Calix Inc: 5G Stock Up 50% in 2021, Fueled by Record Q1 Results

calix stockCalix Stock on a Tear; Outlook Is Bullish

Calix Inc (NYSE:CALX) is one of the best 5G stocks that few investors seem to be discussing around the water cooler or through video conferencing. But they should be.

When I wrote about CALX stock back in November, it was trading at $23.94. It has rallied by 85% since then. Calix stock has actually been outpacing the broader market for the past year. The stock is up 343% year-over-year and approximately 50% year-to-date.

Bullish investors have been sending tech stocks considerably higher over the last year. Some tech stocks have deserved the attention, but others have not. CALX stock is one of those tech stocks that comes by its eye-watering gains honestly.

In the third quarter of fiscal 2020, Calix Inc reported record revenue and earnings. It did the same in the fourth quarter. That helped the telecommunications equipment manufacturer enter 2021 on a strong financial footing.


Just recently, Calix Inc did it again, reporting another quarter of record results that topped its own aggressive financial guidance. Those results included record net income, the company’s third consecutive quarter of positive free cash flow, and the highest reported cash balance in its history.

2020 was a fantastic year for Calix, but by all accounts, 2021 is shaping up to be even better.

Analyst Take

Calix stock has been trending consistently higher since the coronavirus-fueled crash in March 2020. The only real hiccup was the March 2021 sell-off in the broader tech sector.

But CALX stock has rebounded significantly since then. That’s in part because of the company’s record financial results, which included the first time Calix Inc reported positive first-quarter generally accepted accounting principles (GAAP) net income in its history.

The company started the second quarter of 2021 in the strongest financial position in its history, and it’s in a perfect position to execute its near- and long-term goals. That bodes well for Calix stock investors.
