Sierra Wireless (NASDAQ: SWIR) is often called a " pure play " on the Internet of Things (IoT), which connects various gadgets to each other and the cloud. Sierra is the world's largest manufacturer of 2G, 3G, and 4G LTE embedded modules and gateways for those devices, and the stock almost hit $50 per share in late 2014 on rising expectations for the IoT market.

This indicates that Sierra exercises cautious cost controls, and that it can continue growing inorganically to expand its IoT footprint and offset top line declines. If cash levels fall but interest rates remain low, it can take on debt to keep expanding.
The valuations and verdict
Sierra Wireless' future might look murky, but I believe that its price-sales ratio of 0.8 and enterprise value-sales ratio of 0.6 will limit its downside potential, even if sales keep declining in the near term.
Therefore, I don't think Sierra is a risky play at current prices, and its stable cash flow and clean balance sheet should soften the blow of its top and bottom line declines -- as long as they eventually recover. So if you're a patient investor who can stomach some near-term volatility, I believe that Sierra's long-term rewards should outweigh the near-term risks.
