Buy in October Has Much Higher to Go

Our top pick is Antero Resources Corp. (NYSE: AR). It's based in two states, Delaware and Colorado, and it looks for hydrocarbon across the United States.

Antero finds and sources both oil reserves and natural gas in North America. And most of its reserves are in the Appalachian basin. The U.S. Energy Information Administration forecasts U.S. output of oil should climb by almost 1.5 million barrels daily over the coming year. Couple that with Saudi Arabia's disrupted supply, and demand will be even higher for American oil.

If these projections hit, the United States will also become the largest global producer of oil, with more produced than either Saudi Arabia or Russia.

And AR's profitability depends on domestic fossil fuel output.

In fact, as global oil demand surges, AR is poised to profit.

Analysts estimate that the share price could surge to a high of $15 - a 391% gain over today's $3.05 share price.

That's why AR is one of the best penny stocks to buy in October.
