Palo Alto Networks (NYSE: PANW) and Skyworks Solutions (NASDAQ: SWKS) are two stocks investors should look at. The S&P 500 has delivered double-digit percentage gains so far in 2021, but several tech stocks have been hit by volatility as investors have panicked at the sight of rising inflation and rich valuations and are now trading at correction-level lows. But the tech sell-off has also created a great opportunity for investors to pick up discounted shares in some fast-growing companies that take advantage of hot technology trends.
