GoPro's turnaround is taking shape

Shares of GoPro climbed 6.4% today, extending last week's 14% rise amid continued investor optimism following the company's encouraging preliminary quarterly results. 

Early last Thursday, GoPro announced that revenue in its third quarter will arrive at the high end of its guidance, which called for a range of between $290 million and $310 million. Gross margin should also be near the top of GoPro's previously expected 36% to 38% range, which will mean the company will return to adjusted (non-GAAP) profitability during the quarter.

"Consumer demand for GoPro products is strong," added GoPro Chief Operating Officer CJ Prober. "Channel inventories have been reduced and we're incredibly excited about the upcoming launch of two great new products, HERO6 and our 5.2K spherical camera, Fusion."

This progress is nothing new; GoPro management promised last quarter that the company would return to adjusted profitability by the end of 2017, while at the same time suggesting that their next-gen cameras would launch in time for this year's holiday season.

But considering production issues with last year's Hero 5 launch and a subsequent recall of its Karma drone absolutely crushed the stock and effectively prefaced its current need for a turnaround, it's good for investors to hear that everything is going as planned right now. Coupled with the broader rise of tech stocks today, it's hard to blame GoPro bulls for bidding up shares again.

Universal Insurance rides the tide higher

Universal Insurance Holdings stock spiked 12.3% as investors in the Florida-based insurer ruled out a worst-case scenario for damage caused by Irma, which was downgraded from a hurricane to a tropical storm this morning. For perspective, policies in Florida comprised 88.3% of Universal Insurance Holdings' direct written premiums and 76.3% of its total insured value in its most recent quarter.

But we should also be careful not to minimize Irma's negative impact. Earlier today, catastrophe modeling firm AIR Worldwide estimated Irma's insured damage would cost the industry $20 billion to $40 billion. But that range was narrowed from AIR Worldwide's more ominous estimate on Friday for potential damages of $15 billion to $50 billion.

If there's one thing the market hates, it's uncertainty. Investors are rightly encouraged that the high end of those damage predictions shouldn't come to fruition. With Universal Insurance Holdings stock still down nearly 30% so far in 2017, it's no surprise to see shares staging a modest rebound today.
